C5 2.0 Hpi Anti Pollution System Fault (yet Again)

[Guest Oiltech]

2002 C5 2.0 HPI exclusive SE, 63,000 miles - Anti-pollution system fault displays every time engine is started, warning light remains on, all the time.

 

Fault codes P0304 cylinder 4 misfire and P1336 Catalyst aging show when diagnostic checked - unable to reset faults. New spark plugs fitted but no change.

 

Engine has developed a fault during the last couple of weeks, it revs freely through the range under load without misfiring. It was occasionally hesitant if pressed hard during accelaration prior to plug replacement.

 

Previous hassles - VTC hub replaced at 40,000 miles, High pressure fuel pump at 51,000 miles and EGR valve at 53,000 miles.

 

Unreliable engine spoils an otherwise good spec. car.

 

Any advice or suggestions what to check would be appreciated, have access to TEXA IDC3 diagnostic equipment.

the P1336 is your problem.

P1336 Crank/Cam sensor range/performance

S2000PM1/2 - High misfire on several cylinders

For TU5jp4 with ME7.4.5., check for Compression faults. I have witnessed, on more than one occasion, burnt exhaust valves
