Just changed the camshaft sensor and now my tow/haul is flashing. I’m not sure what to do next.
Do you

Hi,

Which sensor was replaced? Was it on the left or right side? Also, did you check fuse 2.24 in the central junction box? It powers the tow/haul switch. See pic 1 below for the location.

When testing it, first confirm the fuse is good. If it is, confirm there is power to it. Here is a link that you may find helpful:

Let me know what you find. Also, let me know if you disconnected anything other than the CMP. I looked through the wiring schematic and noticed many wires near or around the cam sensor at the PCM are tied to the transmission.

Let me know.

Take care,

Joe
