99 E300 Turbo Obd Ii Codes
I may have done some damage this time??? I was curious to see how the egr solenoid was working with respect to throttle position. I was testing the plug with two wires that go to it with my test light. Whe I was on the positive lead with my test light in the plug I reached over to move the throttle and the test light just nipped ground. There was barely a spark but the light went out and never returned. I should have been using my volt meter!!!
The check engine light illuminated and I read three codes: P0100 - Mass air flow circuit malfunction P0243 - Wastegate solenoid P0400 - Egr flow I believe the wastegate and egr solenoids are on the same circuit and I guess the mass air flow too. I am wondering if I fried this circuit in the computer? I do not think there are any fuses for this sort circuit is there? I was under the impression it all ran through the computer. I did clear the codes and they just immediately come back. The car runs ok with the exception of lack of power which I know happens when either the egr or wastegate codes come up. Does anyone have any info on this? I am thinking at the worst an engine computer and maybe the MAF and solenoids. Thanks!

why don't you start with the simple stuff and check all of the fuses. There are 3 fuseboxes on your car, check them all for a blown fuse.

Thanks Marty!! I was pretty sure the fuse box under the seat was not related to this issue and I checked the fuse box on the driver side. When you said there was three, I thought I guess there is one on the passenger side with the computer.
A 10A fuse was blown and all is ok. Thanks again!!

No problem...virtually every circuit is protected with a fuse...the challenge is finding the right one.
