P2619 code definition
This OBD-II DTC represents Crank Position Signal Output Circuit Open.
What the P2619 code means
The crankshaft is a crucial component in your vehicle’s ability to move. The crank position sensor (CPS) sends signals to the PCM (powertrain control module) about the position of the crankshaft, which are interpreted by the PCM as voltage readings. These readings are used to determine engine timing, fuel delivery, and other vital operational details. When the crank position signal falls outside of the normal parameters, or is absent altogether, the vehicle’s computer will store this code.
What causes the P2619 code?
A number of conditions may contribute to this fault:
- A faulty CPS
- Corroded or loose CPS wiring or connectors
- Damaged crankshaft reluctor rings or teeth
- Broken timing belt or chain which is wound around the timing gears
- A faulty PCM (rare)
What are the symptoms of the P2619 code?
Along with a stored code and illuminated Check Engine Light, you may experience a no-start condition, rough idling, rough acceleration, engine misfires, poor engine performance, and/or decreased fuel efficiency.
How does a mechanic diagnose the P2619 code?
Diagnosis may involve:
- Scanning the vehicle’s computer to verify the code, record freeze frame data, and check for concurrent codes
- Clearing the codes then test driving the vehicle to see if they return
- Visually inspecting the wiring harness and connectors for damage or loose connections
- Testing the crank sensor resistance and voltage to see if they match manufacturer specifications
- Observing distributor, crankshaft, and camshaft sensor waveform patterns with an oscilloscope
- Testing the RPM signal with the engine cranked or running
Common mistakes when diagnosing the P2619 code
Visual inspection of timing components is often overlooked. If the CPS and its circuitry are all functioning properly, timing parts should be inspected for broken reluctor rings, damaged gear teeth, and other abnormalities.
How serious is the P2619 code?
P2619 can have a serious effect on the vehicle’s ability to run. Even if you aren’t experiencing any severe symptoms, multiple systems may be affected by a crank position signal problem, including fuel injection and the timing of engine firing. In order to prevent engine problems which could compromise your safety, as well as further damage, you should have the problem checked out by a qualified mechanic as soon as possible.
What repairs can fix the P2619 code?
One or more of the following fixes may be necessary:
- CPS replacement
- Repair of wiring or connectors
- Timing belt or chain replacement
- Reluctor ring replacement or repair to damaged gear teeth
Additional comments for consideration regarding the P2619 code
There are two different kinds of systems when it comes to crankshaft position. The first only uses crankshaft position to detect misfires, rather than to dictate spark timing or ignition. The second type does use crankshaft position for ignition control and spark timing. CPS problems in the first type of system won’t typically cause a no-start condition. If your vehicle utilizes the second type of system, you’ll be much more likely to experience serious conditions like no-start, or poor engine performance.
If the code fails to set again after the vehicle’s computer has been cleared, this can be a sign of an intermittent condition. These can be difficult to diagnose, and may have to be allowed to get worse before the code sets consistently, allowing for a thorough diagnostic procedure to be carried out. According to professional technicians, wiring and connector problems are almost always the cause of an intermittent CPS signal condition.
If the CPS needs replacing, both that and the camshaft position sensor should be done at the same time. The same is true of reluctor rings – these things should be replaced in sets so that all components wear at the same rate.
