Engine fault codes
Hi Guys
I wonder if you can help me
I have a 2016 Z51 with 17k on the clock, the only mod is corsa axle backs with nnp
I just got the car out after winter and have the engine management light on.
Took it for a drive to see if they would clear, car runs perfectly
Plugged in an OBD reader and it says there are 3 fault codes
1: P2635 Fuel pump A low flow/performance
2: U0074 ISO/SAE reserved
3: U18A2
Any thoughts?
Ian

U0074 and U18A2 are both data bus faults. U18A2 is specific to the fuel pump driver control module.
Is it possible a rodent might have nibbled on something in the harness while your car was laid up for the winter?
