This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a part in your car's engine that helps it run smoothly. Imagine a conductor in an orchestra not giving clear signals to the musicians. The engine's 'conductor' isn't sending the right signals to make everything work together nicely.
The engine control module (ECM) has detected a low voltage signal from the camshaft position sensor for Camshaft A on Bank 2.
The camshaft position sensor monitors the position and speed of the camshaft. This information is used by the ECM to control the timing of the engine's valves. A 'low circuit' condition means that the voltage signal from the sensor is lower than expected, which can affect engine performance.
• Check Engine Light is on
• Poor engine performance
• Engine may stall or run rough
• Faulty camshaft position sensor
• Wiring issues such as a short or open circuit
• Damaged or corroded connectors
Camshaft: A shaft in the engine that controls the opening and closing of the intake and exhaust valves.
ECM: Engine Control Module, the computer that manages engine functions.
• Scan the vehicle for codes and freeze frame data
• Inspect the camshaft position sensor and its wiring
• Test the voltage and ground signals at the sensor
• Replace the camshaft position sensor if faulty
• Repair or replace damaged wiring or connectors
• Clear the codes and test drive the vehicle
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance and inspections
• Keep electrical connections clean and secure
• Address engine issues promptly
Sensor Issue
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid driving the vehicle if performance issues are severe
Check with the vehicle manufacturer for warranty coverage on engine sensors.
Camshaft position sensor issues have been common in vehicles with higher mileage or insufficient maintenance.
Moderate – Addressing this issue soon can prevent further engine performance problems.
Driving with a malfunctioning engine sensor can lead to increased emissions and potential safety hazards.
• Engine at operating temperature
• Vehicle in park or neutral
The camshaft position sensor is typically located near the top of the engine, on the cylinder head of Bank 2.
Q: Can I drive with a P23EA code?
A: It's not recommended to drive for extended periods with this code, as it can lead to engine performance issues.
Q: How long does it take to fix a P23EA code?
A: The repair time can vary, but diagnosing and fixing the issue typically takes a couple of hours.
