Fixes for Dodge Avenger 2007 - 2010 (JS)

Vehicle:  Applies to all vehicles. In this case it was a 2008 (JS) Chrysler Sebring with 2.7L engine. The basic factory warranty was still in effect.

Concern:  Check engine light is on. Scan tool revealed DTC P0301 (cylinder 1 misfire). Related symptom: Technician noted the engine had a slightly rough idle, but ran OK otherwise.

Cause:  Vehicle was driven through high water. The engine ingested just enough water to slightly bend cylinder #1 connecting rod. This caused the compression ratio to be reduced on cyl 1, causing a power imbalance, resulting in a rough idle and a misfire DTC.

Resolution:  Remove cylinder head and oil pan and replace cyl 1 piston/rod assembly.

Details:  This was yet another case where the customer withheld information. They knew the vehicle has been driven through high water, but chose to not disclose this information, perhaps hoping that the factory warranty would cover the repair. Water ingestion/flood damage is not covered by the factory warranty.


Vehicle:  The following vehicles with a console-mounted shifter: 2005 and newer (LX) body (Chrysler 300/300C, Dodge Charger, Dodge Magnum.) 2007 (JS) and newer Chrysler Sebring and Dodge Avenger.

Concern:  Shifter will not come out of Park. Vehicle cannot move because shifter is stuck in Park. Vehicle operator has engine running and brake pedal IS depressed (normal operation).

Cause:  Shifter internal mechanical failure.

Resolution:  There is a manual override button on the rear of the shifter. It is bright pink in color. You will need to remove a trim piece or cupholder insert to access the override button. Key should be on, depress and hold brake pedal, and press and hold pink override lever. At the same time, pull the shifter toward you, out of park. It may require 2 hands and considerable force. Part of the internal shifter will break/snap and then you will be able to move the shifter to reverse, drive, etc. If you are successful, this will save you a tow bill. Replace the gearshift assembly to repair permanently.

Details:  -


Vehicle:  2008 (JS) Chrysler Sebring

Concern:  Speed control (cruise control) is inoperative. On/Off switch seems to be OK, but will not set.

Cause:  The speed control switch is faulty.

Resolution:  Replace the speed control switch to correct.

Details:  New switch is a revised part.


Vehicle:  All vehicles. (JK)(ZJ)(CS)(JC)(TJ)(XJ)(PT)(KJ)(KK)(KA)(AN)(ND)(DR)(DS)(WJ)(WK)(XK)(LX)(LH)(FJ)(JR)(JS)(RT)(RS)(NS)

Concern:  The MIL (check engine light) is on. The scan tool reveals DTC P0601 PCM internal controller failure.

Cause:  The PCM (engine computer) has an internal fault.

Resolution:  Replace the PCM to correct.

Details:  This is an easy diagnosis. When P0601 is present, the solution is always to replace the PCM. There is no other possible cause. Normally the vehicle is still driveable.


Vehicle:  All Chrysler, Jeep, and Dodge vehicles. (JK)(ZJ)(CS)(JC)(TJ)(XJ)(PT)(KJ)(KK)(KA)(AN)(ND)(DR)(DS)(WJ)(WK)(XK)(LX)(LH)(FJ)(JR)(JS)(RT)(RS)(NS)

Concern:  Alternator failure. The alternator (generator) is not charging. Electrical problems.

Cause:  -

Resolution:  Hold on for a minute. Alternator failures are extremely rare on Chrysler, Jeep, and Dodge. You need to rule out the battery, wiring, and PCM first before replacing the alternator.

Details:  The alternator is controlled by the PCM (engine computer). Again, true alternator failure is very rare. In ten years as a dealer service dept tech, I have replaced maybe five alternators.


Vehicle:  2008 (JS) Chrysler Sebring

Concern:  Cig lighter/power outlet is inoperative.

Cause:  Fuse open

Resolution:  Check fuses 11 and 16 in the fuse box under the hood.

Details:  The fuse numbers are on the lid of the fusebox. The fuse box is actally a control module called the TIPM (Totally Integrated Power Module).
