Hello! good night, at this time we will write an article about Error P0332 – how to fix?
P0332 Code Definition
If the knock sensor 2 circuit gives a low input, the PCM (Powertrain Control Module) registers P0332 and illuminates the Check Engine light.
What does the code P0332 mean
The knock sensor is designed to signal the PCM when the engine beeps. If the PCM receives a knock sensor reading that is too low, it will not be able to accurately ping the correct signal and the PCM will not be able to correct the problem. This can result in increased emissions and other engine problems.
What causes the code P0332?
When the P0332 code is stored, the most common causes are:
- Knock sensor damaged
- Malfunction in the knock sensor circuit or its connectors
- Air-fuel ratio too lean
- Problem in the cooling system
- Faulty EGR (exhaust gas recirculation) system.
What are the symptoms of the P0332 code?
In some rare cases, there will be no symptoms other than the Check Engine light being turned on. In most cases, however, you may notice one or more of the following symptoms:
- Engine whistle when accelerating.
- Increased engine heating during normal operation
- No power or loss of power
How can a mechanic diagnose the P0332 code?
After checking the code with the OBD-II scanner, the mechanic will start by inspecting the sensor and its circuits. Then, he will likely use an ohmmeter and other diagnostic tools to test the circuit, connectors, and other related components.
After each test and / or repair, they clear the PCM code and retest the system by starting the vehicle. In some cases, they will conduct a short or longer test drive to make sure there is no intermittent problem that needs to be addressed.
Common errors when diagnosing the P0332 code
The most common errors related to this code are failure to check and diagnose the root cause of the problem. In some cases, the knock sensor is replaced when the problem was actually the wiring or connectors. In other cases, the problem may be with the cooling system or the EGR system, in which case replacing the knock sensor will not resolve the issue.
How serious is the P0332 code?
Motor ping can seriously affect the motor’s ability to run cleanly and efficiently. If the knock sensor is malfunctioning, the PCM cannot get the correct information from it to predict and correct the problem. This can lead to an engine that runs poorly, overheats, has lower fuel efficiency, and other problems as well.
What repairs can fix the P0332 code?
Some of the fixes that most often fix code P0332 are:
- Replace frayed or damaged wires and connectors in the sensor circuit.
- Make sure the sensor and circuit are properly grounded.
- Replace the knock sensor
- Correct the cause in the EGR or cooling system
- Replace or reprogram PCM (rarely)
Additional considerations for code P0332
Even if you do not notice any other problems or symptoms with your vehicle, the P0332 code will illuminate the Check Engine light. If this light illuminates during the OBD-II exhaust emission test, the vehicle will not pass the test. In most states and with most vehicles, this means you will not be able to legally register a vehicle or renew it. Fixing this problem early can prevent many headaches as well as more complex and costly road repairs.
