i have a 02 with a manual transmission that has devloped an electrical problem. two days ago my temp gauge started acting eractic from one end of the gauge to the other then my cruise light started flashing and the truck started surging badly. we have had the codes run twice.
the first time it had: P1693,P0562,P0575,P0237,P0217,P0112,P1488,P0606, and P0342.
we checked the voltage at all of the sensors and did have 5 volts everywhere,cleared the codes and checked it again
the second time it had
0122,P1693,P0118,P0112,P0342,P0117,P1488,P0606, and P1295.
any info would be greatly appreciated as we are mechanicaly inclinded but fear electrical problems. could this be an ECM or is it maybe a sensor?
the truck also had a power puck installed 6 months ago could this have caused any of this?
