This summary uses the existing diagnostic information shown in full below.
This means that the car's computer is getting a very high signal from one of the sensors that listens for knocking noises in the engine. It's like when you hear a loud noise and cover your ears. The car thinks something is too loud, but it might be a mistake.
The engine control module (ECM) has detected a high voltage signal from knock sensor 4 on bank 2, indicating a possible issue with the sensor or wiring.
The P13D5 code is triggered when the ECM detects a higher than normal voltage from the knock sensor 4 circuit on bank 2. Knock sensors are used to detect engine knocking, which is a type of abnormal combustion. A high circuit signal could indicate a short to voltage, a faulty sensor, or a wiring issue.
• Check engine light is on
• Possible engine performance issues
• Unusual engine noises
• Faulty knock sensor 4
• Wiring issues such as a short to voltage
• Faulty ECM
ECM: Engine Control Module
DTC: Diagnostic Trouble Code

• Inspect the wiring and connectors for damage
• Test the knock sensor for proper operation
• Replace the faulty knock sensor
• Repair or replace damaged wiring
• Reprogram or replace the ECM if necessary
• OBD-II scanner
• Multimeter
• Socket set
$150 - $400
Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance checks
• Avoiding poor quality fuel
• Timely repair of any engine issues
Sensor Issue
• Do not ignore the check engine light
• Consult a professional mechanic if unsure
• Regularly check for recalls or service bulletins
Check with your vehicle manufacturer for specific warranty coverage on emissions-related components.
Knock sensor issues have been a common diagnostic trouble code (DTC) in vehicles with advanced engine management systems.
Moderate – Addressing this issue promptly can prevent engine damage.
Driving with a malfunctioning knock sensor can lead to engine damage and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle in a quiet environment to detect knocking
The knock sensor is typically located on the engine block, cylinder head, or intake manifold.
Q: What does a knock sensor do?
A: A knock sensor detects engine knocking or pinging, which can indicate improper combustion.
Q: Can I drive with a P13D5 code?
A: It's not recommended to drive for an extended period with this code as it can lead to engine damage.
