Code 528 and 542

[Stracey R]

Its been about a week since I had last driven my sho. So I decided to check codes after driving around, it drives fine and all. I have two codes:

528 System shows voltage at pin 10(is A/C on?). It wasn't on.

542 Fuel pump open, bad ground or always on.

Is my fuel pump on its way out? It sounded fine when I did the eec test.

Anyone had these codes before? This is the only codes that had showed up for over a year.

Thanks

If the climate control is in any position other than off, you will get the code 528. As far as 542...have you stalled the car recently?

I guess I can disregard the 528, come to think about it, I did check the temp outside using the eatc.

For the 542, my sho cranked a bit longer than usual, could that be it? I never stall an mtx sho .

Both of those codes can more or less be disregarded. I would clear them, then do some spirited driving and check again. They will probably be gone.
