This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve. The ECM receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle.

When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Search for: Search.

Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code. When there is a gap between angle of target and phase-control angle degree, the valve will stop working and the ECM will trigger the P Buick code.

The camshaft and crankshaft sensors have indicated the camshaft is more advanced than the ECM has commanded it to advance. The camshaft is too advanced when the ECM has commanded the camshaft to retard to a lower timing level. The oil is too thick causing the passages to become clogged due to lack of oil flow to and from the camshaft phasers. The ECM will turn on the Check Engine Light and command the camshaft to go to its normal starting position if possible. The engine may have a hard start condition if the cam is stuck in a too far advanced or retarded timing position.

The engine will have a reduction in fuel mileage due to the camshafts not being in their optimal positions to get the best fuel mileage. Note : The symptoms may change depending on the camshaft timing positions when the camshaft stopped advancing or retarding. A visual inspection to determine any electrical connector, wiring, or valve issues of the camshaft oil control valve for the bank 1 intake camshaft.

The technician will scan and document the codes received and view the freeze frame data to see when the code was set. The codes should then be reset to clear the OBD-II fault codes and retest the vehicle to see if the P code comes back.

If the code returns, then the next step for the technician to do is perform a manufacturer's specific pinpoint test for the P code and repair as needed. Note : Follow the manufacturer's recommended pinpoint test to narrow down the problem since each engine may be tested differently and possible engine internal damage may be done if tests are not performed in accordance with a correct procedure.

Always do a visual inspection for common problems like checking to see if all electrical connectors are connected. Check, document and clear failure codes. Test to verify the code coming back before any further tests are done. The manufacturer pinpoint test procedures should be followed step-by-step without skipping any steps to prevent a misdiagnosis and replacing of good components. The engine may have excessive fuel consumption, carbon fouling of engine components, and various drive complaints depending on the camshaft failed position.

Driving the vehicle for prolonged time with the camshafts not advancing or retarding may cause other problems to the valve train or engine depending on the cause of the failure. The engine oil passages through the camshafts and oil control valves are a specific size and only the manufacturer's recommended oil viscosity should be used.

The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.

But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. So you should chech it on our car models. Disconnected, dirty or fouled spark plugs are common causes for engines that won't start.

Spark plugs typically need to be replaced every season or 25 hours of use. You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Parts or components should not be replaced with reference to only a P DTC.

The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

P code.P is a very common trouble code. It affects vehicles with variable valve timing VVT. This means that it has the same definition for the Buick Lucerne as it does on any other vehicle.

VVT changes the frequency and distribution of gases entering and exiting the combustion chamber. This is great for both power and fuel economy. If your Lucerne has the P trouble code it will typically not pass the State emissions tests.

The Buick Lucerne utilizes camshaft actuators to change the valve lift depending on the RPM of the motor. This allows for a more efficient cam profile at any speed.

When the timing is too far advanced. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P With P, the camshaft actuator is leaving the timing too far advanced, or there is a system performance issue not working right.

When the timing is too far advanced, it can really cause some issues with the motor.

Buick Lucerne P Symptoms When the timing is too far advanced, it can really cause some issues with the motor. Decreased Gas Mileage — Now the engine can no longer adjust its cam timing on the fly, it will no longer be able to produce optimal combustion which equals poor economy. Lost Power — The engine will not be able to produce as much power. This is because the cam profile will not allow it run a performance power curve when you need more power. Tough to Start Motor — With the timing too far advanced, it is going to be difficult to start the motor, especially when it is warm.

The wiring harness to the intake camshaft position sensor may also develop a poor connection.We recommend Torque Pro. In most cases if P comes up it is due to lack of oil lubrication. You need to purchase high end oils in order to have a longer lasting camshaft oil timing system.

You definitely get what you pay for in this case. PPPPP Type B codes- will erase itself without a scanner. Type A code there is something else. If the initial P sets and other codes are present then erase all codes and do five camshaft drive cycles and then re-investigate which codes come back.

If any of these codes are present disregard and erase. If they come back it is electrical wiring or connection failure. If the valve does not respond to the criteria of the computer, it will recognize the algorithm. So, usually when the P code shows it is failure due to lack of maintenance. Most P codes are almost always a result of bad oil changes and lack of car maintenance in regards to engine lubrication.

The magnet is located by dowel pins and retained by a bolt that must be torqued correctly 30 inch-pounds. Over torqueing can break the magnet, which will cause a no start condition.

Not mounting the magnet correctly can also break it, so check to see if the magnet is still in one piece. Did you replace the magnet when you replaced the sensor? If you have a manual, locate the signal wire, and check the signal voltage with a multimeter while you crank the engine. No signal voltage find the signal voltage in the manual means no signal voltage is being generated,and with type of setup, the problem is more likely to involve the target magnet than the rest of the sensor.

I am have a Yukon hybrid with the 6.The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft s is are adjusted by the ECM through the use of an oil control valve s OCV also called variable valve timing control solenoid valves.

When trouble code P is set, it means that the intake camshaft in Bank 1 is more advanced than the ECM has told it to be. This trouble code severely impacts the drivability of your vehicle.

Continuing to drive the vehicle in this condition can cause severe damage to multiple internal engine components. Replacing sensors or components without any indication of a problem with the sensors or components. For error code P, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.
