I have got the p1633 code pooping up in my trac since around July. it causes no known problems to the vehicle, just the CEL. when cleared, the code comes back immedietly. since I have gotten the code I have :tested battery (good), replaced battery terminals, tested and replaced an alternator with a bad voltage regulator , and have checked as many body grounds as I can find. is the PCM toast? or is a harness wire broken somewhere? please help if possible
