P0332 – OBD-II DTC

OBD-II DTC P0332 – Knock Sensor 2 Circuit Range/Performance (Bank 2)

DTC P0332 meaning

DTC P0332 refers to a problem with the Knock Sensor 2 circuit in Bank 2 of the engine. The knock sensor is responsible for detecting engine knock or pinging, which can indicate abnormal combustion. When the Engine Control Module (ECM) detects that the signal from Knock Sensor 2 is out of range or not performing as expected, it triggers this diagnostic trouble code (DTC).

DTC P0332 symptoms

Common symptoms associated with DTC P0332 may include:

• Illuminated check engine light
• Decreased engine performance
• Increased fuel consumption
• Engine knocking or pinging sounds
• Rough idling or stalling

DTC P0332 causes

Several factors can lead to the triggering of DTC P0332, including:

• Faulty Knock Sensor 2
• Wiring issues, such as shorts or open circuits in the knock sensor circuit
• Corroded or loose connectors
• Engine mechanical issues, such as excessive engine noise
• Faulty Engine Control Module (ECM)

DTC P0332 seriousness

The seriousness of DTC P0332 can vary. While it may not cause immediate engine failure, it can lead to long-term engine damage if left unaddressed. Ignoring this code can result in:

• Increased engine wear
• Potential for engine knocking
• Reduced fuel efficiency
• Failure to pass emissions tests
