Crankshaft Position Sensor Circuit High Voltage
The P2619 code indicates that the Engine Control Module (ECM) has detected a voltage signal from the crankshaft position sensor that is higher than the expected range. This sensor is critical for engine timing and fuel injection. A high voltage condition can be caused by a short to power in the sensor circuit, a faulty sensor, or a damaged wiring harness. This code may prevent the engine from starting or cause it to run poorly.
01. Most Common Causes
- Short to voltage in the crankshaft position sensor circuit
- Faulty crankshaft position sensor
- Damaged wiring or connector
- ECM internal fault (rare)
02. Symptoms You Will Notice
- Engine may not start
- Engine stalls or runs rough
- Check Engine Light illuminated
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to confirm the code and check for related codes.
Step 2: Visually inspect the crankshaft position sensor wiring and connector for damage or corrosion.
Step 3: Measure voltage at the sensor signal wire with the ignition on; should be around 5V reference. If higher, suspect short to power.
Step 4: Test the sensor resistance and compare to specifications; replace if out of range.
Step 5: If wiring and sensor are good, test the ECM for proper signal processing.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The engine may stall or fail to start, leading to a breakdown or accident.
How much does it cost to fix?▼
Typically $50-$150 for diagnosis and sensor replacement, but costs can vary if wiring repairs are needed.
