Hi Guys and Girls: I recently changed out the timing chains, lash adjusters and rockers on my '05 GT. Everything's hunky dory, except that it's throwing a PO198 code; Engine Temp. Sensor High Output. I replaced the oil sender, which is also the sensor, I think, but it's still throwing the code. The sensor' s located on the oil filter adapter. Has anyone dealt with this? Any help would be appreciated. Thanks.
