Hi people. My RCZ is the garage again. Just had a call from them to say there are error codes.

P 1655 - engine running system info - short circuit to positive

P1656 - engine running system info - short circuit to earth

P023B - control of coolant pump actuator - short to earth

P023C - control of coolant pump actuator - short to positive

There came up after working on cam timings and replacing cam cover gasket.

Anyone have any idea why this might come up?

Many thanks, Ben

I can only find 2 which give a indication of power loss for Peugeot Generic codes
P1655/1656 Starter Disable Malfunction
023B/023C Turbo(TC) Intercooler coolant pump circuit low
Does the car start or turn over? has the ECU poor communication for the timing parameters ?
Check condition of Battery ? Maybe a connection issue ? Short to earth ? short to positive? BSI no signal recognition maybe a power drop off wiring harness Engine ?
Starter system fault can be attributed to = Battery?Alternator? Starter Motor?
No disrespect to the Mechanic but is the Timing set up correctly ?
