Nice gloves…
was the check engine light on ?
I was surprised at now Check Engine Light too. The sensor was bad enough to
reflect a legitimate cold temperature, but not so bad that the computer
detected a bad sensor. I think at the time I measured the sensor and it was
reading 30 deg C lower than the real temperature, not like 100 dec C lower.
I’m surprised there was no CEL to point at the problem. When my son’s Jetta
had a coolant leak I got a temp sensor code, but fixing the leak solved his
problem. Both cases nicely show that there is still room for clinical
diagnostic skills to guide management.
nope. my guess is the sensor output was within tollerance but was simply
reading very low.
One of them acutally goes to the gauge and only has one wire. The ECTS has
two pins/wires.
Your’e right. All of the S “2” series were the DOHC.
Thank you so much you saved my car….soon as the parts store opens up im
going to buy this part
If it’s an SC2, it has DOHC
Couldn’t understand a lot of this. Your mouth was too close to the mic
