On my 04 Envoy, I've been getting a C0055 code on my Bosch scan tool. It says the MIL is requested - but it has NEVER tripped a light. I don't believe I have any other symptoms (though I may be mistaken - it's had this code since I bought the vehicle).
I decided to probe further - using my scan tool (and under the ABS PIDs), I checked the FR and FL wheel speed and both are equal and accurate to the speedo while driving. The rear sensor always shows 0KM/hour. I am assuming this is not normal?
I was looking on the forums and I've found a lot of information pointing toward the rear prop speed sensor (or wiring) on the passenger side rear of the transfer case - but not the actual rear wheel speed sensor (I'm assuming there is one on the diff somewhere? I haven't actually looked yet). Is this sensor on the transfercase the correct 'cause' of the code?
