Code P0238 2017 Honda CR-V Description
The P0238 diagnostic trouble code (DTC) for a 2017 Honda CR-V indicates a problem with the Turbocharger Boost Sensor Circuit High Voltage. In turbocharged vehicles like the Honda CR-V, the turbocharger boosts the engine's power output by forcing more air into the combustion chamber. The turbocharger boost sensor measures the pressure of the air entering the engine and sends this information to the engine control module (ECM).
Common Causes of P0238 2017 Honda CR-V
- Faulty turbocharger boost sensor: The sensor itself may be malfunctioning, sending incorrect voltage signals to the ECM.
- Damaged wiring: The wiring connecting the turbocharger boost sensor to the ECM may be frayed, corroded, or damaged, leading to high voltage readings.
- ECM issues: A malfunctioning ECM could misinterpret the signals from the turbocharger boost sensor, triggering the P0238 code.
- Boost leaks: Any leaks in the turbocharger system, such as in the intercooler or intake piping, can cause incorrect boost pressure readings.
- Overboost condition: If the turbocharger is producing too much boost pressure, it can lead to a high voltage signal from the sensor.
Symptoms of P0238 2017 Honda CR-V
- Reduced engine power: The vehicle may experience a lack of power or acceleration due to incorrect boost pressure readings.
- Check Engine Light: The Check Engine Light may illuminate on the dashboard to indicate a problem with the turbocharger boost sensor circuit.
- Poor fuel efficiency: The engine may consume more fuel than usual due to incorrect air/fuel mixture caused by the high voltage signal.
- Rough idling: The engine may idle roughly or inconsistently due to the incorrect boost pressure readings.
- Engine stalling: In severe cases, the engine may stall due to the incorrect information being sent to the ECM.
How to Fix P0238 2017 Honda CR-V
- Diagnose the issue: Use a scan tool to read the DTC and check the turbocharger boost sensor circuit for high voltage readings.
- Inspect wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the turbocharger boost sensor: Test the sensor using a multimeter to ensure it is functioning correctly. Replace if faulty.
- Check for boost leaks: Inspect the turbocharger system for any leaks that could be causing incorrect boost pressure readings.
- Reset the ECM: Clear the DTC and reset the ECM to see if the issue persists. If the code returns, further diagnosis may be required.
Cost to Fix P0238 2017 Honda CR-V
The cost of repairing a P0238 code on a 2017 Honda CR-V can vary depending on the specific cause of the issue. In general, the cost of replacing a turbocharger boost sensor can range from $100 to $300, including parts and labor. If the issue is related to wiring repairs or ECM diagnostics, the cost may increase. It's important to factor in diagnostic time and labor rates, which can vary between $80 and $150 per hour at most auto repair shops. It's recommended to consult with a qualified mechanic to get an accurate estimate for the repair.

Frequently Asked Questions about P0238 2017 Honda CR-V Code
1. What does the OBDII code P0238 mean on a 2017 Honda CR-V?
P0238 indicates a "Turbocharger Boost Sensor Circuit High Voltage," meaning the Engine Control Module (ECM) has detected a voltage signal from the boost pressure sensor that is higher than expected.
2. What are the common symptoms of the P0238 code in a 2017 Honda CR-V?
Symptoms may include reduced engine performance, poor acceleration, the engine going into limp mode, excessive exhaust smoke, and the Check Engine Light being illuminated.
3. What causes the P0238 code to appear on a 2017 Honda CR-V?
Common causes include a faulty boost pressure sensor, damaged or corroded wiring, a short circuit, a defective ECM, or issues with the turbocharger system.
4. Can I drive my 2017 Honda CR-V with a P0238 code?
While the car may still run, driving with this code can lead to reduced performance, potential turbocharger damage, and increased fuel consumption. It’s best to address the issue as soon as possible.
5. How can I diagnose the P0238 code on my 2017 Honda CR-V?
Diagnose by using an OBDII scanner to confirm the code, inspecting the boost sensor and wiring for damage, and testing the sensor’s voltage output with a multimeter.
6. How do I fix the P0238 code on a 2017 Honda CR-V?
Repairs may include replacing a faulty boost pressure sensor, repairing damaged wiring or connectors, and checking for issues in the turbocharger system.
7. Where is the boost pressure sensor located on a 2017 Honda CR-V?
The boost pressure sensor is typically located near the intake manifold or on the intercooler piping, depending on the engine layout.
8. What tools are needed to troubleshoot the P0238 code on a 2017 Honda CR-V?
You’ll need an OBDII scanner, a multimeter for voltage testing, and basic hand tools to inspect and potentially replace the boost sensor or wiring.
9. Can a dirty air filter cause the P0238 code on a 2017 Honda CR-V?
