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).

Check Engine Light Due to Failed EVAP Canister Vent Valve
The Check Engine Light may illuminate due to a defective charcoal canister vent control valve. The charcoal canister is a component in the Evaporative emissions (EVAP) system. Our technicians tell us a failed vent valve will require replacement.
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.
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.
Trunk Lock Assembly May Fail Causing Various Issues
The rear spoiler (if equipped) may allow water to leak into the trunk and onto the trunk lock assembly. This could cause corrosion on the lock assembly leading to false "trunk open" signals to the body control module (BCM) and erroneous security alarm system activation.
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.
Leaking power steering pump can cause noise/steering problems
If the power steering pump develops leaks, it can drip onto the lower control arm bushing causing the bushing to deteriorate. A knocking noise will be heard when driving over bumps and it may become more difficult to control the vehicle.
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.
