History codes


Recommended Posts

I need some assistance with history codes I am getting on my '97 DeVille with 169K on it. I purchased a 1997 Tech 2 Reference Guide off E-bay last year, and none of the categories let alone specific codes are even listed in the book. Anyway, the history codes I am finding on a recurring basis are: PCM P0603 and P1810, TCS 1255, and PZM B0533, B1552 and B1558. I know one of them is tied into a short I have in my fuel tank sending unit, cause it only appears when I have less than 5 gallons in the tank and the fuel guage starts jumping around. Thanks for any help anyone can offer.

Well I know I just went through the B0533 in my wifes car. It was the fuel sending unit. It is the part in the tank that has the plunger on it. I replaced that, and that code was gone! Now, if yours is a history code, maybe it was replaced already?

Either way, good luck, and keep smiling......

I almost forgot....

You can look in the archives for these codes. That is where I go, and you will see the answers you are looking for.

Just make sure you request more than 30 days worth!!
