2001 Nissan Maxima Problems
Check Engine Llight Due to Failed Ignition Coil
The Check Engine Light may illuminate indicating a primary ignition signal fault. Many times the cause is an ignition coil(s) that has failed. The problem in the coil causes the spark energy to feedback through the wiring harness into the other coils. If this is not repaired, it can damage the other coils (blistering on the coils may be seen).
Idle Speed Control Motor May Fail and Damage ECU
The idle speed control motor may fail and possibly damage the engine's engine control unit.
Drivability Concerns Due to Corroded Ground Inside the Mass Air Flow Sensor
The ground inside mass air flow (MAF) sensor can corrode and possibly cause drivability problems. The corrosion is enough to affect the sensor data but not enough to create a trouble code. Diagnosing this can be difficult because it won't always illuminate the Check Engine Light.
Crank angle sensor may fail
The crankshaft angle sensor may stop functioning. Failure of the sensor may cause an inability to regulate the engine's timing, causing the car to drive poorly or fail to start.
Various Electrical Issues Due to Damaged Engne Wire Harness
One or more wires in the engine wiring harness may break at the harness bend near the right strut tower. Symptoms include: Check Engine Light illumination, rough idle, drivability problems, and/or an inoperative air conditioner. Any broken wires will need to be repaired.
Oxygen Sensor May Fail Due to Leaking Power Steering Pump
Oxygen sensor failures are common due to fluid leaks from the power steering pump. The power steering pump typically leaks directly onto the sensor and causes the wiring to fail. If the leaks are not repaired when the oxygen sensor is replaced, the sensor will fail again.
ECM updates for Check Engine Light issues
Software/programming updates to the Engine Control Module (ECM) are available to help solve some issues with Check Engine light illumination.
