Help Please!

Under the hood of my 96 Firehawk, inside the relay box, there is a fuse that says "Engine Sensors". This fuse keeps blowing out and my Check Engine light came on. Went to check which codes it was throwing and it says the MAF and P1657 codes arbeing thrown. Since it a T56, my reverse is really hard to put in. I know i have a short but don't know where to start. I do have the skip shift eliminator, but thats the way i bought it. ANY HELP IS APPRECIATED. THANKS

Re: Help Please!

All 4 O2's, MAF, the reverse lockout solenoid and the skip shift solenoid are on that circuit. You should try disconnecting all the items listed and the tranny and then see if it blows. If it does you have a pinched wire. You can find it by placing an ohm meter in the fuse panel on the side opposite the 12V contacts at the fuse. That is, one side of the fuse has 12 volts and the other side goes to the devices in question. It this side you want to check. Set the meter for low ohms or buzzer. You will now check from the contact to ground. If a wire is pinched to ground, the meter will read low ohms or buzz if you set it there. Now wiggle the wires until you hear the meter stop buzzing or go to infinite reading.

Re: Help Please!

I neglected to mention that you have to remove the good fuse before you do the test. So how did it go? Did you find anything?
