DTC P0102 Mass Or Volume Air Flow Circuit Low Input: FAILSAFE
- Air flow meter: Engine load is normally calculated by manifold pressure and engine speed; however, calculated only by manifold pressure.
- EVAP cone, learning (fuel): Not allowed to learn.
- Knock compensation:
- At normal: learned ignition timing value = knock F/B timing value + whole learning timing value + partial learning timing value
- At trouble: learned ignition timing value = -3°CA (retard 3°CA)
- Knock F/B timing value = 0°CA
- Whole learning is not allowed.
- Partial learning is not allowed.
- ISC control: Make the open loop compensation to be the given value (1 g (0.04 oz)/s). Stop calculating the throttle sensor temperature compensation. (Hold the previous value.)
