Some vehicles will not start without a viable timing signal from an engine’s camshaft position sensor. This occurs when one or more timing-related diagnostic trouble codes are logged by a vehicle’s PCM. In most cases, a faulty camshaft position sensor will cause a vehicle’s check engine light to illuminate. The following are several of the most prominent issues associated with a faulty or failing Camshaft Position Sensor. Learning to recognize these symptoms can be invaluable when attempting to diagnose an issue of this type. Bad Camshaft Position Sensor SymptomsĪ faulty Camshaft Position Sensor can produce a number of secondary symptoms, some of which tend to be relatively troubling in nature.

If in doubt as to the exact position of your vehicle’s camshaft position sensor, secure and consult a copy of the factory-specific service and repair manual for your particular vehicle. Alternatively, on other vehicles, this sensor is bolted to an engine’s valve cover or cylinder head. The sensor in some engines is bolted directly to a port within the unit’s front timing cover. The exact position of an engine’s camshaft position sensor differs from one vehicle to the next. The camshaft position sensor itself operates on the principle of magnetism, picking up its signal from a tone ring positioned at one end of the camshaft position sensor.Īs a camshaft spins, and the teeth of this tone-ring pass in front of the camshaft position sensor itself, a waveform signal is created, thereby providing feedback to an engine’s management software. Without such feedback, it would be nearly impossible to accurately regulate injector pulse timing or spark advance.Īdditionally, the implementation of such technology as variable valve timing between bank 1 and bank 2 of a particular engine would be little more than a pipe dream. The timing of an engine’s ignition system and fuel injectors tends to be highly reliant upon camshaft timing as a whole. What Is a Camshaft Position Sensor? Camshaft position sensorsĪ camshaft position sensor (CMP) is a specialty device that records and relays information to a vehicle’s ECM/PCM, regarding the actual position of an engine’s camshaft when in rotation.Ĭonsequently, this information proves vital in determining the overall position of each intake and exhaust valve found in both engine banks, due to the fact that cam/valve timing correlates through the use of lifters/pushrods.

Read on to learn more about the various symptoms associated with a faulty camshaft position sensor, as well as how to handle such a situation, should it arise in the future.
Recognizing these symptoms often proves key when attempting to quickly remedy the issue at hand. When this occurs, a host of secondary symptoms often arise, some of which tend to be relatively severe in nature. Unfortunately, like any electrical device, an engine’s camshaft position sensor is prone to occasional malfunction and failure. This feedback is often compared to that provided by a vehicle’s Crankshaft Position Sensor. This particular sensor provides accurate feedback regarding the precise position of an engine’s rotating assemblies. One such sensor is the Camshaft Position Sensor. Of all sensors found on today’s engines, few are as important as those which relate to engine timing. Most notably, modern internal combustion engines come equipped with a host of specialty control modules, sensors, and intelligent devices, allowing them to adjust key operating criteria on the fly. Use a paint stick to create an alignment mark (16) on one of the timing chain links and the adjacent tooth on the exhaust camshaft position actuator (15).Today’s internal combustion engines are far more equipped to sustain consistent operation than engines of yesteryear. The camshafts will be parallel with the camshaft cover rail (1).Įnsure that the camshaft timing chain and the camshaft position actuators are marked for proper assembly. Rotate the crankshaft using the crankshaft balancer fastener until the camshafts are in a neutral (low tension) position. Rotate the crankshaft balancer fastener in a clockwise direction ONLY. Refer to Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Intake and Camshaft Position Actuator Solenoid Valve Solenoid Replacement - Bank 1 (Right Side) Exhaust. Remove the right intake and exhaust camshaft position actuator solenoids. Refer to Camshaft Position Sensor Replacement - Bank 1 (Right Side) Intake and Camshaft Position Sensor Replacement - Bank 1 (Right Side) Exhaust. Remove the right intake and exhaust camshaft position sensors.
