My Canyon Duramax is 2-1/2 years old, and at 43,474 miles I took it into the dealership, as over the past week I kept getting a "Reduced Power" warning in the DIC, followed by the "Check Engine" light on some occasions.
The dealership ran diagnostics on the truck and came up with a P041D & P041E Exhaust Gas Recirculation Cooler Temperature Sensor - Position 1 failure. For Diagnostics test and replacement they wanted $560... to replace a sensor. I declined the service, after dealership stated it wasn't covered under warranty, so I could inquire with GM as to why this part, which I assumed was associated with emissions, was not covered under warranty. GM stated sensor was covered under the 36,000 Bumper to Bumper warranty, but not the 5/60,000 Power Train, nor 70,000 emissions warranty.
With that, I decided to look up the cost of the sensor online. If I'm correct, it's GM Part # 55488437 and can be delivered to my door for $48, if it's the wrong one, then the rest are cheaper!
There are two sensors associated with the EGR Cooler - Position 1 and Position 2. I'm going to assume that one is at the EGR, the other is on the exhaust. Can anyone confirm for me that the sensor pointed out by the arrow in my picture - located along the back side of the engine, driver side, near the oil stick - is actually Position 1? I'd much rather replace myself for $48 than pay dealership an astronomical price to replace.
