Possible Causes
NOTE:
- Monitor description. Mass air flow sensors left/right flow to low
- This DTC is set when the powertrain control module has measured a signal voltage below a specified range but not necessarily a short circuit to ground, gain too low.
- Blocked air filter
- Other related Diagnostic Trouble Code(s)
- Air induction system incorrectly installed components, loose hose clips or air leakage
- Mass air flow sensor contamination by oil or debris
- Electric throttle blade contamination by oil or debris
- Mass air flow sensor circuit, short circuit to ground, short circuit to power, open circuit, high resistance
- Throttle adaption failure
