Thread: DRD MM3 Questions

    Re: DRD MM3 Questions

    Have a you tried any other type of reader such as the AlfaOBD app?

    May be a lot cheaper then buying another tuner?

    Not so if that would 100% give you the answer though but it might be worth a shot?

    I'm having the same issue you are with the service electronic throttle control light.

    My truck is a 18 2500 with the 68rfe running mm3 and DRD tunes.

    I let my truck idle for 15 minutes yesterday morning to warm up and about 20 minutes after I got on the road i got the service elec. throttle control message on the dash with the red lighting bolt and check engine light.

    I check the DTCs in the tuner and there no codes for the elec. throttle but I did have a P0335 crankshaft position sensor performance.

    Are the two issues related?

    This is the second time Ive had this problem. Maybe @DRD can give some input???

    It's likely the crankshaft position sensor is the culprit since you have a code for it.

    The service electronic throttle control message can show up due to a number of failed sensor inputs from the actuator throttle position sensor to the MAP sensor.
