Customer Question
I have a 2008...

I have a 2008 ford explorer. It is hesitating while accelerating. I thought it might be the transmission. But it threw a p0621 code (generator lamp malfunction) I've checked most of the wiring and it seems ok. Made a few repairs to wires. But is still doing the same thing. What should I do next?

Mechanic's Assistant: How old is the transmission? Have you checked the fuel filters?

The transmission has 232000km. I have not checked the fuel filters yet.

Mechanic's Assistant: Are you fixing your Explorer yourself? What have you tried so far?

I'm trying to do it myself. I have checked most of the wiring tested battery and alternator. Cleared the p0621 code. And reset the gpu by crossing the positive and negative cables. The code stayed away until I passed another vehicle. It works ok as long as I don't try to accelerate to fast.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I don't think so.

the first thing to do is replace the generator the internal voltage regulator is failing to and supplying the incorrect expected voltage during the accelerating event and the PCM is seeing this and turning on the light.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
