12561211 Camshaft Position Sensor Compatible with 1999-2006 Chevy Silverado Tahoe Express Suburban GMC Sierra Envoy Yukon Savana Cadillac Escalade Hummer H2 Cam Sensor Replaces PC273, 917-715

I'm not sure what I would be writing if it DIDN'T work. Just finished a Gen III LS engine rebuild 500 miles ago - everything works great, including this cam sensor.

So far so good. Fit perfect

It doesn't work all times have to crank at least twice to start, will kill my starter, definitely going to replace with OEM, not trusted, look at others,skip,

Good match to the oem part. Only issues was when I was installing it i didn't have it all the way down before tighting the bolt and bent the metal bracket. So I ended up not using it. The oring may have been to big.

It works fit right in nice and tight like the old one replaced it while doing knock sensors but with 300,000 miles more stuff broke while fixing it so this sensor is definitely worth the buy

Just as good as original

This sensor fixed my check engine light and helped the vehicle to start faster. It was slightly difficult to change because of the location on the engine but this was the first time it ever had to be done so that is good. If I ever have to do it again, I know how its done so it should be easier.

Didn't even clear the check engine light now my car shows high output from the sensor doesn't even work right
