2001 PT Engine Light

you can read the code from your odometer panel, with the car off, turn the key to on-off-on-off-on, you will see the code in the odometer window..

with the new gas, you probably re-tightened the gas cap, which fixed the evap leak.

Thanks Punch! It showed P0340. I`ll call tomorrow and see what that means. I must add that I purchased a Mopar locking gas cap from the dealership which replaced the eom one.

Yes, and have a paper and pencil ready and write the code number, or numbers down. They will appear one right after another until all of the codes have been read out, then it will say "done". Maybe only one code will appear.

I had a similar problem awhile back. I would drive the Cruiser a couple of miles and when it was about warmed up to operating temp the power would drop out for an instant -- like turning off the ignition -- and then resume operating. The engine fault would light up. The Cruiser would continue on like nothing happened, but the engine fault light would continue on for a few startups while I had the car out doing errands, then, eventually it would go out. I read the codes and read P0340 and P1684: No cam signal, and battery disconnect. When I got the Cruiser back home I examined under the hood for the battery connections and found them corroded with that "green stuff". I took the connections off the battery and used a roto tool with a small wire wheel to clean the "green stuff" off the connections and the battery terminals and reconnected. I haven't had the problem since.

If you want to, come back here with the code numbers and we can tell you what they indicate, if you don't have the service manuals with the codes in them.

P0340 was one of the indicators that I had. Maybe you should check your battery connections to see if they are corroded like mine were. The P0340 indicator shows: No cam signal at PCM. The PCM is the Powertrain Control Module. If a cam signal was lost for even an instant, the computer will send a signal to the engine light. In my case, the signal loss was for only an instant, and then the engine would run OK, but the engine light stayed on for a few more startups and then go out. After I cleaned the battery connections, I had no more problems with that. Of course, there could be some other loose connection instead of the battery, but I would check this first.

Tonight on the way home I had the exact same thing happen as Indago! Decrease in power then engine light. Checked codes again and along with P0340 I now have 1684. I will check the battery connections tomorrow. I will still have the dealer clean them or make further recommendations but at least I feel like an informed consumer. All of you have been an enormous help! Thanks everyone!

yeah or like most crooks they will see a woman coming and scam her blind, atleast she now knows the code so if they come back telling her some other BS she has something on her side.
