How much does it cost to fix a rocker arm actuator?

Because rocker arm repair is tedious work, it can be time intensive so hiring an auto mechanic or dealership to do the job is not cheap. Expect to pay anywhere from $500 to $1,500 (parts + labor) depending on the vehicle. A good chunk of the expense is for labor as it can take a long time to access the necessary parts.

What is a rocker arm oil pressure switch?

The Rocker arm oil pressure switch is used to verify the oil pressure in the Variable Valve Timing mechanism.

How do I bypass a VTEC pressure switch?

This can be easily bypassed with a simple wiring trick: On your engine harness, locate the VTEC oil pressure switch plug/wire (this wire comes from OBD1 ECU pin D6). Use a common T-tap or other method and simply tap this into the VTEC solenoid valve wire (the VTEC solenoid wire comes from OBD1 ECU pin A4).

How much is a rocker arm actuator?

What causes rocker arm failure?

One of the major causes of component failure is faulty manufacturing. This includes all effects that increase brittleness or those inducing cracks and or stress raisers in the component. Improper heat treatment has been considered as major causes of many failures in the literature.

How do you check if the VTEC is working?

The meter should read very very low voltage until vtec hits. If vtec activates then the voltage should read around 12. if not then your ecu may not be functioning properly.

Is it worth replacing rocker arms?
