after my first time at a road course, i threw an SES light. after getting home and scanning, it gave me 3 codes: MAF low voltage, skipshift fault, and reverse lockout failure. i needed two hands to get her into reverse, but the rest seemed to drive fine. i have a custom dyno tune, and tuned out the skipshift long ago. i saw it was the ENG SEN fuse, so i replaced it. but it keeps blowing.

so where do i look for a bad/burned wire thats causing this? i checked around the 02 sensors, like someone suggested, but without cutting the plastic mesh, the wires seems solid and unbroken.

anyone have this happen....or any ideas on where to look.

 

bump......anyone, anyone at all? no one has an idea?

 

I'm not 100% positive but I think that fuse may be tied into the lighter fuse as well. See if the cigarette lighter is messed up.

 

The O2 sensor heaters run off this and you might
chase the full length of all four, especially where
they might be routed past the upper / hotter part
of the exhaust manifolds / headers.

 

say i find a burned wire, how do i fix it? do i have to replace the entire thing, or is a splicing sufficient?

 

passenger side frame rails near the headers. You will find some burnt wires. The best bet would be to solder them together.

 

how bad is it to drive in this current condition. ive got an auto this friday, and maybe track day saturday. if i dont find it in time, is it alright to drive/race like this?

 

I just made a thread for T56 drivers..... this was MY solution

This is of course after you are sure there are no crimped/burned wires.
