What does rocker arm oil pressure switch do?

What does rocker arm oil pressure switch do?

This code indicates that there is an issue with rocker arm oil pressure switch. The Rocker arm oil pressure switch verifies the correct oil pressure in the Variable Valve Timing (VVT) mechanism, and is often referred to as the VTEC (Variable Valve Timing & Lift Electronic Control) switch.

Where does the ECM and PCM monitor oil pressure?

The ECM/PCM monitors oil pressure in the hydraulic circuit of the VTEC mechanism using the rocker arm oil pressure switch (VTEC oil pressure switch) downstream of the rocker arm oil control solenoid (VTEC solenoid valve).

What is the code for the VTEC oil pressure switch?

According to the service manual code 2646 is for rocker arm switch (VTEC oil pressure switch) low voltage. I have the ussual problem of the Element bogging down at 4,000 rpm’s.

How much does it cost to repair a Honda rocker arm?

Please try again later. The cost of diagnosing the P2646 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

What is the oil pressure switch on a Honda p2646?

P2646 HONDA | Rocker Arm Oil Pressure Switch Circuit Low Voltage | The Variable Valve Timing and Lift Electronic Control (VTEC) system activates the Rocker Arm Oil Control Solenoid (VTEC Solenoid Valve) by command from

Why is the oil pressure on my Honda Element so low?

Low Oil – If the dipstick is not registering oil at all, it may be too low for the VTEC system to function properly. Wiring Issue – P2646 indicates that the voltage from the VTEC/Rocker oil pressure switch is low. This means that a wiring issue very well could be at fault.

What causes check engine light on Honda Element p2646?

It can get dirty and cause P2646. The VTEC system controls the variable valve timing in your Element. It does this by activating the VTEC/Rocker arm solenoid. It uses the Rocker Arm oil pressure switch to monitor the pressure of this system. When the pressure is lower than the solenoid, the check engine light will come on and you’ll get P2646.

What is the pressure switch on a Honda p2647?

P2647 HONDA | Rocker Arm Oil Pressure Switch Circuit High Voltage | The VTEC system activates the rocker arm oil control solenoid (VTEC solenoid valve) by command from the engine control module (ECM)/powertrain control

What does variable valve timing and lift ( VTEC ) do?

The Variable Valve Timing and Lift Electronic Control (VTEC) system activates the Rocker Arm Oil Control Solenoid (VTEC Solenoid Valve) by command from the Engine Control Module (ECM) / Powertrain Control Module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that switches valve timing between Low and High.

How does the VTEC system work on a Honda?

The VTEC system activates the rocker arm oil control solenoid (VTEC solenoid valve) by command from the engine control module (ECM)/powertrain control module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that switches valve timing between Low and High.
