How much does VVT solenoid replacement cost?

VVT solenoid replacement typically costs $150-$400 including parts and labor. The solenoid itself costs $50-$150, and it is usually accessible for a relatively quick replacement.

Can I fix VVT problems with an oil change?

In some cases, yes. If the VVT issue is caused by dirty oil, performing an oil change with the correct grade oil can resolve the code. However, if the solenoid or phaser is damaged, replacement is needed.

P1008

Variable Valve Timing Control System — Electrical (Honda)

Moderatevariable valve

Overview

The P1008 diagnostic trouble code indicates a variable valve timing control system — electrical (honda) condition. This code relates to the variable valve timing (VVT) system, which adjusts camshaft timing for optimal performance across the engine's RPM range. VVT issues often stem from oil quality or flow problems and can cause rough idle, poor performance, and decreased fuel economy.

Symptoms

Poor fuel economy
Check Engine Light (MIL) illuminated
Reduced engine power and acceleration
Rough idle or engine hesitation

Common Causes

Faulty VVT solenoid/actuator (oil control valve)
Worn timing chain or stretched chain
Faulty camshaft position sensor
Dirty or low engine oil

Diagnosis Steps

1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
2Check engine oil level and condition; change oil if dirty or incorrect viscosity
3Test the VVT solenoid (oil control valve) with a multimeter
4Inspect the VVT solenoid screen/filter for debris or sludge
5Monitor camshaft position sensor data using scan tool live data

Estimated Repair Cost

$150 — $1,000

Cost varies by vehicle, location, and repair shop. Includes parts and labor.

Frequently Asked Questions

Yes, dirty or low-quality engine oil is one of the leading causes of VVT system problems. Oil sludge can clog the VVT solenoid screen and oil passages, preventing proper cam timing adjustment.
