Fixes for Chrysler 300 2005 - 2010 (LX)

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:  All vehicles (ZJ) (LX) (XJ) (RS)

Concern:  No start. Engine cranks but does not start. Most likely the engine died while driving. The fuel gauge shows 1/8 of a tank.

Cause:  The fuel tank is totally empty. The fuel level sending unit is failing.

Resolution:  Replace the fuel level sending unit, or the entire fuel pump assembly. Add fuel.

Details:  Always start with the basics.


Vehicle:  Most vehicles, especially with 2.7L engine (LX) (JR)

Concern:  The MIL (check engine light) is on. Scan tool reveals DTC P1281 cooling system performance and/or P0128 thermostat rationality.

Cause:  Low coolant. Coolant bottle has not been topped off at normal service intervals.

Resolution:  Top off the cooling system with the correct type of coolant. Most late model vehicles require orange coolant. Do not mix coolant types, except in an emergency. Verify that there are no coolant leaks. It is common for the black plastic coolant housing (top front of engine) to leak. Coolant housing has one or two hose connections, coolant temp sensor and bleeder screw.

Details:  (3) warm-up cycles will clear the MIL.


Vehicle:  All vehicles equipped with electronic stability control (WK) (XK) (LX)

Concern:  ABS/ESP/BAS light is on.

Cause:  First thing to check for is an alignment problem. Test drive the vehicle and check if the steering wheel is straight when the vehicle is going straight.

Resolution:  If steering wheel is turned left or right while driving straight, the vehicle needs an alignment. Perform an alignment then test drive. The warning light should turn off.

Details:  The stability control computer measures steering angle and degrees per second of steering wheel rotation. When it sees steering angle greater than or less than -0-, but the yaw sensor is not sensing a turn, a rationality fault is set and the ABS/ESP/BAS light will be on.


Vehicle:  All late model Chrysler, Jeep, and Dodge vehicles (PT) (LX) (WK) (XK)

Concern:  No start. The engine does not crank or start. When key is turned to the 'start' position, nothing happens. Battery is NOT dead.

Cause:  The immobilizer module is electrically 'locked up' or is otherwise non-responsive.

Resolution:  Disconnect the battery for a few minutes, then reconnect the battery and retest. If the engine now will start, the immobilizer module may need to be replaced.

Details:  The immobilizer module is located very close to where the key goes into the ignition lock cylinder. The immobilizer module has several names, depending on year/model: SKIM, SKREEM, WIN. Vehicles with a WIN also have a FOBIK type remote (no key).


Vehicle:  Most Chrysler/Jeep/Dodge vehicles, 2005 and newer (WK) (XK) (LX) (PT)

Concern:  The clock (on the radio) is incorrect. What is the procedure to set the clock?

Cause:  -

Resolution:  1) Hold the 'time' button until the clock hours digits blink. 2) Turn the right radio knob to set the hour. 3) Press the right radio knob in to select minutes. 4) Turn the right radio knob to set minutes.

Details:  Easy Squeezy Lemon Peazy!


Vehicle:  2005-up (WK) Jeep Grand Cerokee, 2005-up (LX) 300, 300C, Charger, etc. and others

Concern:  Airbag light is on. Passenger 'airbag off' light may be on.

Cause:  The passenger seat is out of calibration.

Resolution:  Have your dealer calibrate the passenger seat.

Details:  The passenger seat has a weight sensing system.


Vehicle:  2005 (LX) Chrysler 300 with 2.7L engine.

Concern:  The MIL (check engine light) is on. Scan tool reveals DTC P0340 camshaft position sensor circuit and/or P0344 camshaft sensor intermittent. Related symptom: the engine may have an extended crank time (hard to start).

Cause:  Software error and failed camshaft position sensor.

Resolution:  1) Flash program (update) the PCM (engine computer). 2) Replace the camshaft position sensor.

Details:  The camshaft position sensor is very easy to replace. It is on the front of the engine.


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:  All (LX) models: 2005-2008 Chrysler 300, 2005-2008 Dodge Charger, Dodge Magnum

Concern:  Power steering leak (minor). The power steering hoses are wet. Fluid loss is very minimal in most cases.

Cause:  The flexible portions of the power steering pressure hose are seeping fluid.

Resolution:  Replace the power steering pressure hose to correct.

Details:  The hose goes from the power steering pump to the rack & pinion.


Vehicle:  This particular case was a 2005 (LX) Chrysler 300C RWD with 5.7L Hemi engine.

Concern:  Customer's complaint was "engine has too much power." I road tested and found actually the power came on too suddenly. The slightest press of the accelerator pedal would cause the car to jump forward.

Cause:  The MAP (manifold absolute pressure) sensor was not reading correctly. There were no fault codes.

Resolution:  Replaced the MAP sensor to correct. There was a revised part available.

Details:  The MAP sensor is extremely crucial to correct engine operation, especially on engines equipped with electronic throttle control.


Vehicle:  2005 (LX) Chrysler 300

Concern:  Instrument panel gauges are inoperative at times. The ESP/BAS warning light is on. DTC B2107 may be active.

Cause:  The ignition switch is failing.

Resolution:  Replace the ignition switch (electrical portion) to correct.

Details:  Revised part was available.


Vehicle:  2005 (LX) Chrysler 300, also all vehicles equipped with integral key/remote

Concern:  The keyless entry remote (integral with igniton key) is inoperative. The power locks operate normally from the switches on the front doors.

Cause:  Internal remote failure, usually a soldered connection

Resolution:  Best resolution is to replace the key.

Details:  Key will need to be programmed in order to function. Engine will not start and remote will not operate until the key is programmed to the vehicle with the appropriate scan tool.
