June 5, 201015 yr I'm trying to get rid of the P0106 code again. That CEL is starting to get annoying. Anyway, looking in the FSM the very first step it asks for transmission type AT or MT. For MT is says to "Check AT/MT identification circuit. <Ref. to [T11BN0].>" I can't find that section in the FSM, but I'm pretty sure I read that the MT ID circuit is only a pin to ground from the ECM. I think I found it in the wiring diagrams. Looks like pin 50 on B84 which goes to ground on connector E3. Can someone just confirm that for me? Or point me to the right page out of the FSM? The other thing I'm trying to find is a vacuum hose routing diagram for this car, which I would think should be in the FSM, but I can't seem to find that either. I think the one I got is missing a few (hundred) pages. The one under the hood is not the one for this particular car. This is a 96 2.2 MT, no EGR.
June 5, 201015 yr Author what is the P0106 code? MAP/Baro pressure sensor circuit range/performance I've just dealt with the CEL for the past 6 months or so because it doesn't seem to affect driveability.
June 5, 201015 yr I guess you cleaned it and then swapped in another one to see what happens? You cleared and it came back? I've heard of MAF/O2 sensor codes being related. I can't recall which way it is and I haven't seen it yet but I've heard folks that say they either have a MAF code that goes away when the O2 sensor is replaced or an O2 sensor code that goes away with MAF sensor replacement.

Have changed it twice and no change, also changed out the switching solenoid with no change. I'd like to check that my vacuum routing is correct, I replaced all of the hoses in that area (which are really the only vacuum hoses on the engine) and I'm 98.76483% positive I put them back correctly, but I'm kinda wondering if the reading is fluttering a bit because it feeds off of the number 3 intake runner, and confusing the sensor. I may switch that to the port by the throttle body and see if that changes anything. edit: also went checking hose connections again earlier today, and found traces of fuel in the FPR hose... AGAIN!
