Engine/Transmission (1998.5 - 2002) Code p1693 and p0380

Does anybody know what these codes mean. The check engine light is on and it sometimes will go off for a day or 2 at a time. Thank you.

The P0380 is a grid heater fault... Possibly a wire knocked off a grid heater relay on the driver side inner fender (beside the power steering/injection pump).

The p01693 is whats called a companion code, Its just telling you that there is a code in the PCM

Best of all, unless you live in the Arctic, it's not a critical code - if the grid heater relay is unplugged - or fails - the ECM senses it's failure, and sets the code - all that really happens in that case, is that the grid heater(s) won't work - not an issue above zero degrees or so...



Probably just a poor relay connection.
