CEL today..Camshaft position sensor
I had a Steady CEL light today which the SECS reported as P0340 (Camshaft position sensor circuit malfunction).
Driving into Middlesborough on the A66 (not a dragstrip at that time in the morning) and the car seemed to hesitate / get bogged down for a second. CEL came on and the SECS reported the above fault. After a couple of miles the SECS reported no faults but recorded the P0340 as Historic.
The CEL light went out after some gentle driving.....and now the car "seems" back top normal.
The cars has been a bit "off colour" for the last few weeks, nothing I could pinpoint, but just wondered what the fault meant ???
Replace the camshaft position sensor ??
Thanks in advance

could be the sensor has started to die, and in doing so given an error,,,
poor starting will be the long term issue.....
take the sensor out and clean it,,, a s/h one is about 35 ish from grade a
it could also be a loose connection or wiring fault in the associated circuit

I ve put a post in drivetrain and all I found out was a sensor is £60 second hand, but I don't want to do this as mine has only lasted 20k miles

Thanks Mart
....I was worried that it might lead to my engine going bang like a failing MAF !!
WRX Rich
......I'm on 21K miles so not sure what to do, I'm glad is that it's not going to lead to imminent meltdown and vast wads of cash. I might get it replaced just for peace of mind.
Thanks guys

Thanks again
I'm going to get the dealer to look at it. The ECU has now stored the code as historic (according to the SECS) so the dealer should be able to see it with select monitor. I thought the newer MY02 with the radio ariel in the rear screen etc. had a newer and less sensitive ECU for these sorts of things.
I used to get CEL's with the decat so I can live with them but as this one lit up the car reallly did hesitate, not what I want overtaking an ASDA truck on the notorious A69 so I need to look further. I noticed that the AFR is dipping below 1.00 quite a bit and also wondered if the ITG filter I used to run has gunked up the MAF ??
Thanks again fo all the help

PS I have checked the pink badge and it still has that "Swissol" look D:
