"Anomaly on inlet air mass signal. Check following
Sensor power supply(12 Volt from Main relay) between pin 1(+) and 3(-) of sensor connector
Signal emitted by the sensor, proportional to the flow of the engine, between pin 4(signal) and pin 2(signal ground) by means of multi meter.
Continuity and insulation between pins 2 and 4 of the sensor connector respectively, to the ECU wires bundle connector pins 26 and 7
The reason for this fault is that the ECU has received very high signal from the sensor
Does anyone know where I can get air mass sensor connector from?
Ok, finally cured mine.
The main 'problem', apart from diagnosing it, was it had a 'diesel' maf in it!!
Check your maf sensor's Bosch part number, should be: F00C 2G2 030
It also had a TS air filter, at least 1 faulty ign coil & the eml/inj warning led had been 'removed'!! All that kept upsetting our diagnosing.
I sussed it over a week ago but a rear brake pipe had burst beforehand so I couldn't do a proper road test, one mechanic went on holiday & another mechanic, who is mega busy, 'fitted it in' but took from Wed last week until today to replace all rear pipes. Road tested for 20 miles tonight & all's good.
I've got numerous 'old' secondhand mafs which I tried but all were faulty, giving slightly different running misfiring etc. I then swapped with one of my sales GTVs & hey presto!
TSs use the same sensor as do some Vauxhalls, correct sensor is inside this....so I'm told, buying one tomorrow: Brand New Vauxhall Parts | Air Flow Meter / Maf Sensor - 93171356 | 0281002180 - GM Parts Bosch Parts Elring Parts
