    Just like the title says. Shop says to get at it they have to pull both seats, the floorboards and the doghouse to get at the sensor on the rear of the motor. True? Anybody know?
    @Goodysnap @nasriza Any ideas? Company truck but I drive it. Check engine light with this code comes on. Then goes off for from 10 to 200 miles, then back on again. Over and over.

    The inlet Nox sensor is mounted at the rear of the engine. Most trucks you are able to turn the steer wheels all the way to the right, remove the left side inner fender, squeeze up in there and reach up to unbolt the sensor. There are a couple of zip ties at the back to cut too. Then turn the wheels to the left, remove the right side inner fender and you reach the rest of the zip ties and remove the sensor end from the outlet pipe.
