ECU codes - need help

Recommended Posts

Hi peeps. I got a 85 EA82T with the ecu codes 12 and 33. I know these stand for -starter switch off and - coolant sensor or circuit. The car has been running rich lately. Is the first code normal? What does it mean? And just to confirm is the coolant sensor the one near the radiotor top hose and aav or is it the one inbetween that and the knock sensor. I know both measure temperature but i get confused :confused:

Its the one by the knock sensor. Contacts get dirty sometimes, so try cleaning it first. It would definitely cause you to run rich.
