Codes

[BIG JOE]

I checked for any codes this AM. Found 2, 1391 & 1393. For the life of me... I cant find my Code List. Can Any of you tell me what those codes are. I checked the Wiki.. Not listed.

TIA

Truck is running fine tho....

Thanks "stroker". Sounds like it's time for a new GPR (?). Got new Batts. No other indications of electrical issues.

Any other comments ? before I go get a new GPR ?

You can test your GPR to see if it is the culprit rather than just throwing parts at it.

Okay, whats the procedure ?

My thinking on it would be: It's 5+ years old, lots of cycles/starts, prolly tired. But I'm alwayz open for learning something.

At five years old and if it is still the original then you are probably correct in assuming it is the GPR. If you want to check it you can cycle the key and check for voltage across the large terminals on the GPR. If you have 12V on one side and nothing on the other..... bad GPR.
