1. MAF and IAT sensor 3. Main relay 5. To other sensors
2. Ignition switch 4. ECM
DTC detecting condition Trouble area
• MAF volume is greater than 20 g/sec even if engine
revolution is less than 900 rpm and intake manifold
pressure is less than 40 kPa (5.80 psi) with TP less than
1.5°.
• MAF volume is lower than 10 g/sec even if engine
revolution is more than 2500 rpm and intake manifold
pressure is more than 60 kPa (8.70 psi) with TP more than
12°.
(2 driving cycle detection logic)
• Air intake system (clog or leakage)
• MAF sensor circuit
•MAF sensor
• TP sensor and/or its circuit
• MAP sensor and/or its circuit
•ECM
