GX460 P0351-398 all coils DTC (1 Viewer)

Hi there,

Driving my 2012 GX460 down the road and it just died. Got it to the side of the road and pulled the codes and have P0351-398 (all 8 ignition coil codes) with no other codes. I'm in a moving transition state so I'm not really in a spot where I can do much troubleshooting... I did try resetting the codes (to no avail) and gave the wiring coming off the coils a good visual inspection looking for signs of rodents (found nothing).

Had it towed to a shop and I put a spare ignition coil in the seat for them to test with... shop says they tried moving coils around with no luck. They say the crank sensor "has no signal" so they have ordered a crank sensor. When I pulled the codes there was no code for the crank sensor which appears to be P0335.

Anybody heard of a similar problem?

Not the crank position sensor... took it to another shop...

Frayed wire leading to the crank position sensor. Back in business

So was it maybe rodent damage to the wire after all? I've been through this with my last 4Runner (rodentia>knock sensor harness).

Tech said it wasn't rubbing on anything and no rodents, looked like the wire got pinched at one point and eventually failed at the pinch point.

May have happened from a previous service/maintenance from a careless mechanic.
