What is a VVT pressure switch?
The variable valve timing (VVT) oil pressure switch is a switch located near and ported to the VVT solenoid, notifying on-board computers of proper oil delivery to the VVT system. The VVT system utilizes re-routed engine oil pressure to the rocker arm pistons above to increase the engine's efficiency and power. via
How much does it cost to replace VVT pressure switch?
Labor costs are estimated between $131 and $165 while parts are priced between $168 and $192. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed. via
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). via
How do I know if my VVT is bad?
Common signs include a rough engine idle, the Check Engine Light coming on, and the engine stumbling when climbing hills or under load. via
What does VTEC pressure switch do?
The variable valve timing oil pressure switch is a normally open switch located at the VVT solenoid. When the VTEC oil pressure switch closes, the voltage should drop to zero. This is how the PCM knows if oil pressure was applied to the VTEC system. When this system fails to operate properly the ECM may set a code. via
What does the VTEC solenoid valve do?
The role of the VTEC solenoid is to control the flow of oil to the internal galleries of the overhead camshaft. Honda's VTEC solenoid works alongside the oil pressure switch, together activating the camshaft's high-performance setting. via
