TEST5 Air flowmeter
Damage to electrical components
Visual inspection: remove the flow sensor - the components should not be broken.
Replace the air flowmeter if necessary.
Oxidation of the electrical components
Visual inspection: remove the air flowmeter, there should not be any greenish deposits on the electrical
components.
Replace the air flowmeter if necessary.
Clogging of the air flowmeter
Test:
– Check the values for conformity:
– During the first 5 seconds after starting,
–PR064 Coolant temperature: 80°C.
–PR055: Engine speed: idling.
–PR059: Air temperature between 30 and 70°C.
–PR146 Inlet air flow: between 20 and 28 kg/h.
–PR220 EGR valve OCR*: between 22 and 30%.
–PR132 Air flow: between 20 and 28 kg/h.
–PR051 EGR valve position feedback: between 22 and 30%.
–PR023 Air flow difference between - 50 and + 50 mg/stroke.
– Apply the procedure for DF056 Air flow sensor circuit for the checks on the air flowmeter.
Replace the air flowmeter if necessary.
