Using the little wires as probes works OK. I've found the best device to use is a wire piercing probe for a multimeter. The probe inserts a tiny point through the insulation and holds itself in place via an internal spring.Originally posted by ddt90GL@Sep 7 2004, 07:17 PM
I had a similar problem with my 1990 wagon and found the information below from an earlier post:
I know that the max is 5V and that when fully closed it should be .92V to .98V
If it functions within that range when you operate the throttle it's fine.
when not touching the pedle the voltage was .92543V and when wide open throttle it was 4.6075V
I plug a couple of wires in the electrical connector and check the voltage at idle and at WOT and I got very similar to the above numbers. I re-run the test and just pressed the pedal harder and the code is not there... but the MAF code (74, I believe) still came out :huh: . That was a while back.. I should try it again.
