![]() ![]() If it does, come on back and let us know and we'll figure out what your next step should be. Clear the code and drive the car for a while and see if it comes back. So yeah, start by changing the oil and filter. If you swap them around and the error never moves no matter how you mix up the solenoids, then it may be something else such as a failed camshaft actuator, damaged timing components, a wiring problem, or an issue with the PCM or camshaft position sensor. Swap positions of them two at a time and recheck when you find the faulty one, the error will give a different error number i.e., it'll change to error P0011. If you're still getting the error after that, you will need to determine which one is at fault. An inline 4 cylinder will most likely only have two, while a V6 will again have four.Īnyway, if the oil change doesn't do the job, then the next thing to try would be removing and cleaning them with solvent. In general, there'll be two solenoids for each cylinder head my Subaru has two heads, thus four solenoids. I can't say for sure on your car, but at least on the Subarus there are four of those solenoids, one for each intake and exhaust camshaft on both sides of the engine. I had that same error come up on my wife's Subaru Crosstrek, and as it turned out, simply changing the oil fixed the problem. These are powered by oil pressure, so low or dirty oil can easily affect their operation. In this article, we will show you how to fix exhaust camshaft position timing on a Toyota Camry.The variable valve timing on modern engines is controlled by something called an oil control solenoid. If your car’s exhaust camshaft position timing is off, the result can be rough engine performance and poor fuel economy. Replace any faulty sensors and connectors. Reconnect all cables and check for proper connection at ECU connector pins 10-12 on engine block (or near where they connect on later model cars).ĥ. If any are dirty or damaged, replace them as needed.Ĥ. Clean and inspect all sensors related to timing and combustion (camshaft position, crankshaft Position Sensor, camshaft Advance Sensor, etc.). Check the cable connecting the sensor to the engine control unit (ECU). Remove the exhaust manifold and spark plugs.Ģ. Here’s how to fix exhaust camshaft position timing:ġ. If the sensor isn’t working correctly, this can cause timing problems. The sensor measures the time it takes for the engine to reach full power after the intake valves open. If your car has an exhaust camshaft position sensor, it can help diagnose and fix timing issues. How to Fix Exhaust Camshaft Position Timing If you see evidence of a leak or if there is anything blocking oil from reaching the camshafts, replace the ECD valve immediately. Next, use a flashlight to look inside the chamber where the camshafts rotate. Once you have located the valve, use a wrench to unscrew it from its mounting bracket. Carefully lift up on these bolts until you can see the ECD valve itself. To do this, remove the valve cover and locate the three bolts that hold it in place. If you are unable to find any evidence of a leak, your next step will be to inspect the ECD valve itself. If there is no visible damage, remove the spark plugs and inspect the cylinders for signs of oil leakage. ![]() The camshaft position sensor detects camshaft rotation, and forwards the information to your car’s Powertrain Control Module (PCM). To diagnose an ECP oil leak, first check for any obvious signs of damage to the engine. The P0016 OBD-II generic code is triggered to alert you that the camshaft position sensor (CMP sensor) for Bank 1 isn’t correlating with the crankshaft position sensor (CKP sensor). A leak in this system can cause severe damage to the engine and may even result in a complete loss of power. The ECP valve regulates the flow of oil to and from the engine’s camshafts. If you experience one or more of the following symptoms, it is likely that your exhaust camshaft position (ECD) valve has failed: harsh engine acceleration, poor fuel economy, rough idle, and poor emissions. In some cases, the ECP can cause misfires and poor fuel economy. If the ECP is not functioning properly, the engine may not idle correctly, or may run rough. The ECP can be damaged by things like worn or misshapen lobes, lack of lubrication, or old oil. It uses sensors to measure engine speed and camshaft position, and adjusts the timing accordingly. What is Exhaust Camshaft Position (ECP)?Įxhaust camshaft position (ECP) is a system on newer engines that controls timing of the exhaust valve opening. By following our instructions, you can restore your car’s engine performance to its former glory in no time at all. In this blog post, we will show you how to fix exhaust camshaft position timing using a few simple tools and some basic knowledge. This is because the timing belt can become stretched or broken over time, leading to incorrect camshaft positions and poor fuel economy. If you own a car with an exhaust camshaft, you’ve probably been dealing with problems with its timing for some time now. ![]()
