    Found the problem

    diagnostic plug under dash was broken& the contacts were touching causing the computer to go screwy

    how did that happen maybe recent service tech did this perhaps sounds like some one might have aggressively ripped the OBD 2 plug out of the under dash receptacle??

Change the Cam Position Sensor.. It done the same thing on mine. The sensor runs about
40. to 60.00 at most parts stores Your gonna have to take off the upper intake or plenum to
get access to it. Top of the engine right side, you'll see it

Sounds like the shifter cable is corroded to the point that it might snap. Replace the shifter cable. Best wishes to you.

SOURCE: 99 chrysler cirrus lxi won't shift out of 2nd, no speedometer

Had the same problem on my 1999 cirrus lxi. Replaced the output speed sensor on the tranny and topped off the tranny fluid... cleared the check engine light and the cirrus ran great. Caution...the output speed sensor reqires removal of the front left tie and plastic weatherproofing to replace. once you find it's locvation, the replacement is relatively easy.

The 700 is the limp mode, as I recall. One or both of the sensors are failing, and they are not too expensive to replace. Once replaced, then using the OBD tool, you can delete the fault codes and then be able to shift into all the gears.
I have written about this solution in other blogged questions, and so have others. Under the car, on the Driver side of the transmission are two electric sensors. They lay horizontally on the trans just behind where your foot would go on the accelerator and under the floorboard. The electricl clip sockets pull out with thumb pressure on each socket. DO NOT pull on the wires EVER. Unplug each socket, and replace one at a time. Use a 1" deep well socket and unscrew them from the side of the trans casing. Do one at a time starting with the one on the left, the Input side,; Then the output side.
The reason why I replace them both is that they are cheap- about $20 apiece- and REALLY: do you want to go under there twice for twenty bucks? If so, then just replace the one on the LEFT- the Input sensor. You then MUST RESET THE CODES with the OBD tool for the transmission side of the tool, then GO!

Chrysler 300m oil light came on while driving and the engine then shut down. the oil light is still on the dash and the car wont start. turns over fine just dont run


Are you SURE that it was Oil Light then Engine Shut off? There is not a ENGINE SHUT OFF if the light comes on that I am aware of and I have worked on quite a few 300's.

I would be trying to start the vehicle by:
Verify Fuel Pressure
Spray Starting Fluid in the Intake and see if it starts then
Are you sure there is Spark?
CRANKSHAFT SENSOR went bad

I have a 1999 Chrysler 300M. Simultaneously, the Check Engine light came on, the speedometer stopped working, and the car doesn't shift out of 2nd gear. What's the likely problem?


these vehicles have alot of problems with the tcm( tranmission control module) internal failures of trans speed sensors. your car is currently in "limp in mode" to protect your trasmission!!!

Will not move from 2nd gear help PLEASE?


Your transmission is in a "limp in" mode. There are 2 sensors that need replaced. Total cost should be less than $100. I had it happen to me on my 99 300m. The sensors limit the speed to about 25 mph and the RPM rev's high. Just get the sensors replaced.

Temp guage in red' dummie light on engine not hot


Sounds like a faulty sensor, if the actual temp is 195/215. The ICM is processing the information it receives from the sensor and performs accordingly. A complete diagnostic scan would be helpful in determining the proper repairs needed to correct the problem.
Good luck...i hope this helps, please rate me a fixya.
