Symptoms of a Faulty VVEL Actuator
Identify the warning signs of a faulty VVEL actuator motor on Bank 1 by recognizing its distinct symptoms.
You may notice reduced engine power, poor fuel efficiency, and a rough idle or stalling. Engine misfires are also common, which can lead to decreased valve performance.
If you’re experiencing any of these issues, it’s likely that your VVEL actuator motor is malfunctioning. Keep in mind that a faulty VVEL actuator can cause improper valve operation, affecting engine performance and potentially leading to engine stalling.
Be sure to address these symptoms promptly to prevent further damage to your engine.
Diagnostic and Repair Procedures
Most P1090 code diagnoses require a thorough investigation to pinpoint the root cause of the issue. You’ll need to follow a systematic approach to diagnose and repair the problem. Start by performing a scan procedure to confirm the P1090 code and identify the exact issue. Then, inspect the wiring harness and connections for damage or corrosion and repair or replace as needed.
| Diagnostic Step | Procedure | Purpose |
|---|---|---|
| Scan procedure | Connect scan tool to OBD-II port | Identify trouble code and freeze frame data |
| Actuator testing | Test VVEL actuator motor for proper function | Determine if actuator motor is faulty |
| Wiring inspection | Inspect wiring harness and connections | Identify damage or corrosion |
Replacing the VVEL Actuator Motor
When replacing the VVEL actuator motor, you’ll need to access the Bank 1 engine compartment, where the motor is typically located.
You’ll need to disconnect the electrical connector and remove the mounting bolts to remove the faulty motor. Inspect the motor’s electrical connector and wiring harness for signs of damage or corrosion, and repair or replace them as needed.
If you’ve confirmed motor failure, you can proceed with actuator replacement. Verify the new motor is properly seated and secured, and reconnect the electrical connector.
Reconnect the battery and clear the P1090 code to test the VVEL system. If the issue persists, you may need to perform additional troubleshooting or repairs.
Cost and Repair Time Estimates
Requiring a thorough assessment, the cost to fix the P1090 code can vary greatly depending on the underlying issue and the type of repair facility you choose.
On average, replacing the VVEL actuator motor can cost between $200 and $600. However, diagnostic time, labor rates, and part prices can differ based on location and type of repair facility.
Labor costs can range from $75 to $150 per hour, depending on the shop’s rates. To get a more accurate repair estimate, it’s best to get quotes from different shops. Be sure to ask about any additional costs or fees associated with the repair.
