Year of Manufacture *: 2007 Engine Size and Code *: 1.6 5fw ( Optional) Fault Codes: dtc P11aa
Had a look at this last week.Customer complaint of cooling fan on all the time,and stays on for around 5 mins after switch off. No other drive-ability or starting issues.My initial thought was coolant temp sensor or related connection/wiring problem.Scanner showed dtc P11aa inlet manifold pressure sensor coherence.On top of the plastic cam cover is a small pc valve that had come apart from the main housing. Luckily I found it laying on top of the air cleaner assy and managed to glue it back in position.It is not available as a separate part, only the complete cam box cover at around £300.Cleared codes and checked cooling fan operation and all OK. So now my question is, how can an manifold pressure sensor fault bring on the cooling fan?Any suggestions?
