Hi there vass
I don't think we have a MAF fitted to the V6, it's the MAP we have, got this from a web site "making sense of sensors"
MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR. This sensor is mounted on or connected to the intake manifold to monitor intake vacuum. It changes voltage or frequency as manifold pressure changes. The computer uses this information to measure engine load so ignition timing can be advanced and retarded as needed. It performs essentially the same job as the vacuum advance diaphragm on an old fashioned mechanical distributor.
MASS AIRFLOW SENSOR (MAF). Mounted ahead of the throttle body on multiport fuel injected engines, this sensor monitors the volume of air entering the engine. The sensor uses either a hot wire or heated filament to measure both airflow and air density.
Its the air temp sensor that I had disconnected,not the MAF or MAP.
The car is coming up for it's MOT on the 14th of feb so I took it in today to see if the emissions were ok, maybe this would point to a bad lambda sensor if it failed this test, everything checked out ok
lambda min limit 0.970 max 1.030 actual value 1.002
HC ppm was 4, CO was 0.008 fast idle test
Natural idle CO was 0.005
I am at a loss with this one, and so are Renault, Mr computer is not giving them any fault code's, so all they can do is start chucking parts at it :crazy: .
So I will have to look for a good local diagnostics center.
I asked at the MOT center if they could recommend one
they did'nt seem to have a good word for any of them around here, "sure they have the diagnostic equipment but they dont know how to use it".
Well at least it passed the MOT
