7 Symptoms of a Bad Camshaft Position Sensor (and Replacement Cost)

Mar 30,  · Basically, camshaft and crankshaft position sensors work together to show the computer when the conditions are right for intake, compression, combustion and exhaust. Sensory Deprivation. A camshaft sensor problem will usually trigger the check engine light. From there, you can do a diagnostic scan to suss out a camshaft issue, but it won’t tell you whether the problem is the . Sep 25,  · In short, the function of the camshaft position sensor is to: Monitors the rotational rate of the camshaft; Tells the engine which valves are open and closed; Determines the timing of ignition; It’s All a Matter of Timing. So, what exactly does your car’s engine do with all the information it is sent from the position sensors on the crank and cam?

The camshaft position sensor monitors the rotation of the camshaft, specifically targeting when valves open and close. Ir camshaft sensors are mounted just above a notched ring on the camshaft. Most of these camshaft sensors will use a magnet to produce or vary an AC electronic signal that is used in conjunction with a crankshaft position sensor to determine when a position approaches top dead center TDC on posifion compression stroke.

This information will help to fine snesor spark timing and injector pulse. A car that does not run. The engine will crank but not turn over, or it will start then immediately stall. Many times when the on board computer receives an erratic signal, internal logic will understand this as a mechanical problem, and it will shut down the engine to prevent any damage. Ironically, the very same sensor may send out no signal, or be unplugged, and the posution will run, albeit poorly.

Heat, age and especially rust are the biggest culprits for sensor failure. The failure of camshaft position sensor what does it do camshaft position sensor could leave you stranded on the side of the road waiting for the tow truck.

The engine still may run poorly, Either way find a good mechanic, one who specializes in engine performance, and set an appointment — the sooner the better. In most instances, this repair should take no longer than one day. In most case, this is not a expensive repair.

Sometimes other parts what fruit can guinea pigs eat the engine need to be removed in order to access the sensor, and this may include the valve cover.

Mar 17,  · What does the camshaft position sensor do? The camshaft position sensor monitors the rotation of the camshaft, specifically targeting when valves open and close. Most camshaft sensors are mounted just above a notched ring on the camshaft. Apr 09,  · The purpose of a camshaft position sensor is to determine the position of the camshaft as it relates to the crankshaft. This data is then sent to the powertrain control module (PCM) for use with fuel injector and/or ignition system control. Common Symptoms of a Faulty Camshaft Position Sensor #1 – Check Engine Light Illuminates. The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things. On this page, you can find out how a fault on the camshaft sensor can manifest itself, and which steps should be taken during troubleshooting.

Here you will find useful basic information and important tips relating to the camshaft sensor in vehicles. The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.

On this page, you can find out how a fault on the camshaft sensor can manifest itself, and which steps should be taken during troubleshooting. Important safety information The following technical information and practical tips have been compiled by HELLA in order to provide professional support to vehicle workshops in their day-to-day work.

The information provided on this website is intended for use by suitably qualified personnel only. The task of the camshaft sensor is to work with the crankshaft sensor to define the exact position of the crankshaft drive.

Through the combination of both sensor signals, the engine control unit knows when the first cylinder is in the top dead point. The camshaft sensor works according to the Hall principle. It scans a ring gear on the camshaft.

The rotation of the ring gear changes the Hall voltage of the Hall IC in the sensor head. This change in voltage is transmitted to the control unit and evaluated there in order to establish the required data.

Check the connection line from the control unit to the sensor using the ohmmeter. Remove the connector from the control unit and remove the sensor, check the individual cables for continuity. A circuit diagram is required for the pin assignment. Reference value: approx.

Check the connection lines for short circuit to frame. Measurement between sensor plug and vehicle ground, control unit plug removed. Check the supply voltage from the control unit to the sensor.

Insert the control unit plug, switch the ignition on. Check the signal voltage. Connect the measuring cable from the oscilloscope and start the engine. A square wave signal must be displayed on the oscilloscope. UK Newsletter Video Hella team.

Functional principle. Cause of failure. This information is needed for three purposes: For the start of injection during sequential injection. For the actuation signal of the solenoid valve for the pump-nozzle injection system. For cylinder-selective knocking control. Camshaft sensor. A faulty camshaft sensor can cause the following symptoms: Starting difficulties Engine indicator lamp comes on Fault code is stored Control unit enters an emergency program.

Reasons for failure of the camshaft sensor can be: Mechanical damage Break in the encoder wheel Internal short circuits Interruption in connection to the control unit.

Hall generator — example OK. Checking the connection line. Checking the connection lines for short circuit to frame. Checking the supply voltage. Checking the signal voltage. Make sure that the distance to the encoder wheel is correct and that the seal fit is correct.
