Throttle Cable Recall on Dodge Durango

Chrysler Recall Issue 

Vehicle Got Rusted:

2004 Chryser Dodge Durango SLT.

  • Rust at -passenger corner of rear tailgate door in about 6 inches almost gone and rust above license plate. 
  • Drivers side rear panel below gas cap 4 inch area rusted through. 
  • Spots quarter sized on hood surface rust. I just bought the car used at auction; I am a dealer. 
After adding fuel injector cleaner to full tank of gas and went on highway WOT. The throttle stuck at WOT and when I put it in neutral the engine over-revved and was about to blow.
I had to stomp on brakes for all I was worth and apply emergency brake to come to a stop and shut truck off. All 4 brakes were smoking hot so I imagine I warped rotors.

Factory recall for 2004 throttler cable. I hope the dealer fixes that for free. I'm going to call Chrysler.

Troubleshooting Solution For This Problem:

Recall Issue:
There was a recall on the throttle cables on some vehicles, recall D02. If this vehicle was covered under the recall and it has not yet been performed then they'll be able to replace the cable for free.

Cool Temperature Issue:
Are you in an area where the temperatures are still below freezing? The recall was for water ingestion into the throttle cable which would cause the water to freeze inside the cable and it could then stick. If the cable was frozen when it stuck then the event would be considered recall related and there is a chance that Chrysler could get involved in a brake repair if one is needed. The dealer would have to contact the corporation and get them involved, Chrysler would be ones to make any decision regarding that.

Going To Chrysler Dealership:

Chrysler may participate in repairing the rust if it is deemed that it was caused by an issue with the paint itself. Again the corporation is who deals with all paint issues and makes those decisions. Ask them to look at the paint when you bring it to the dealer, they can determine by looking at it whether it may fit the criteria for possible coverage. If they think it may be covered then they can start the approval process.

Only the park and neutral shift indicator lights will light up not the drive or reverse first or second gear.

Dodge Instrument Cluster Light Issue

Dodge RAM 2500 4x4

2003 dodge ram 2500 5.9 cummins and only the park and neutral shift indicator lights will light up not the drive or reverse first or second gear.

Troubleshooting Solutions For This Problem:

As per problem described it's possible that the instrument cluster itself could be causing this but that's not very likely.There are other possibilities too.

Faulty Range Sensor:

Most likely the problem is with the range sensor in some way. The range sensor is on the left side of the trans and is what reports shifter position. It has a plunger that contacts a piece on the valve body rooster comb an varies a reference voltage based on shifter position. A bad range sensor or sensor wiring issue will cause your problem.

Broken Range Sensor Guide
On the rooster comb where the range sensor contacts there is a plastic guide. If this guide is damaged or broken off then it will also cause your problem.

Getting this possibilities checked will help.

Dodge Grand Caravan SXT Fan Not Coming ON When A/C Is ON?

Engine Cooling Fan Will Not Come ON

My fan relay is working when engine gets warm. My problem is that the fans do not come on when the ac is on and engine temp is below the trigger point.

Troubleshooting Solution For This Problem:

Before Confirming The Fault For the Problem.Understand how The Engine Cooling Fan Turns ON.

A/C Pressure Transducer:

A/C high side pressure is monitored by the a/c pressure transducer. The transducer is an input to the powertrain control module (PCM) and this is how the PCM decides when to run the fan. When high side pressure increases then it will turn the fan on, duty cycling it to control pressure.

Using scan Tool to Inspect Transducer Pressure Signal:

Obviously the fans work so the relay, fans and wiring are all ok. What I would do is use a scan tool to look at the transducer's pressure signal and compare it to what is seen on a mechanical gauge. If the transducer has failed or there is a wiring issue then it could be reporting an incorrect pressure and the PCM thinks pressure is lower than it actually is and it doesn't think it needs to run the fan.

Incorrect Transducer Signal:

If the system is properly charged even if the fan never came on it still shouldn't vent. Once the PCM sees pressure go high enough it will shut the compressor off before it gets to the point of venting. This is more proof that you very likely have an incorrect transducer signal.

Jeep Grand Cherokee Security system malfunction

Security System issue On Jeep

Problems Like 94 Grand Cherokee that will not start Due To Security Alarm Disabled.

Security alarm Getting Off

Alarm honking Intermittently

Jeep security Alarm Issues


Troubleshooting Vehicle alarm Issues:

As per the model and year of the vehicle this has only the factory security (VTSS) and not an aftermarket system?

Why The alarm goes Off?

Once VTSS is armed then the alarm will go off when it sees a door open without the system being disarmed (unlock button on the key fob or unlocking a door).

As Per The Problem
Most likely it is seeing one of the door ajar switches close and that is what is setting it off. It could be one of the front doors, but the problem is most often one of the switches on the liftgate. There is one for liftgate ajar and there is another for the flipper glass. Both switches are the same part number and interchangeable. If it has a vehicle information center sometimes you will see a liftgate ajar warning come across when the gate and glass are both closed.

Things You Can Try:
Make sure all doors, the liftgate and glass are closing properly. If they are then I would try disconnecting the flipper glass switch first and then the liftgate ajar switch and see if the problem goes away.

Can Be Issue With switches:

The system should have disarmed no matter what when you turned the key in the door. There is a disarm switch on the back of the lock cylinder that is wired to the VTSS module. These switches do fail and sometimes they fall off the cylinder. The next time it goes off try disarming from the passenger door of liftgate lock cylinder. The driver's door is the one most use and is usually the first to have a bad disarm switch.

Faulty VTTS Module

It's possible that the VTSS module is the cause of both issues also, but mostly I would say you probably have a bad flipper glass switch and an issue with the driver's disarm switch.

Chrysler 300 Aftermarket Radio Issue

Chrysler 300 Radio Problem

Car radio is one of the good entertainment source in the car,if it stops working getting it repaired becomes necessary.

Airbag Light Goes On And OFF After Replacing Radio

Aftermarket Radio installing Issue

After installing an after market radio on 2006 Chrysler 300. Now the airbag light goes on and off. If I change back to the factory radio the air bag light stays off.

Solution: A wiring Issue Or Non-Compatible Radio Unit:

There are few possibilities to be checked:

  • First make sure you got exact aftermarket radio,which is compatible for your car model.
  • If this for sure only happens with the aftermarket radio in place then most likely you have a wiring issue. 
  • The factory radio is on the CAN B communication bus to allow communication between it and other modules. 
  • If anything from the replacement radio is connected to the bus wires then it will take the bus down and could turn the airbag light on. 
  • If the wires are being pinched when the radio is in place and are shorting to ground it will also do it.

Things To Try:

The first thing I would do is remove the radio and find the white and white/orange wires that are next to each other in the original connector. Make sure these wires are not connected to anything.

Many-a-times several of the pins in the connector get bent; including the pins connecting the white and white/orange wires. Just check and straighten out the pins and all will get good.

Chrysler Town & Country Alternator Problem

Chrysler Alternator Issue

Troubleshooting Chrysler Alternator Problem.
Alternator Controls Vehicle Charging System.

Problem With 2001 Town and Country  3.3L.
When van is in gear and at an idle, speedometer is jumping up to 30mph and back to 5mph. If you let the van roll and then press the gas pedal all is ok. if you try and start off from a dead stop, van coughs, jerks and then moves. If the Air conditioning is on it is twice as bad as when it is off.

Solution: First Check the Basics

First get the regular tune-up done for items such as spark plugs and wires? I have seen the jumping speedo in older vans, which was caused by poorly routed, and electrically leaking spark plug wires.

If Vehicle servicing tune is done and its not helping then,
You have a bad alternator that is inducing electrical noise into the output speed sensor signal and that's why the speedometer moves on it's own and these things are happening.

Easy Way To Confirm The Problem With Alternator:
Reach down on the back of the alternator and unplug the field connector. Start the engine and drop it in gear, you will almost surely see the speedometer stays at 0. If it stays at 0 with the alternator unplugged then replace it.

If Alternator checks out faulty then replace it.
Its better off replacing the alternator with a new or re-manufactured one rather than trying to repair the faulty alternator again. You should be able to pick up a re-manufactured alternator starting at about $150. Autozone service center carries them with a lifetime warranty for $170.

2004 Dodge Ram 1500 Idle Issues

Idle Goes Up And Down

Idle Problem On Dodge

Engine continues to idle high

Truck jerks into gear

Idle Gets Erratic 

United States 2004 Dodge Ram 1500 Vehicle

Q:  2004 Dodge Ram 1500 QC SLT 4.7L automatic engine with 165,000 miles. Idle continues to fluctuate. Occasionally while coming to quick stop the engine continues to idle high. When I go to take off my truck moves slow for a few feet then jerks into gear. Also, when put it in park or drive it sometimes jerks into gear. 

A: Throttle Position Sensor: 

Most likely its a throttle position sensor (TPS) issue. The TPS is mounted on the left side of the throttle body and tells the engine and trans controllers how far the throttle is open.

Faulty TPS 

When the sensor gets worn it will start to create small voltage spikes in it's signal and the engine controller things you are opening the throttle, so the idle can be erratic. If the voltage just stays high then so will the idle.

Trans Controller And TPS Signal:

The trans controller also receives the TPS signal and uses it for shifting control. If the idle fluctuation and the trans symptoms started at about the same time then the TPS is likely causing the shifting issues too.

TPS Signal Monitoring:

The TPS signal can be monitored with a scan tool or labscope. You can also try unplugging it while the idle is fluctuating, if it straightens up then replace the sensor. You can also tap on the sensor or wiggle the connector, if this has any effect on the engine then replace the sensor.
