Customer had his 2011 Chevy Malibu towed to PHAD from 4 hours away because his Parts Cannon is OUT OF AMMO!
This Chevy INTERMITTENTLY goes into REDUCED ENGINE POWER limp mode...but I CANNOT recreate the customer complaint...It runs great!
The P0641 - 5V1 Reference Circuit DTC is a big clue...
My gut tells me a harness is rubbed through, but locating the damaged harness is easier said than done!
How do we attack this INTERMITTENT problem in the shop?
