yea but we swapped the fuse on jeffs car and it blew again, as well as the code came back after i cleared it. i think theres a short somewhere, let us know if the fuse blows again

i had a major short a while back, mice chewed like 10 pcm wires and they were all touching each otherstill ran surprisingly

How long did it take to blow the fuse again?Originally Posted by QwikGT

not long, it varied a lil, once right after a 5 minute drive, once after a startup, once after a 45 minute drive. hopefully gettin the problem figured out next week when i bring it into the shop for the meth, and tuning and ****

Good luck with it man. Can you explain to me what Meth injection is? Thanks

Fixed mine, performed an ohms test from MAF signal cable to the PCM pin, couldn't get a constant reading on it.
Spliced in a new wire off the wire that runs out of the harness directly to the connector. All is good!

Congrats on fixing it. Could you be a little more specific on where exactly you spliced the wire? You made a new wire all the way from the PCM to the MAF? Thanks

Using this diagram..

Looking down at your PCM, disconnect the top wiring harness.
Remove gray plastic clip, just squeeze the sides and pull off.
From there you can unbolt the adapter from the PCM and pull it out.
There you will have access to the pins.
Look for the pin labeled "69". It will be between another yellow and blue wire.
Use a multimeter and set to ohms resistance.
Disconnect MAF connector and probe yellow wire from MAF connector to pin 69.
Try moving the connector and harness while you test to see if ohm reading changes, anything below 5ohms constant should be good, in my case when I moved the connector it spiked to over 100 and would fluctuate.
I cut the yellow wire on the outside of the harness. leaving about 2 inches from PCM harness and routed a new wire up to MAF connector.
