P0332 password definition

If the knock sensor 2 circuit offers a short input signal, the PCM (powertrain control module) record a P0332 code and illuminate the inspect Engine Light.

What the P0332 password means

The hit sensor’s objective is come signal come the PCM as soon as the engine is pinging. If the PCM is receiving a reading from the hit sensor the is also low, it will certainly not be able to accurately send the proper signal of a ping, and also the PCM will not have the ability to correct the problem. This can an outcome in higher emissions and other troubles for the engine, together well.

What reasons the P0332 code?

When a P0332 password is stored, the many common causes are:

A faulty hit sensorA error in the knock sensor circuit or that connectorsAn air/fuel ratio that’s too leanA trouble with the cooling systemA defective EGR (exhaust gas recirculation) system

What space the symptoms of the P0332 code?

Pinging in the engine when acceleratingIncreased engine heat under common operationLack or lose of power

How does a mechanic diagnose the P0332 code?

After verifying the code v an OBD-II scanner, the mechanic will then begin with a intuitive inspection that the sensor and its circuit. They will then likely use one ohmmeter and also other diagnostic devices to test the circuit, connectors, and also other associated components.

After each test and/or repair, they will clear the code from the PCM and retest the device by transforming the automobile on. In some cases, they will certainly take a short or extended test journey to ensure that there is not an intermittent problem that requirements to it is in addressed.

This can lead to an engine that runs rough, overheats, has reduced fuel efficiency, and other problems, as well.

What repairs can fix the P0332 code?

Some of the repairs the most typically fix a P0332 code are:

Ensuring the the sensor and circuit are effectively groundedReplacing the punch sensorAddressing the root cause in the EGR or cooling systemReplacing or reprogramming the PCM (rare)
