![]() It may become erratic, stall regularly, or may struggle to start on occasion. Most people will notice some issues with the engine prior to the P0011 code being generated. It’s a generic error code produced by an over-advanced condition which typically occurs during the retarding or advancing of the camshaft timing. Check each of the terminals and clamps for corrosion or damage as well.Error code P0011 indicated that the ECM has detected that the bank 1 intake camshaft is more advanced than it was instructed to be. In addition, check that all of the cables are clean, tight and in good condition (inspect them visually) and make sure they’re not touching any bare metal surfaces they shouldn’t be touching. A full charge should be 12 volts or more at rest it may drop down to around 10 volts when cranking and then bounce back up to 12 volts or so once it starts running. Remove the positive battery cable next.Īt this time, use a multimeter to test the battery (volts and cold cranking amps).Disconnect the negative battery cable first this prevents sparks from lighting up any hydrogen gas that may have accumulated around the battery.This is important for your safety as well as protecting sensitive electronic components that could become damaged should you accidentally short them out during your diagnosis. This is important for your safety as well as protecting sensitive electronic components that could become damaged should you accidentally short them out during your diagnosis īefore you start your diagnosis, with the ignition off, disconnect the vehicle’s battery. With the ignition off, disconnect the vehicle’s battery. Timing Chain/Belt Tensioners or Hydraulic Lifters.Engine Oil Viscosity (contaminated with fuel or glycol).Camshaft Sprocket (worn or damaged teeth).Timing Adjustment Mechanism (weak or damaged tensioner, stretch timing chain/belt).Timing Chain/Belt (stretch or broken tensioner).To help you pinpoint the exact problem, I’ve included a list of all the parts that could be responsible for this code and what they do below: The most common cause of this code is a failed actuator solenoid, but there are many other possible causes. ![]() The first thing you need to know to diagnose the camshaft positioning sensor code P0012 is that it can be caused by numerous things. Roller cams eliminate this issue because they do not contact anything other than its own bearings: instead, they ride on needle bearings inside their housing which allows them to turn faster without resistance from friction caused by contacting material(s). Flat-tappet cams use lobes that contact directly against lifters This creates friction that slows down camshamp speed at high rpm range due to friction between contact surfaces (it would be like running with sandpaper under your shoes). ![]() There are two types of cam profiles: flat-tappet cams and roller cams. The amount of air in a cylinder is referred to as its “volume” or “displacement” (the volume being measured in liters). A gasoline engine with spark plugs needs more air to burn more fuel, but there is only so much air that a given cylinder can contain at one time. In a gas-powered engine, the timing of when these valves open and close has an impact on how much fuel enters into the cylinder, which in turn affects power output. They control the opening and closing dates of the intake valve and exhaust valve. The camshaft (s) is/are an essential part of the engine.
