Exhaust code

[Chiefcheese]

Anyone get one of these codes? I checked for corrosion and any open wires but didn't find anything conclusive. Capacitor change perhaps? Pulls barely 7800 so the valves are not opening. Had the valves out and they move freely.

I’d check all wires and connections, wiring to ev actuator , etc

Got more too. May need to seek Digital Wrench.

With the amount and variance of codes, it's possible the PWM converter is shot. Good choice on looking for a Digital wrench hookup.

I have read about this. Can you just replace and be fine or ?

 

[Ru4real]

This is purely a guess. I think you can replace it and go, based on other PWM stepper motor applications I'm familiar with.

I have a appointment at my dealer to check on digital wrench. Will update when I know more.

Ended up as the relay that is for the valve actuator circuit failed....actually had low voltage for a while which gave the dealer fits until it finally gave up the ghost. I am going to stock up on relays and capacitors. I think the factory got a little cheap on the parts.

Good info.
