The crankshaft position sensor or TDC sensor connector has been detected as disconnected or experiencing an open circuit. This sensor is critical for engine timing and fuel injection synchronization.
Safety Warning
Engine will not start or will stall immediately if sensor signal is lost. Vehicle is not drivable until repaired.
Common Causes
45%
Disconnected or loose crankshaft position sensor connector
25%
Damaged crankshaft position sensor wiring harness
20%
Failed crankshaft position sensor internal open circuit
10%
Corroded or damaged connector terminals
Diagnostic Steps
1
Step 1: Locate and visually inspect crankshaft position sensor connector for proper seating
2
Step 2: Check connector terminals for corrosion, damage, or pushed-back pins
3
Step 3: Measure resistance across sensor terminals (typically 200-900 ohms depending on type)
4
Step 4: Check continuity of wiring from sensor to PCM on both signal and ground circuits
5
Step 5: Verify sensor air gap if adjustable type (typically 0.020-0.050 inches)
Estimated Repair Cost
$80 - $350
