• Stuck throttle position sensor.
• Malfunction in ECU.
• Open or short circuit in wire harness.
• Defective coolant temperature sensor.
• Malfunction in ECU.
• Open or short circuit in wire harness.
• Defective intake air temperature sensor.
• Malfunction in ECU.
• Open or short circuit in wire harness.
• Defective intake air pressure sensor 2.
• Malfunction in ECU.
• Intake air pressure sensor 2 hose is detached, clogged, kinked,
or pinched.
• Malfunction in ECU.
• Oil pressure dropped.
• Open or short circuit in wire harness.
• Open or short circuit in ignition system sub-wire harness.
• Malfunction in cylinder-#1 ignition coil.
• Malfunction in ECU.
• Malfunction in a component of ignition system.
• Open or short circuit in wire harness.
• Open or short circuit in ignition system sub-wire harness.
• Malfunction in cylinder-#2 ignition coil.
• Malfunction in ECU.
• Malfunction in a component of ignition system.
• Open or short circuit in wire harness.
• Open or short circuit in ignition system sub-wire harness.

• Malfunction in a component of ignition system.
• Open or short circuit in wire harness.
• Malfunction in throttle body.
• Malfunction in throttle cable.
• ISC valve is stuck fully open due to disconnected ISC unit hose
or coupler. (High engine idle speed is detected with the ISC
valve stuck fully open even though signals for the valve to close
are continuously being transmitted by the ECU.)
• Malfunction in ECU.
