This allows for a more efficient cam profile at any speed. The image below shows a typical oil flow control valve, with the solenoid and electrical connector making up the top part of the assembly. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. You can even use a can of the stuff you use for cleaning computer keyboards to clear the area. In case the Check Engine Light stays off then you may have an intermittent problem. This is referred to as internal exhaust gas re-circulation, allowing very fine dosage of the amount of exhaust gas recycled.
This code could also be set as the result of a performance failure in the system. Is the resistance below 3. There is a factory service bulletin for the following Nissan models: 2003 Nissan Altima 2004 Nissan Altima 2005 Nissan Altima 2004 Nissan Quest 2004 Nissan Maxima When is the P0340 code Detected? The replacement part has an O-ring on it. Crankshaft Position Sensor A Circuit Intermittent P0340. A variation in the timing between the crankshaft and the Bank 1 camshaft will trigger the check engine light. The code could also be set as the result of a performance failure in the system.
First we'll get into the importance of the code number as it relates to failure on the intake or exhaust side. The engine timing could be out of sync. The wiring harness to the intake camshaft position sensor may also develop a poor connection. At the end of the article review the simple repair procedure with a few important tech tips thrown in. Replace the solenoid if a direct power supply fails to activate the solenoid.
Design specifics vary from system to system but in principle, the pressurized oil acts on an actuator to rotate the camshaft either clock-wise, or counter-clockwise relative to a base timing position to advance or retard the valve timing, depending on operating conditions such as varying loads on the engine, and throttle inputs from the driver. Wear and deterioration may be observed in the timing belt, which would require a replacement. Due to emissions and performance standards, manufacturers have installed systems to increase the engine valve lift under certain conditions based upon load and performance. Without performing a proper diagnostic procedure, a vehicle owner could spend several hundreds of dollars only to still have the same fault code. The difference between the to is considered to be the amount of ''error''. The function of variable valve timing is to enable engines to develop more torque under different operating conditions.
Clean, replace, or repair connector as required. I have seen vehicles that have come in from other repair shops after having spent hundreds of dollars to only fix their issue in less than an hour. You can also set a code P0014 for the actuator valve over advancing the camshaft timing. At moderate engine speeds, the intake valves open much earlier, which boosts torque and permits exhaust gas re-circulation inside the combustion chambers, reducing fuel consumption and exhaust emissions. When it's referring to a bank number, it's talking about which set of cylinders. If you set a check engine light code P0013 this stands for camshaft position actuator solenoid valve B. It is considered generic because it applies to all makes and models of vehicles 1996-newer , although specific repair steps may be slightly different depending on the model.
It works with your existing smartphone or tablet to let you easily graph, scan, check emission monitors, produce diagnostic reports, clear codes, and much more Subscribe Our Channel. . Since the manufacturer uses two separate valves identifying and replacing the correct one becomes important. Cylinder 7 Misfire Detected P0308. Cylinder 4 Misfire Detected P0305.
First you have to pull up on the lock tab so that you can push on the release button and then wiggle the connector free from the actuator. These are essential to prevent solid particulate matter in the oil from interfering with the operation of the actuator on the camshaft. This area collects a lot of dirt and more importantly sand particles. The original assigned General Motors part number for the exhaust side solenoid actuator valve is 12655421. If you would like to add anything, please leave a comment below. Give close inspection to the Bank 1 variable valve timing and the variable camshaft timing.
Causes of Trouble Code P0010 A lot of issues can cause the computer to give a trouble code of P0010. The target error diagnostic : evalutes the actual camshaft position versus the modeled position when the camshaft is in a relatively stable position. Possible Uplander P0010 Causes There are quite a few different things that can cause the P0010. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. With that said, if you follow my advice above and below you'll go ahead and replace both at the same time, so that the actual position of the parts isn't important. Perform the Powertrain verification test.
