P0455 Evaporative Emission Control System Leak Detected (gross leak)
P0743 Torque Converter Clutch Circuit Electrical
P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0442 Evaporative Emission Control System Leak Detected (small leak)

thats great...but, i need to know the start point for all of these codes. i do have code description, but, how do i fix them?...means if you have any tips on 'what to look for' kind...that will be great.

thanks and regards

P0445 and 0442 indicate there is a leak in the evap system. Check the gas cap to see if it is tight you may need a new one. As for the gross leak you could have a bad hose going to the canister under the drivers side of the vehicle or the canister itself may be bad and need replaced. The P0134 O2 sensor indicates the sensor is bad and needs to be replaced. As for the TCC code I really have no idea where to start on this one. The P1297 indicates a problem with the injection system. With this combination of codes you may have a PCM/ECM going bad. The P1491 code I can't find.

thanks for the reply....i am sorry for the wrong capacity of my engine....my car is 3.0L...

one question i have....does my car is equiped with TCM (Transmission Control Module)?...

the reason i am asking is that in the Haynes manual, they are showing that the module is in the car on lower right front of the car....

i dont see anything there, and i dont even have the relay for TCM and the fuse.

Please help me.....is there any other location for TCM?....

please let me know if the car is equipped or with TCM or not.

Thanks and Best Regards

updates:
as i said, i have just bought this car....i wonder why there was few things - which seems to me that was intentionaly done previously - i think by the previous auto shop. (coz the guy i have bought this car from is very naive)

1. the oxygen sensor was disconnected
2. air filter had oil in it - the reason was overflow oil in the engine...

after fixing these problems and cleaning the throttle body and intake, i am going to try the car to see the results.

thanks

(Why the people in this forum dont reply or help?)

just keeping you posted you all.

i got rid of 5 codes out of 6....the only code left is P0743...which i will fix by tommorow...

still there are no people to help in this section of the forum.

anyway....best regards

the P0743 means that you are having a problem basically with your solenoid pack. When you get that checked out, you might be able to have your PCM flash programmed thus eliminating that code you have for the Torque Converter Clutch Circuit. I do this a lot b/c I work for a Dodge dealer. If you need my advice, feel free to contact me and I'll help in any way I can.

ok everybody....my car is fixed now....the last code P0743 (pain in the neck) is also fixed...

i have found the original Dodge Caravan 31TH transmission Service manual which helped me a lot to fix the trouble...

if any of you face transmission problem, please leave me a line and i will send you that manual to help.

Thanks and best regards

Hello i need help how to fix the p0743 problem on my 1997 3.0 caravan ! Im geting crazy any help would be apreciated thanks

Unfortunately the thread you brought up is over 4 yrs old. Your code is for an electrical problem. P0743 Torque Converter Clutch Circuit Electrical. Power is sent through the solenoid and then to the computer so the computer can ground the circuit to turn it on.This code means the computer is not getting the power on that pin so it can activate the solenoid. You didn't state what repairs you have done so far or what you have checked. If you have a library card you could do some research here.
http://rpa.alexandria.lib.va.us/rpa/default/odb.htm You have a Chilton Library at your disposal. Thats a start for now since I don't know what you have checked or done at this point.
