so i just got my car to the shop and they pulled five codes. i need to know how to fix these things asap! haha
ready???
P1491 cant find diognostic in chiltons...
P0743 cant find diognostic either...
P0134... upstream H02s stays at center...(i have a bad exhaust leak??)
P1899... Park/neutral switch failure...
P1492... Battery temp. sensor 2 high...

thanx in advanced for the help i know ill get!!!

the search button is your best friend, but here's something to get you going

looky through those. all the trouble codes are in there

Batt temp sensor might be a fluke. reset and see if it comes back. If it does, change out your battery. We do not have a batt sensor, the ECU determines battery temp by various measurements detected in the battery. My MicroVat does the same thing during Starting/Charging System diagnostics.

Your front o2 is shot wether you have a leak or not.

P0743 is the torque converter circuit issue.....you have an automatic.

P1491 is the Emissions system, if i recall correctly its from the switch in the Leak detection pump failing.

My advise is check the Neutral switch and make sure its good. If not fix it then reset the ECU and see what comes back. Your trans codes my be related to that switch failure.

The P1491, reset and see if it comes back. Sometimes that will set and clear on its own due to a fluke in the system.

Replace the Front O2

Go from there.

automatic what??? my car is standard.

Then explain how you have a park/neutral switch?

Edit: Nevermind, i dont even want to hear your excuse. I will diagnose the codes themselves and leave your assumptions out. You either are posting wrong info for the code or wrong codes.

p1492....Already explained

P1491....Actually is a fault in the Rad fan relay ckt. If you have messed with the relay at all while the engien was running then that is you culprit. Could be bad relay or wiring. I was thinking of a different code.

the other two Are from an automatic ECU. so you are either giving us the wrong codes, you swapped your ECU, or you have some other real real big issues. Fix the obvious and reset

If you dont know what your doing, take it to a shop.

Dude its not automatic. We put that motor in so he's not giving you and excuse. Were changing the pcm. And no he's not giving wrong info. We pulled the codes ourselves and the first thing i noticed that was strange was that it had a torque convertor code and a park/neutral switch code. Strange since it is a manual. So relax and grab a beer and agree that this is a true dsm.

yea dude im not giving crap. yfi i changed out the pcm and now i have no lights on. thanx for ur "help" starturbotalon. and i dont need to take my car to a shop. i can do stuff myself. once again starturbotalon for all ur "help". i know the dif between an automatic and standard transmissions.

You had an auto ECU in your car didnt you.
