P0236 Fault Code

P0236 OBD-II Trouble Code Short Description

Turbocharger Boost Sensor A Range/Performance

What does trouble code P0236 mean?

The P0236 fault code is related to the turbocharger boost sensor. This sensor is responsible for monitoring the amount of pressure that the turbocharger is providing to the engine. The code indicates that the sensor reading is outside of the expected range or is not performing properly.

This can be caused by a variety of issues, such as a faulty sensor, wiring problems, or problems with the turbocharger itself. In some cases, the issue may be related to a lack of proper maintenance, such as dirty air filters or clogged fuel injectors.

To resolve the issue, the first step is to have the vehicle diagnosed by a qualified mechanic. They will be able to determine the root cause of the problem and make the necessary repairs. This may involve replacing the sensor, repairing or replacing wiring, or repairing the turbocharger.

It is important to address this issue promptly, as a malfunctioning turbocharger can cause engine damage over time. In addition, a decrease in engine performance can negatively impact fuel efficiency and overall driving experience.

What are the symptoms of the P0236 code?

Here are some possible symptoms of a P0236 fault code in cars:

  • Check Engine Light (CEL) is on
  • Reduced power or acceleration
  • Poor fuel economy
  • Rough engine idle
  • Hesitation or surging during acceleration
  • Turbocharger not functioning properly or making unusual noises
  • Black smoke coming from the exhaust

Note that not all symptoms may be present, and some symptoms may be more severe than others depending on the vehicle.


What causes the P0236 code?

The P0236 fault code indicates that there is a problem with the turbocharger boost sensor A circuit. This code is triggered when the powertrain control module (PCM) detects that the voltage or signal from the boost sensor is not within the expected range. The possible causes for this fault code include a faulty boost sensor, wiring or connector issues in the sensor circuit, a vacuum leak in the turbocharger system, or a failed turbocharger. The correct diagnostic procedure should be followed to identify and fix the underlying cause of this fault code.

Possible Solutions

How to fix P0236?

Possible solutions for fixing P0236 Turbocharger Boost Sensor A Range/Performance fault code include:

  1. Check the turbocharger and the intake system for any leaks or damages. Repair or replace any damaged components.
  2. Inspect and clean the turbocharger boost sensor and its wiring connections. Make sure they are not corroded, damaged, or loose.
  3. Perform a diagnostic scan of the engine and the turbocharger system to identify any additional faults or issues that may be causing the P0236 code. Address any other problems as needed.
  4. Reset the fault codes and test drive the vehicle to verify if the P0236 code returns. If it does, further troubleshooting may be required, such as testing the sensor with a multimeter or using a scan tool to monitor the sensor's readings while driving.
