Top 10 2001 Chrysler 300M Questions & Answers

This is what sets the code.

Engine started, engine running, and the PCM received a message over the CCD bus from the Transmission Control Module (TCM) that it had detected a problem and set a trouble code in memory. This code sets in 1 Trip(s).
The presence of this code means the TCM detected a problem. TCM related sensor is damaged or has failed.

After everything you have done I would recommend taking it to a transmission shop, I'm sure they have seen this on Chryslers. and know what the common problems are.

When the vehicle overheats, do u check the water/coolant level in the radiator? If it has reduced, it means ur leaking and u should inpsect to c where the leak is coming from. If the level has remained the same, probably ports are blocked or something to that effect. Keep me posted though

The 300M is equiped with a rev-limiter. The technology is designed to protect the engine. It keeps you from blowing it up when it has no load on it...If it is driving and shifting ok, and you have no check engine light on...there is nothing wrong.
Why would want to rev the engine past 4000 rpm in neutral anyway? Max torque comes in around 3950 RPM...
If you keep reving it up in neutral you might throw the computer in to LIMP mode, then you wont go no where.
Hope this answers your question...

Make sure that the gas cap is the correct one. If the gas cap was replaced with a different style or a locking cap this will set off the check engine light. It can tell there is a problem because it measures the built-up pressure in the gas tank. So the pressure is not building in the tank due to a loose or incorrect fitting gas cap or a loose,cracked fuel line, or bad check valve in the charcoal canister for the fuel tank vapor release line.

you need to remove upper radiator core support set on engine loosen 15mm bolt on front of alternator tensioner and 13mm bolt behind the tensioner pulley remove this belt then go under passenger front and you will see the tensioner bolt for the ac belt turn until tension is released remove belt replace belt and reverse instructions to put back together

water boils at 200* plus, you might want to check the cooling fans which involves the temp sensor, check into that

My 2003 chryseler 300m can not see the light to the temperture counsel everything work just can see the temp

This engine is what is known as an interference engine, so if the timing belt lets go like this you most likely have bent engine valves and or piston crown damage. The best advice i can give is have a new belt, water pump and automatic tensioner pulley installed and see if it starts, you may get lucky, my wife did when hers let go a year before I meant er. You can purchase a timing belt "kit" with all the parts here is the part number and price.
