This summary uses the existing diagnostic information shown in full below.
The car's computer isn't getting enough information from a sensor that helps it know when to fire the engine's spark plugs. It's like trying to play a song but missing some notes.
The engine control module (ECM) is not receiving the expected number of pulses from the high-resolution timing reference signal A.
The P0372 code indicates that the ECM has detected an insufficient number of pulses from the high-resolution timing reference signal A. This signal is crucial for the ECM to determine the precise timing for fuel injection and ignition. A disruption in this signal can lead to performance issues.
• Engine misfires
• Poor acceleration
• Check Engine Light illumination
• Faulty crankshaft position sensor
• Damaged wiring or connectors
• ECM malfunction
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the crankshaft position sensor and its wiring.
• Check for any loose or damaged connectors.
• Replace the crankshaft position sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Socket set
$150 - $500
Moderate
• Chevrolet Silverado
• Ford F-150
• Dodge Ram
• Regular maintenance checks
• Timely replacement of sensors
• Keeping electrical connections clean and secure
Sensor Issue
• Address the issue promptly to avoid further engine damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle manufacturer for specific warranty coverage on sensors and ECM.
This code has been associated with sensor failures and wiring issues in older vehicles, particularly those with high mileage.
Moderate – The vehicle may still be operable, but performance issues could worsen if not addressed.
Ignoring this code may lead to increased emissions and potential engine damage.
• Engine running
• Vehicle at operating temperature
The crankshaft position sensor is typically located near the bottom of the engine, close to the crankshaft pulley.
Q: Can I drive with a P0372 code?
A: It's possible to drive, but it's not recommended as it may lead to further engine issues.
Q: How do I reset the P0372 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code may return.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
