Hello, my name is***** and thanks for your question.

Have you had it scanned for codes yet? Does the engine and transmission operate normally when the light comes on?

a scanner I don't know what you mean by generic
Expert:  Kenny Z. replied 2 months ago.

Is it a small hand held code reader like autozone sells?

Expert:  Kenny Z. replied 2 months ago.

Ford has many proprietary transmission, throttle body and PCM codes that can only be read by high end scanners such as Ford IDS, Snap on SOLUS etc... the auto parts store code readers will not pull these codes.

this is a actron a yellow scanner you plug in
Expert:  Kenny Z. replied 2 months ago.

Yes actron will only read generic OBD2 universal codes. Looks like you are going to have to have it scanned with a higher end scanner. Sorry please don't shoot the messenger.

that's ok the wrench came on my lights suddenly dimmed and had it checked and the voltage regulator was bad changed the altenator but the wrench came back on
Expert:  Kenny Z. replied 2 months ago.

I would suspect it is going to have one or more of these manufacturer specific codes. They really go all out sometimes with these codes, making you take it to the dealer! There are several high end scanners that aftermarket shops use, cheapest one is over 2K.

basically you cant tell me anything at all what are the common problems stemming from the the wrench symbol
Expert:  Kenny Z. replied 2 months ago.

Gas or Diesel?

Customer: replied 2 months ago.
Expert:  Kenny Z. replied 2 months ago.

Intermittent output shaft speed sensor failures, Intermittent transmission range sensor failures, Internal PCM torque calculation errors, Internal PCM engine timer faults, Intermittent high speed can buss errors. Next to impossible without codes, these are the most common that I see at the dealer. There are also many diesel specific codes that the actron won't retrieve either, catalyst, dpfe, regen codes and the like are all manufacturer specific.
