According to what I've read, a code 12 on your vehicle is the "all clear" code. I haven't found any information to indicate otherwise. What was said is that if you had a pair of fail codes, for example - let's use 15 and 34 for argument's sake - when you scanned the computer, you'd see 15, 34, 12, and then they'd repeat. The 12 was an indicator at that point that you had seen all the codes that were stored, and that they would now begin to repeat. If you have no codes stored, you'd see 12 and that's it.

Trying to find out which pins to cross for engine codes and the location on 1995 isuzu pickup


Hello ipontrees40: My name is Roger and I will help with your answer. Locate the ECM on the left kick panel. There will be a lead of wires that has 3 leads hanging. Connect the white and black wires together. Turn the key on and observe the check engine light. Should flash i sequeince of 12, will flash once pause followed by two quick flashes. This is code 12. Any codes after the 12 will be stored codes. Be sure not to start the engine when checking the codes. Should you start the engine you may not receive the correct information. The codes will be read as slow flash followed by a long pause followed by quick flashes. For examle a code 42 would be 4 slow flashes followed by 2 quick flashes. After the computer has read all storer codes it will go back to code 12. After you repair the problem you can clear the codes by either removing the negative battery cable or #3 fuse for ten seconds. Remember just because there is a code does not mean that part is bad. You need to follow basic trouble shooting to make a propper repair. Just replacing parts becomes expensive. I attatched a picture of the jumper wires to the computer to help in identifying them .
Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Rogerrogerf1_52.jpg

1995 chevy p/u with 4.3 engine 1500 series.


code 12 is always present in gm motor products. it simply means no tach signal because engine is not running. i would go with the simple first and clean the throttle body real good . that takes care of 99% of idle problems.

I have a 92 chevy 3500 w/ throttle body 2wd. its showing me error code 12. the manual doesnt have a 12 code for this truck.


code 12 is the diagnostic code. its only purpose is to let you know that the system is in diagnostic mode. if this is the only code you are getting, your system is fine.
