Codes 14 and 41
Long time lurker, new time poster here.
Posting today cause I can't seem find the answer to my particular issue. To start with, I have a '92 V6 2wd DLX p/u. About a week or so, I noticed that the check engine light came on for a few seconds then turned off. It came on while I was decelerating; I believe I had my foot on the gas slightly. When I pulled codes, I had:
Code 12 - Engine revolution signal missing
Code 14 - Igniter signal to ecu missing
Code 41 - Throttle position circuit fault
Since I didn't notice any drivability issues, I figured it might be a glitch, reset the ECU, and didn't think about it.
However, today I noticed the light came on again. It was a similar situation where I was decelerating and might have had my foot lightly on the gas. Pulled the codes again and I had only 14 and 41.
Only other information I can provide is that I did, at one point a long time ago (~year or ago), play with the TPS when I was trying to figure out an idle issue. (Ended up being the intake hose had a crack letting in unmetered air.) So it is possible that it is a tad off, even though I did use a voltmeter to set it as per some instructions I found online. This might explain the code 41, but I can't see how it relates to code 12 or 14.
Is there a common wire/ground shared by these particular circuits?
Thanks for any insight to this situation.
