Error Code P0242: What It Means & What To Do?

<<See All OBD Codes

P0242 error code can be defined as Turbocharger Boost Sensor B Circuit High. The boost pressure sensor would tell the engine control module that how much amount of boost is actually the turbocharger creates. Now when the powertrain control module would detect an incorrect signal from the boost pressure sensor, then the powertrain control module would set this trouble code. The vehicle may also be put into the “limp home mode” by the powertrain control module, limiting the power of the engine. This would protect the car engine from additional damage.

It is a generic OBD-II code which would start appearing when the engine control module would detect the intake boost pressure sensor B input circuit out of specifications which is possibly due to an open circuit or high voltage condition in the circuit from a short to the power.

What causes this problem with the Turbocharger Boost Sensor B Circuit High?

• DTC’s might be related to intake air temperature sensor, engine coolant temperature sensor, or 5 volt reference
• There can be some intermittent wiring problems
  
• The boost sensor "B" might be faulty
• Short circuit to voltage on sensor circuit
• Defective powertrain control module

1. Turbocharger - There can be some issues with the Turbocharger due to which you may see P0242 code appearing over and over again. Visit us to buy best quality Turbocharger online.
2. Turbo Boost Pressure Sensor - A lot of issues can arise do to defective Turbo Boost Pressure Sensor. Did you just see P0242 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
3. Air Intake Temperature Sensor - Faulty Air Intake Temperature Sensor can be the reason why P0242 code is flashing. Visit us to purchase top notch Intake Air Temperature Sensor online.
4. Engine Coolant Temperature Sensor - It is an important auto part which needs full care. A faulty Engine Coolant Temperature Sensor can be a reason behind the flashing up of P0242 code.
5. Powertrain Control Module - OBD Code P0242 can appear because of faulty Powertrain Control Module.
6. Engine Control Module - There can be some issues with the Engine Control Module due to which you may see P0242 code appearing over and over again. Visit us to buy best quality Engine Control Module online
   

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The check engine light can start appearing and code P0242 is set in the engine control module memory
• The engine control module can turn off the engine turbo boost and the engine will lack power
• The engine will lack power during acceleration

We have listed out some ways which would help you to correct the occurrence of OBD Code P0242. They are mentioned here as follows:

• The boost sensor should be replaced if it was open internally and not giving the correct input pressure voltage reading to the engine control module
• You can always repair the wiring harness if any shorts to power were found, and securing the harness from getting damaged
• If there is any broken connectors which are causing the short or open circuits, then it should be replaced
• Replacing a shorted engine control module, if it was shorted internally, and repairing the cause of the short

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of supercharger kit, crankshaft position sensor, turbo boost and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• The codes should be scanned and then document the freeze frame data in order to verify the problem
• The DTC codes should be cleared to verify whether the concern comes back
• You can always check the operation of the boost pressure sensor signal and compares it to the MAP sensor at engine idle to see if the readings are the same
• The turbo boost sensor wiring and connector should be properly inspected for any signs of shorts to power in the harness
• Make sure that you check the turbo boost sensor connector for corroded pins in the connector that may cause shorting of power in the signal circuit
• Carefully compare the readings to specifications on the sensor data scan

Common Mistakes When Diagnosing The P0242 Code

• It would be a good idea to disconnect the sensor to see if the short to power and code goes away or changes
• Make sure that you inspect the harness for melting from loose or hanging wire looms on the exhaust
