ACDelco gm original equipment 213-1557 engine camshaft position sensor

It’s a very good product and solved the problem of code P0340

Excellent, works stable and fit 👍 perfectly

Arrived promptly and installed easily. I had a local shop replace the cam position sensor on my 2002 Envoy in 2014. The oem part lasted 12 years and 100K miles, but the non-oem part the shop installed only lasted 2 years and 15K. So, now knowing the symptons and the part needed, I replaced it myself after checking a couple of youtube vids showing how, only I went back to the part that lasted 14 years; oem. The part I received was indeed ACDelco. A word of advice... All the vids show removing the wire harness from the cam sensor before removing the part from the engine. If you've done this (or are attempting to) you'll find out pretty quickly that the position of the connector makes it very difficult to figure out how to do that. I soon realized that I have plenty of harness to detach the part first, then flip it over to see the connector and then remove it. Do the reverse when you install it and you'll be done in 10 minutes, total!

PRODUCTO ORIGINAL

Tenía la idea de solo hacer el cambio de sensor y eso solucionaría el problema...en mi caso,tuve que llevar a programar el sensor para que funcionara de manera correcta.Lo menciono por si a alguien le pasara lo mismo pensando que el sensor no funciona bien

First, always research your 'part number, maker and auto' for compatibility. This is an AC Delco part (made in Mexico) and fits '02 Trailblazer (and other '02 GM Variants). Installation is not hard 'however' some points. 1. The wiring harness, especially in high mileage, never changed autos, can be a son of a gun to 'unsnap'. The grey plastic piece that resides on the under side of the snap has to be 'slide' towards the front of the car/you, then you can depress the 'squeeze release' part of the connector and pull off the plug. Mine was hard to pull off and having a 'bent' blunt small object to push into the small opening to depress the release is helpful) 2. Once the plug is off and pushed out of the way, use a 10mm socket and small ratchet to undo the bolt. It is a fine threaded bolt and will take some turns (and a LOT of turns to screw back in as well!) to unloosen. 3. The sensor will come straight out but slightly applying a wobble tug will help and if it has never been changed can be sluggish. 4. The 'new' sensor should have a bit of 'new oil' slightly applied around the neck near the blue o-ring. Not sloppy amount, just a film. 5. The 'new' sensor will POP in... with an AUDIBLE snap sound. I have never not experienced that so beware, it will pop in, you can feel it. 6. I cleaned the bolt, put a tiny film of antiseize on it and screwed it back in, and screwed it and screwed it... finally takes up! 7. The harness/plug only goes on one way, don't force it... see the alignment and push onto the sensor's connection. 8. Clean off your work area, start the car. My 'check engine' light went out on the third restart... which is common. We noticed a distinct difference in 'engine' smoothness, in shifting and ever so slightly in throttle response. YMMV. Part does what is says it does. Do your research first, make sure this one fits YOUR car/auto.
