What does a rocker arm oil pressure switch do?
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 is the VTEC oil pressure switch on a 2006 Honda CRV?
Hi Sir or Madam, welcome to Just Answer. I’m acuramstr.It is on the back side of the head on the passenger side of the engine Here is a picture. If you are getting a v-tec code first check the oil level and condition.
What happens if your Honda CRV has low oil pressure?
One of the most serious issues that can happen to your Honda CR-V ‘s engine is if ends up with low oil pressure. Low oil pressure will cause the engine to seize up. When the oil pressure light on, it should be assumed that the engine locking up is imminent. We advise not running the engine until the issue can be properly diagnosed.
What is the rocker arm actuator on a Honda?
The electronic control module regulates various actuators on the internal combustion engine and one of the actuators that ECM regulates is the rocker arm actuator. A rocket arm actuator system is a switch that controls the flow and pressure of oil in the engine and it also consists of oil passages. What causes the P2646 trouble code?
How does the rocker arm oil pressure switch work?
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.
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 is the oil pressure switch on a Honda CRV?
The VTEC system controls the variable valve timing in your CR-V. 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.
Why is there no oil in my Honda CRV?
There is a tube in your CR-V that takes the oil from the pan to the oil pump. This is called the pickup tube. This tube can fall out, which will cause no oil to get to the oil pump. Modern engines use a bypass valves to keep oil flowing to the engine even when the filter is clogged.
What does the rocker arm oil pressure switch do?
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.
What does low oil pressure mean on Honda?
With correct engine oil level, a “Check Engine Oil Level” message may appear on the MID or the navigation screen. The “Low Oil Pressure” indicator on the instrument panel may also be on. After verifying the wiring and connectors are in good condition, replace the oil pressure switch.
