Check engine light came on this afternoon with the follow 2 codes.
(17) Engine did not reach operating temperature within acceptable limits. Engine does not reach 20║ F. within 5 minutes with a vehicle speed signal.
^^^^First time I've had this one. Not sure what it means but the engine temp. looks all normal to me.
(31)An open or shorted condition detected in the A/C clutch relay circuit. Insufficient or excessive vapor flow detected during evaporative emission system operation.
^^^^The A/C has been taken out of my rig. Again, first time I've seen this code pop-up.
Thanks for any feedback.
