🚗 GM Original Equipment ACDelco Exhaust Particulate Sensor - 55502921 Review

There was a code p1478 for 18 Chevy Colorado Duramax. This is an exact factory replacement for the particulate matter sensor and costs half what the retailer charges for the part. The delivery was incredibly fast. They sent it out on Monday and were already at my door on Wednesday! 100% satisfied

OEM replacement for Colorado/Canyon Duramax. Quick and easy installation using just two 10mm screws, two plastic wire clamps and the sensor body itself (you'll probably need a box wrench and hammer). It even comes with anti-seize already on the threads, although we'll see how much of a difference it makes in the long run.

I've waited a bit to write a review but. Not sure but when I installed and ran Regen and looked at the options it seemed to work but the Check Engine light and the same code kept popping up. So I'm not sure if it's a sensor as the readings come after a minute or two and are negative at first and alternate between positive and negative readings.
