Code P0235 Ford Description
The P0235 diagnostic trouble code (DTC) for Ford vehicles indicates a malfunction in the Turbocharger/Supercharger Boost Sensor 'A' circuit. This sensor plays a crucial role in monitoring the boost pressure generated by the turbocharger or supercharger in the vehicle's engine. When the sensor detects an issue with the boost pressure, it triggers the P0235 code to alert the vehicle's onboard computer (ECU) that there is a problem.
Common Causes of P0235 Ford
- Faulty boost sensor: The boost sensor itself may be malfunctioning or failing, causing inaccurate readings.
- Wiring issues: Loose or damaged wiring in the boost sensor circuit can disrupt the signal between the sensor and the ECU.
- Turbocharger/supercharger issues: Problems with the turbocharger or supercharger, such as leaks or mechanical failures, can impact the boost pressure readings.
- ECU malfunction: A fault in the vehicle's ECU can also trigger the P0235 code by misinterpreting the sensor data.
Symptoms of P0235 Ford
- Loss of power: The vehicle may experience a noticeable decrease in power and acceleration, especially during high-speed driving or when climbing hills.
- Reduced fuel efficiency: A malfunctioning boost sensor can cause the engine to consume more fuel than usual, leading to decreased miles per gallon.
- Engine misfires: The engine may misfire, causing rough idling or hesitation when accelerating.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard, indicating a problem with the turbocharger/supercharger boost sensor circuit.
- Limp mode: In severe cases, the vehicle may enter a limp mode where power is limited to prevent engine damage.
How to Fix P0235 Ford
- Diagnose the issue: Use a scan tool to retrieve the trouble codes and perform a thorough inspection of the boost sensor circuit, wiring, and turbocharger/supercharger components.
- Replace the boost sensor: If the sensor is found to be faulty, replace it with a new one to restore accurate boost pressure readings.
- Repair wiring: Address any wiring issues by repairing or replacing damaged wires to ensure a secure connection between the sensor and the ECU.
- Check turbocharger/supercharger: Inspect the turbocharger or supercharger for any leaks, damage, or mechanical problems that could be affecting boost pressure.
- Clear codes and test drive: After completing the repairs, clear the DTCs from the ECU and test drive the vehicle to ensure that the issue has been resolved.
Cost to Fix P0235 Ford
The typical repair costs for addressing a P0235 code in a Ford vehicle can range from $200 to $500, depending on the specific cause of the issue and the parts/labour required for the repair. This estimate includes the cost of a new boost sensor, any necessary wiring repairs, and labour charges. However, it's important to note that actual repair costs can vary based on factors such as location, vehicle make and model, and the extent of the repairs needed. Additionally, diagnostic time and labour rates at auto repair shops can vary between $80 and $150 per hour, with rates potentially higher in metropolitan areas or at dealerships, and lower at independent shops. It's recommended to obtain quotes from local auto repair shops for a more accurate cost estimate.

-
hi i have a ford transit 2.0 tdci with code p0235 saying open circuit and the van goses in to get home mode just woundering what open circuit meens thank kev
-
Open circuit means either the boost pressure sensor is damage or the wires to the sensor are broken or not making good contact.
-
If it's wirering do I need to check all the wirering or is there a part of it that can cause a problem thanks
