This summary uses the existing diagnostic information shown in full below.
The car has a sensor that listens for knocking noises in the engine. This code means that one of these sensors isn't picking up enough signal from the engine on the right side.
The knock sensor detects vibrations caused by engine knocking. This code indicates that the signal from Knock Sensor 3 on Bank 2 is lower than expected.
The P13D0 code is triggered when the Engine Control Module (ECM) detects a low voltage signal from Knock Sensor 3 on Bank 2. This sensor is responsible for detecting engine knock or pinging, which can cause damage if not addressed.
• Check Engine Light illuminated
• Poor engine performance
• Increased fuel consumption
• Faulty knock sensor
• Wiring issues or poor connection
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the knock sensor.
• Test the knock sensor's resistance and voltage output.
• Replace the faulty knock sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Socket set
$150 - $400
Moderate
• Toyota Camry
• Honda Accord
• Ford F-150
• Regular maintenance checks
• Ensure proper fuel quality
• Inspect engine components regularly
Sensor Issue
• Avoid heavy acceleration until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check if the vehicle's powertrain warranty covers sensor issues.
Knock sensor issues have been common as vehicles rely more on electronic monitoring systems.
Moderate – Address promptly to avoid potential engine damage.
Ignoring this issue may lead to engine damage and increased emissions.
• Engine at operating temperature
• Vehicle in park or neutral
Typically located on the engine block, cylinder head, or intake manifold on Bank 2.
Q: What is a knock sensor?
A: A knock sensor detects engine knocking or pinging, which can harm the engine.
Q: Can I drive with a P13D0 code?
A: It's not recommended, as it may lead to engine damage if not addressed.
