Oil Pressure Sensor Switch Sending Unit D1843A 12635957 Compatible with Chevy Colorado Equinox Trailblazer Malibu Impala GMC Envoy Canyon Buick Lacrosse Enclave Rainier Cadillac SRX 12570964

very good product

This part fit perfect for my 2009 GMC Acadia. I removed the oil filter and used a 1 inch extension along with a 3 inch extension coupled with the 1 and 1/16 inch oil sending unit socket I picked up from Advance Auto. It was about 12 bucks.

It seems to be working ok. Had intermittent error code of abnormal oil pressure. After changing this sensor it seems to be working ok.One tip for changing it out. I've seen a lot of videos which suggest to remove the oil filter, and even alternator. But on fact all you need is a very deep socket or you can buy special one from Lisle (13250 IIRC). With it you can just unplug the old sensor, put the socket on it (it's tight, but you will be able to fit the socket between the oil filter and alternator) with ratchet (or breaking bar - mine needed A LOT of torque to break it loose) and unscrew it. That's it. Super simple and you actually don't need to remove anything from the engine. Then just screw new sensor back with the same procedure reversed.One more note - you might run into alternator when unscrewing it. Still you don't have to remove the whole alternator out - you can just unscrew it's main positive line (be sure not to touch the ground with it - otherwise big kaboom :) or even better- disconnect the battery), and unscrew three small bolts holding the side cover of the alternator. With it removed this provides easy access to the oil sensor.

I replaced most of my sensors after buying my used vehicle, to be sure they're all new, so I couldn't say if this is good or not, but the car runs fine so,,,

Device was a correct fit and fixed my issue where the OEM unit failed after 190K miles.

02 trailblazer Oil pressure Guage would drop to zero at idle and it would say shut off engine. This fixes my problem also there was an oil leak from the old sensor..new part came w o ring and stopped the leak

Fits perfect on my 2004 Chevy Trailblazer Ext 4wd V6. Super easy to change out! Great value. Works great!

This fit a 2009 Buick Enclave. It's located next to the oil filter. I bought a Lisle 13250 Oil Pressure Switch Socket to help me remove it. Taking the electrical connection off is tricky, it comes off in a similiar manner as the protective cap that is shipped with this sensor. Used a 3/8th socket wrench with a 6" extension to remove it (counter clockwise), screwed the new one in and tightened lightly, plugged the electrical back in.Worked perfectly, my sons low oil pressure warning light at idle went away. A local mechanic quoted 3.5 hours labor for this, I did it in 15 minutes.The tricky thing about this repair is you can't see anything and have to do it by feel. I watched a YouTube video and paid really close attention to what the guy was doing so I could feel around and recognize what I was touching.I'm proud of myself, and really helped my son out with his "new" car. Hopefully the part holds up for a while, I'll update this review if it breaks anytime soon.
