What is OBD-II Code P2619 – Crankshaft Position Signal Output Circuit High

Crankshaft position sensor-related OBD-II codes have different definitions and diagnostic paths depending on the vehicle make and model. One of these codes is P2619, which indicates a high output signal from the crankshaft position sensor circuit. A mechanic can diagnose and repair P2619 by following a standard diagnostic procedure that involves testing the sensor, circuit, and related components. In this article, we will explain what P2619 means, what can cause it, and how to repair it.

What is P2619?

P2619 is an OBD-II code that indicates a high output signal from the crankshaft position sensor output circuit. This code is specific to vehicles that use a digital signal (square wave) from the crankshaft position sensor to compute engine timing and other performance parameters. P2619 can be triggered by a range of conditions that affect the sensor or the circuit, including sensor failure, wiring issues, and sensor misalignment.

What causes P2619?

P2619 can be caused by several factors, including:

1) Sensor issues – The crankshaft position sensor may fail due to wear and tear, dirt accumulation, water exposure, or other factors. When this happens, the sensor may not produce the correct signal, leading to P2619.
2) Circuit issues – If the wires, connectors, or other components of the crankshaft position sensor circuit are damaged or corroded, the signal output may be high, resulting in P2619.
3) Misalignment – The crankshaft position sensor may not be aligned with the crankshaft correctly, leading to an incorrect signal or no signal at all. In this case, the engine may not start or may run poorly.

How to diagnose P2619?

Diagnosing P2619 involves several steps, including:

1) Check the code – Use an OBD-II scanner to read the code and determine whether it is still present after clearing it. If the code comes back, proceed with the diagnostic process.
2) Check the sensor – Check the sensor and related components for signs of wear, damage, or corrosion. Test the sensor using a multimeter or oscilloscope to see if it produces the correct signal and if the circuit is open or shorted.
3) Check the circuit – Use a wiring diagram to check the circuit for continuity, shorts, and open circuits. Check the connectors and terminals for damage or corrosion. Repair or replace any component as necessary.
4) Check the alignment – Check the alignment of the crankshaft position sensor and adjust it if necessary. Restart the engine and check if the code is still present.

How to repair P2619?

Once you have determined the cause of P2619, you can repair it by:

1) Replacing the sensor – If the sensor is damaged, worn out or producing an incorrect signal, replace it with a new or refurbished one from a reputable supplier.
2) Repairing the wiring – If the wiring is damaged or corroded, repair the damaged areas using appropriate splices, connectors, or heat-shrink tubing.
3) Cleaning the sensor – If the sensor is dirty, clean it gently with a non-abrasive cleaner and a soft brush or cloth. Avoid damaging the sensor surface or the wires.
4) Adjusting the alignment – If the sensor is misaligned, adjust it using a factory-approved alignment tool or procedure.


1) Can P2619 cause engine failure?
P2619 alone may not cause engine failure, but it can result in poor engine performance, starting problems, or stalling. If left unattended, P2619 can lead to more severe engine issues, such as misfires, detonation, or damage to other components.

2) How often should I replace my crankshaft position sensor?
There is no set interval for replacing the crankshaft position sensor. Most manufacturers recommend replacing it if it shows signs of damage or fails the diagnostic test. Consult your vehicle owner’s manual for specific recommendations.

3) Can I drive with P2619?
Driving with P2619 may lead to poor engine performance, stalling, or safety issues. We recommend having your vehicle checked by a mechanic as soon as possible to diagnose and repair the root cause of the code.

4) How much does it cost to repair P2619?
The cost of repairing P2619 depends on the root cause of the code and the labor rates in your area. In general, replacing the sensor or repairing the wiring can cost between $100 and $500, including parts and labor.

5) Can I repair P2619 myself?
Repairing P2619 requires some technical knowledge and specialized tools. If you are not familiar with the procedure or lack the tools, we recommend taking your vehicle to a qualified mechanic for diagnosis and repair.


P2619 is a specific OBD-II code that indicates an issue with the crankshaft position sensor circuit. Although it can be triggered by different factors, diagnosing and repairing it requires following a standard procedure that involves testing the sensor, wiring, and alignment. By understanding what P2619 means and how to diagnose and repair it, you can ensure your vehicle performs optimally and safely. Remember to consult a qualified mechanic if you are not familiar with the diagnostic procedure or lack the necessary tools.
