Map Sensor Different For Motorized Throttle Body?

[sifaan]

Hi

 

I have a permanent fault on the MAP sensor (full details below) - even if I clear it with Diagbox the fault reappears.

 

Do I need a new map sensor? according to service.citroen.com (checked a while back) the part number is 4574.03, however there is a similar part 1920 AK - which if I recall correctly is the sensor for the manual throttle body (mine is motorized throttle body)

 

However, when looking for parts on ebay, the sellers seem to consider both of the part numbers as identical. Are they?

 

btw the number on the existing sensor is 96 394 188 80 although I don't know if that is the original sensor or if it was replaced (correctly or incorrectly) before I bought the car

 

One reason I hadn't changed the sensor was that some years ago the agent here said they tried it with a sensor off another C5 and still the fault didn't clear and so I thought perhaps the fault was with the harness (but the engine harness was changed a while back to no avail).

I doubt if the mechanic who did the testing would mix up the 2 versions (if they are different) because he was the one who first told me of the motorized throttle body and its differences.

 

Thanks
