How does the camshaft position actuator work?
The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The CMP actuator solenoid is controlled by the control module.
How does the camshaft position sensor work on Kia Rio?
This procedure will determine if the Camshaft Position Sensor is able to send signal to the ECU. This is done by measuring the voltage across the signal and ground wires of the sensor. Follow these steps in sequence: Make sure the ignition switch is off. Locate the Signal and Ground wires. In Kia Rio, these wires are as shown in Fig. 5.
What to do if camshaft position sensor malfunctions?
Check if the Camshaft-Position-Sensor connector is fully inserted into the sensor. Check the wiring harness for possible damage (broken or shorted wires). The wiring harness should be routed away from the high-tension cable to prevent interference.
When does the camshaft position sensor rise back to 12 volts?
It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).
What’s the trouble code for a camshaft actuator?
This article originally appeared on YourMechanic.com as P0010 OBD-II Trouble Code: “A” Camshaft Position Actuator Circuit (Bank 1). Autoblog is partnering with YourMechanic to bring many of the repair and maintenance services you need right to you.
What does the camshaft actuator do on a Kia Optima?
They operate hydraulically, and need to use the oil to move up and down. An oil change and a little drive time is often enough to clear P0014. Bad Camshaft Actuator – The camshaft actuator is a solenoid that engages the camshaft and actually controls its timing. They typically aren’t that expensive.
What happens when the camshaft position sensor fails?
Once your car’s computer detects a CMP sensor failure, it will trigger the engine light and store a diagnostic trouble code (DTC) in its memory (see the table below for common camshaft position sensor trouble diagnostic codes). As you may expect, the specific location of the camshaft position sensor varies by a vehicle’s make and model.
What causes an exhaust camshaft position actuator code p0013?
Here are the most common causes of an exhaust camshaft position actuator solenoid valve control circuit problem or code P0013: 1 Bad VVT solenoid (aka oil control valve) 2 Problems with the VVT solenoid control circuit 3 Issues with the PCM, such as a pending software update
