P0405 EGR code on Chrysler Products

Rick — Sat, 04 Feb 2012 15:44:27 +0000

Many Chrysler products use EGR transducer to detect the actual movement of the EGR valve. The computer commands the EGR valve to open a certain amount. Then, the transducer measures exactly how far the valve actually opened. This transducer sensor has a very high failure rate. In most cases a P0405 EGR Sensor A Circuit Low is caused by a bad sensor. There are two way to go about this fix. You can buy a new EGR valve with sensor, or you can buy just the transducer. Buying just the transducer will save you money. Unfortunately, not many parts stores carry them. But you can give it a shot. First go here to find the transducer part number. Then call the parts store to see if they stock it. If not, go here to buy the entire EGR valve.

No Start – Jeep

Rick — Sat, 17 Sep 2011 15:15:02 +0000

Several people have posted questions on help forums about their Jeeps not starting. Here are some of the top reasons. Since there are several Jeep models and different designs over the years, this is just a summary. If you want detailed information on YOUR system, buy a subscription to AlldataDIY or eautorepair.net from the links below

related failures. In some cases a plastic tab breaks off the switch and allows it to flex/twist or move slightly. In others, the lock cylinder housing cracks. The switch moves enough to supply power to the lighting contacts, but not enough to power up the starter. Check the switch. If the lock cylinder housing is cracked, you’ll need a new steering column. Start checking the junk yards.

of these safety switches are know failure points. The switch is located on top of the valve body and is called the transmission range selector (TRS). Try starting the vehicle in neutral rather than park. If that does it, the TRS is either out of adjustment or corroded. Plug the connector apart and look for green corrosion. If you find it, treat it with Stabilant 22

P0750, P0755, P0760, P0765 Caravan, Voyager, Transmission in Limp in Mode

Rick — Thu, 04 Aug 2011 12:57:34 +0000

P0750, P0755, P0760, P0765 Caravan, Voyager, Transmission in Limp in Mode

The solenoid pack in these Chrysler vehicles regulates transmission oil pressure to activate the clutch packs and make the vehicle shift. The solenoid receives a pulsed signal from the PCM and the solenoid responds by opening and closing the port up to 10 times per second. This action is called “duty cycling.” So if the solenoid is open 5 times in one second, it’s at 50% duty cycle.

The PCM constantly checks the condition of the solenoid pack and reports any of the P0750, P0755, P0760, P0765 trouble codes when it finds a problem. Then it puts the vehicle into “limp in” mode so you can drive the vehicle into the shop. To confirm that the problem is actually the solenoid pack all you need is a digital multi-meter. Disconnect the electrical connector from the solenoid pack and test the resistance between pins 1 & 5, 1 & 7, and 1 & 8. The yellow/red wire goes to pin 1. All the solenoids should read 1-3 ohms. If the readings are out of range, replace the solenoid pack.

If you need a new solenoid pack, check out this link. Just enter your vehicle info at the top to double check the part number.

P2097 or P2099 Trouble Codes on Dodge Dakota and Ram Pickup

P2097 or P2099 Trouble Codes on Dodge Dakota and Ram Pickup

Dodge reports a software glitch on 2004 Dakotas and Ram Pickups. The computer can pop up trouble code P2097 (downstream fuel trim rich-bank 1) or P2099 (downstream fuel trim rich-bank 2). If the vehicle runs ok and has no driveability issues, the codes are bogus and the fix is to flash the computer with the latest software to correct the glitch.

P0116 trouble code in Dodge Dakota, Ram Truck, Jeep Liberty and Jeep Cherokee

Rick — Mon, 18 Jul 2011 01:57:54 +0000

Chrysler reports a gremlin style trouble code in 2004 Dakota, Ram Truck, Jeep Liberty and Jeep Cherokee vehicles with the 3.7L engine. The check engine will light and the computer will set DTC P0116 (coolant sensor code). You may also see assorted misfire codes, other oxygen sensor codes, and other fuel system related codes. Also, Jeeps with manual transmissions may show a stumble or hesitation when you shift aggressively through the gears. If you have any of those issues in your Jeep or the vehicle has no driveability problems, don’t start replacing parts.

The computer glitch affects these vehicles:

Ram trucks built before 4/13/04
Dodge Dakota built before 4/20/04
Jeep Liberty and Cherokee built before 4/1/04

The only fix is to get a software update by dealer or a qualified independent repair shop.

Chrysler minivan recall on Dodge Caravan and Town and Country

Rick — Thu, 23 Dec 2010 16:44:11 +0000

Chrysler has issued a recall on 367,350 2008 Dodge Grand Caravan and Town and Country minivans due to accidental airbag deployment. The problem starts with water that seeps into the airbag control module. The leaks are caused by improperly assembled heating and cooling system drain tube grommets. Water then collects on the floor and damages the air bag deployment module. The module can illuminate the air bag (SRS) light or actually deploy the airbag.

Dodge Caliber SRT4 check engine light

Rick — Mon, 19 Apr 2010 22:24:25 +0000

Owners of 2008 Dodge Caliber SRT 4 models complain of a check engine light that translates in to a specific cylinder misfire code. If the 2.4L turbocharged vehicle was built before 4/18/08, the problem is likely due to a software glitch. Re-flashing the PCM with the most current software is the only way to fix the problem.

Jeep Grand Cherokee airbag light on

Rick — Sun, 21 Mar 2010 17:03:22 +0000

Shops are reporting a high failure rate on clocksprings on these vehicles. The trouble code shows that the Driver’s side squib has an open circuit. To determine whether the problem lies in the clockspring or the airbag itself, perform this test:

Disconnect the battery and wait for the airbag system to power down (2 minutes). Remove the driver’s side airbag and put it in a safe location. Unplug the 2-wire connector going into the clockspring from the airbag control module (you are bypassing the clockspring). Install a dummy “load resistor” of 2.5 ohms into the connector. Clear the airbag code. Then recheck the codes. If the code is gone, replace the clockspring

The Jeep clockspring is NOT covered by the Caravan clockspring recall. Follow all installation instructions when installing the new clockspring or you can damage it.
NEVER spray any lubricant into the clockspring. It can damage the mylar coating on the ribbon cable

AC lights blinking on heater control Chrysler Minivans

Rick — Fri, 19 Mar 2010 22:41:44 +0000

If the battery is disconnected on Chrysler minivans, the blend and mode door actuator motors “forget” their position and must be recalibrated. Thankfully, you don’t need a scan tool to do this. Just follow these steps:

1. Start the engine and set the blower motor to high.
2. Set the mode position to PANEL.
3. Open all the A/C outlets and set temperature to COLD. Move both sliders if van is equipped with passenger controls.
4. Push and hold the REAR WASHER and the REAR WIPER buttons SIMULTANEOUSLY for 5 seconds. All the LEDs will light. The unit will start calibrating.
5. The calibration is done when just the rear wiper LED is flashing. To exit the calibration program, push the rear wiper button once. If the lights continue to flash, the program has detected a problem and you must refer to a trouble code chart

Chrysler Heater A/C Control Calibration Routine

Rick — Fri, 29 Jan 2010 19:33:41 +0000

The blend and mode doors on late model Chrysler vehicles are driven by DC servo motors. If the motors get out of synchronization, the control head doesn’t know where they are. That can result in cold air when you command heat and vice versa. It can also screw up where the air blows.

Here’s how to perform a calibration routine on Caravan, Voyager, and Town and Country. It works on many other Chrysler products as well.

1. Turn Ignition switch to ON

2) Press both the POWER and RECIRCULATE buttons at the SAME time and HOLD for at least 5 seconds.

3) The POWER and RECIRCULATION lights will flash

4) Calibration should take about about 2 minutes to complete if you have heater control and about 20-seconds if you have Automatic Temp Control system.

5) If lights continue to flash AFTER 3 minutes (manual system) or 20-seconds (Auto system), the control unit has detected a failure. You need a scan tool to pull the trouble codes (Thanks Chrysler). If there’s a trouble code stored, the lights will CONTINUE to flash until the unit completes a successful calibration OR until the vehicle has driven 8 miles.

If your Chrysler vehicle doesn’t have this setup, contact me and I’ll look up the procedure for your particular vehicle.
