Greetings,
I recently had the car serviced and was told that it was not table to have code 21 cleared from the CEL due to the oxygen sensor heating circuit being bad (which is in the ECU?). The car had a new Oxygen sensor put in and the problem persists. The wiring was traced back to the ECU with no breaks. As a result, they took out the CEL (which I'm putting back in) Is the ECU bad or is there a way to fix this problem without replacing it? This post is related to a previous about the cat not making full boost, now i know why (Thanks!) 1988 ST-165.
If the ECU is bad and needs replacement, where can I find one?
