How do I fix code P0237?
What repairs can fix the P0237 code?
- Replacing the boost sensor if it is shorted internally and not giving the correct input pressure reading to the ECM.
- Repairing the wiring harness if any shorts are found, and securing the wiring harness from excessive heat.
- Cleaning or replacing any corroded connections.
Where is the turbo boost sensor?
intake pipe
The boost pressure sensor is located inside the intake pipe in front of the throttle valve. The Sensor measures the pressure and sends the data to the engine management system.
What does a turbo boost sensor do?
The Turbo Boost Sensor measures turbo manifold pressure to the ECM, and is used to calculate air density and the required fuel delivery for optimum combustion. If it fails, the system may not add fuel under boost and can result in loss of power and possible engine damage.
What does it mean when it says turbocharger boost sensor high?
It’s a generic trouble code which applies to all turbocharged vehicles. Vehicles of different manufacturer and model of course, have different definitions and specifications on troubleshooting and repair. For generic vehicles for example, they call this error code Turbocharger/Supercharger Boost Sensor “A” Circuit High.
How does the PCM control the turbocharger?
The PCM uses boost control solenoid to control the amount of pressure produced by the turbocharger, and simultaneously use the boost pressure sensor to verify the correct boost pressure. Zero boost sensor pressure means around 0.5V, while maximum boost is at 4.5V.
What does the p0238 code on the turbocharger boost sensor mean?
P0238 is a diagnostic trouble code (DTC) for “Turbocharger Boost Sensor A Circuit High”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0.
How many volts does a boost pressure sensor have?
The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The ECM supplies 5 volts to the boost pressure sensor on the 5-volt reference 2 circuit and provides a ground on a low reference circuit.
