I have had my toledo v5 2.3l 170 BHP for a few weeks now and the diagnostic warning light appeared on the dash yesterday. When I had the car scanned at the garage the fault code in the system was 17559 (p1151). The garage reset the code and it hasn't reappeared in the 20 mile trip back home? I have found the information on the fault code on Ross Tech. What is the best way to test and eliminate each sensor? The car almost feels as though it has a very slight misfire. It has been like this since day one of my ownership and I assumed it was because of the v5 engine configuration that caused the slight shaking on idle. Is that normal? I would very much appreciate any help on this one!
