What is P0235 : Engine Error code Causes Explained
This guide, covers the P0235 engine error code, its common causes, potential risks, and how it affects vehicle performance. Understanding this code helps car owners diagnose issues and take timely action to prevent serious engine damage
How to Identify a DTCs Number
The P0235 engine error code refers to a fault in the turbocharger boost sensor A circuit.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
To identify a DTC like P0235, you need an OBD-II scanner connected to the vehicle’s diagnostic port. The scanner communicates with the ECM to retrieve stored trouble codes. It then displays the exact DTC number along with a brief description of the fault for proper diagnosis.
Causes of P0235 Error Code:
- Shorted or Open Harness:
A wiring short or break between the boost pressure sensor and ECM can cause a faulty signal. - Poor Electrical Connections:
Loose or corroded sensor circuit connections can cause intermittent or incorrect readings. - Sensor Malfunction:
The sensor itself may be failing to accurately measure boost pressure, leading to the code. - Obstructed or Dirty Sensor.
A clogged or dirty sensor can also affect its readings. - Engine Overheating:
In some cases, an engine overtemperature issue can trigger this code.
Risk Level of P0235 Error Code:
The P0235 engine error code, which indicates a malfunction in the turbocharger or supercharger boost sensor circuit, is considered high risk because it can significantly affect engine performance and fuel efficiency.
Common Car Brands Affected by P0235 Code:
