P0242 Code - Turbocharger/Supercharger Boost Sensor 'B' Circuit High

What Does P0242 Mean?

Regarding the P0242 code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket. This is done most easily from below the car in the area near the oil filter. When you see P0242 engine fault code on your engine code reader this description will help you.

What are the common causes of P0242 ?

• A large air leak at or near the number one oxygen sensor would also cause a lean mixture.
• Faulty IMRC actuator relay (if equipped)
• Defective ECU strategies or components will prevent proper regeneration

How do you troubleshoot P0242 ?

• Replacing the boost sensor if it was open internally and not giving the correct input pressure voltage reading to the ECM
• Repairing the wiring harness if any shorts to power were found, and securing the harness from getting damaged (Check the ECM for voltage spike damage)
• Replacing any broken connectors causing the short or open circuits
• Replacing a shorted ECM, if it was shorted internally, and repairing the cause of the short
