View Full Version : Anyone with a Fault Code scanner want to come over to my place??

My car is idling rough, misfiring, and doesn't even drive down the street anymore. I'm stumped as to what it is and I've checked all the usual, so I need to borrow somebody's fault scanner tool for a few minutes so I can get a better idea of where the problem(s) are. I suspect I've got either a clogged injector, dying fuel pump, or possibly a blown cylinder or valve. For some reason though, my car has NEVER been able to do the pedal test for fault codes, so I need to borrow somebody's scanner tool. If someone wants to pay me a visit any time tomorrow, or on the weekend after 1:30pm, that'd be awsome, I could really use the help. I'm also free monday through wednesday as well.

thanks a million!

I could probably do it on Sunday if you can wait till then.

I have the Peak Research Tool thing, that'll do the trick, right?

Try the pedal test again. Your car is a '94 .. so you'd have Motronic 1.3 - 2.0 on your car.

The fault codes for these systems will appear on the check engine light when you turn the ignition key to the On position (but dont start it), then: fully depress the accelerator pedal, then fully release it. Repeat the depress,release cycle 5 times fairly quickly, but not too fast. It should be completed in a few seconds. What you are doing here is clicking the wide open throttle switch then the idle switch each 5 times. This signals the Motronic unit to send the fault codes by flashing the Check Engine light. You should see the light flash once then it will start flashing the 4 digit codes. If there are no faults, you should see the 1444 code (and 2444 if you have a 12 cylinder). The codes appear as a series of flashes for each digit. The flashes indicating one digit are about 1 second apart, the next digit appears after a couple second interval.

In 1995 the Motronic 3.x fault codes were implemented. The fault codes were on the check engine light but the the timing with which you turn the key then depress and release the accelerator pedal is much more critical. You have to depress and release the pedal 5 times, rhythmically, but much faster than for the earlier system. It usually takes a few tries to get it right.

Thanks justin. I've done the test on several e36's before, but for some reason my '94 325is just wont do it, no matter what. Oh well, koncise, pm me your number, and I'll give you a call sunday when I get home from work.

thanks man

Disconnect battery for a few minutes.Reconnect it and depress accelerator pedal 5 times within 5 seconds.This helps sometimes.

just an update, the car is back in action *th-up*
During my troubleshooting process, I managed to do a pressure test on each of my cylinders (which I've never done before). Each cylinder came back with a reading of about 195psi, but this was while the block was cold. I suspect my instruments for testing compression aren't the greatest and might be giving less-than precise readings, but at least I got to see that the psi was consistant over all 6 cylinders, so I know I didn't blow anything up yet :D
