How do I fix error code P2647?
What repairs can fix the P2647 code?
- Adding or changing the engine oil.
- Replacing the timing belt or chain as well as other timing components.
- Replacing the oil control valve or other variable valve timing components.
- Repairing or replacing wiring or connectors that are associated with the variable valve timing system.
Can I drive with code P2647?
You can still drive the vehicle till you get this fixed, the reason for the CK ENG LT is to protect the catalytic convertor and the catalytic convertor protects the environment from harmful emission from the engine, you drive this too long you degrade the catalytic convertor.
What is a rocker arm actuator system stuck on bank 1?
The ECM detects a problem in the rocker arm system for bank 1. The oil passages are clogged or the oil pressure is not up to specifications. The rocker arm actuator is clogged with sludge or is sticking intermittently. Too thick of an oil will cause the system to not work as designed.
What is a rocker arm actuator Honda?
The rocker arm actuator is an oil pressure switch which controls the flow of oil to critical upper engine cylinder head components. The actuator will measure how much oil is flowing through it and report it to the ECM. The ECM will administer changes where it sees fit.
Can you drive with a bad VVT solenoid?
Can You Drive with a Bad VVT Solenoid? Even though you may technically be able to continue driving with a bad VVT solenoid, the issue can cause damage to additional parts, such as the VVT actuator. So, you should address the issue as soon as possible.
What are the symptoms of a bad VTEC solenoid?
Here are a few symptoms of a worn out or broken VVT solenoid.
- Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
- Engine oil is dirty.
- Rough engine idle.
- Decrease in fuel economy.
What does the VTEC pressure switch do?
VTEC stands for Variable Valve Timing with Electronic Control. 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.
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.
Where is the rocker arm located?
Rocker arms are typically located between the pushrod and intake and exhaust valves. They are pushed and pulled by pushrods to “rock” up and down, opening and closing the exhaust valve and intake valve of the combustion chamber on engines with a camshaft below the engine.
How long can you drive with a bad rocker arm?
If your lifters are bad or collapsed, you shouldn’ t drive more than 100 miles and you should use those miles to drive your vehicle to the repair shop.
What causes a rocker arm to come off?
A The rocker arms that actuate the valves in this engine pivot on a special bolt that is threaded into the cylinder head. The most likely cause for the loose rocker arm bolts in your engine is either inadequate tightening originally, or an effort to adjust the rocker arms at some point in the engine’s life.
What is a rocker arm actuator system performance?
In vehicles equipped with VTEC, the rocker arm control solenoid supplies hydraulic pressure to the variable timing and lift mechanism. This allows the VTEC system to adjust valve timing and lift as needed. The VTEC system controls the rocker arm control solenoid through the powertrain control module (PCM).
Can a bad rocker arm cause a misfire?
A bad coil, worn plug, or plugged injector are some of the more common causes of a misfire. The rocker arm is falling out of place in many 3.7 and 4.7 engines and this is very disturbing. A rocker arm out of place is a very severe misfire.
How much does it cost to replace a VTEC solenoid?
The average cost for a Variable Valve Timing Control Solenoid Replacement is between $198 and $253 but can vary from car to car.
How do you unstick a rocker arm?
The lifter that is stuck should tick under the rocker arm. Loosen the rocker arm bolt and remove the lifter. Fill a small cup with penetrating oil and soak the lifter in it, preferably overnight. Reinstall the lifter and torque the rocker arm to the correct specification.
