Customer Question
The Service Engine Light...

The Service Engine Light stays on, I get a PO410 code. What do I do to fix this?

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix with a Pontiac. The Pontiac Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.

If I disconnect the ground cable, light goes out, if I connect my diagnostic tool, I can clear the light, but it always come back on after driving a short distance.

Mechanic's Assistant: Are you hoping to fix this yourself?

Yes mam

Mechanic's Assistant: Great! What have you tried so far?

I have been looking to make sure I can get to the pump, I have not checked the check valves yet.

Mechanic's Assistant: Is there anything else the Pontiac Mechanic should be aware of about your Pontiac?

Not that I know of, but it has a cat back exhaust, it still has catalytic convertors on it.

I see, thanks.

.

There were some issues on them, (a factory service bulletin). Do you know if the AP-FAN fuse is good in the under hood fuse block?

.

If you accept my additional service request for your email address, you can give me your email in a private info box and I'll send you the bulletin and the test instructions in a PDF file, the file is rather large.

You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it, Thanks
