I need somebody to school me on pullling codes from a car equipped with OBD1.
I have a 1990 Celica GT-S, 2.2 5SFE motor, 109K on motor, 190K on car. I recently got a CEL on my way to work the other day and I have no clue how to diagnose it. It wasn't accompanied by a change in engine performance and a check under the hood doesn't reveal anything obvious. If its something stupid like an O2 sensor or something emissions related I can gaff it off and ignore it, but if it's something important I want to know. I'm pretty mechanically inclined, meaning I can take shit apart and put it back together correctly, but I suck at anything electrical and I suck at diagnostics. If anybody could point me in the direction of an OBD1 for noobs primer or something with big pictures and small words I'd appreciate it. 
Thanks. |
| Not sure the difference between 1 and 2 but you can often go to a auto parts store and they will read the code for you. It maybe the basic code reader and just give you a number but a internet search can reveal what that code is for. Also basic code readers are not super expensive and always a good tool to have in the home workshop. |
