End of test

2182

The air mass measured by the hot film MAF sensor is too high. / The cycle duration of the HFM signal is too short. (P0101)

Possible cause:

- B2/5 (Hot film mass air flow sensor)

Affected functions:

- Engine diagnosis

-------------------------------------------------

Test 1: Check component B2/5 (Hot film mass air flow sensor).

1. Check component B2/5 (Hot film mass air flow sensor).

Test 1.1: Check signal of component B2/5 (Hot film mass air flow sensor) via actual value with engine OFF.

Test 1.2: Check signal of component B2/5 (Hot film mass air flow sensor) via actual value with engine speed greater than 3500 rpm.

Test 1.3: Check reference signal of component B2/5 (Hot film mass air flow sensor).

Test 1.4: Check power supply of component B2/5 (Hot film mass air flow sensor).

1.1. Check signal of component B2/5 (Hot film mass air flow sensor) via actual value with engine OFF.
