What does P0236 mean?
The boost pressure sensor reads intake pressure after the turbocharger.
The circuit is electrically intact, but the reading does not make sense for the operating conditions. Sometimes the sensor is fine and is reporting a real problem.
Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.
Symptoms
- Check engine light
- Reduced power or limp mode
- Black smoke on diesels
Common causes
- Sensor reading that does not match other sensors (a skewed or slow sensor)
- Mechanical problem the sensor is correctly reporting
- Restricted or leaking hose/port to the sensor
- High resistance in the connector
- Failed boost sensor
- Oily or plugged sensor port
- Wiring problems
How to diagnose P0236
- Compare the live reading with related sensors and with known values (key on, engine off and at idle).
- Inspect hoses, ports and the connector for damage, oil or corrosion.
- Only replace the sensor after ruling out the real-world condition it measures.
- Key on, engine off, the reading should match barometric pressure.
- Check the port for oil and carbon.
How to fix it
- Clean the port
- Replace the sensor
- Repair wiring
Estimated repair cost
Likely repairs for P0236 run from about $100 to $350, depending on the cause.
| Repair | Typical range (parts + labor) |
|---|---|
| Diagnostic fee (scan + testing) | $100 - $200 |
| Boost/MAP sensor (diesel) | $100 - $350 |
These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.
How serious is P0236?
Moderate severity
Drivable with care; power will likely be limited.
P0236 FAQ
What does P0236 mean?
P0236 stands for "Turbocharger/Supercharger Boost Sensor "A" Circuit Range/Performance". The boost pressure sensor reads intake pressure after the turbocharger.
Can I drive with a P0236 code?
Drivable with care; power will likely be limited.
How much does it cost to fix P0236?
It depends on the cause. The likely repairs for P0236 range from about $100 to $350 at an independent shop in the US, plus a diagnostic fee of roughly $100-$200. These are rough estimates; dealer prices and some vehicles run higher.
What is the most common cause of P0236?
The most common causes are: sensor reading that does not match other sensors (a skewed or slow sensor); mechanical problem the sensor is correctly reporting; restricted or leaking hose/port to the sensor.
