P023D Honda Code - Turbocharger Boost Sensor/Manifold Absolute Pressure Sensor Incorrect Correlation
Quick Answer
The Barometric Pressure (BARO) Sensor, the Manifold Absolute Pressure (MAP) Sensor, and the Turbocharger Boost Sensor are equipped in the vehicle to detect air pressure conditions to the engine. Common causes include Faulty Turbocharger Boost Sensor, Turbocharger Boost Sensor harness is open or shorted, Turbocharger Boost Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P023D Honda Description
Malfunction determinations are done by the Powertrain Control Module (PCM) in two ranges by comparing the pressure sensor values. The Diagnostic Trouble Code (DTC) will be set when at range "B", the Turbocharger boost sensor or MAP sensor is abnormal if the difference of the two pressure sensor values are specified or more.
What are the Possible Causes of the DTC P023D Honda?
- Faulty Turbocharger Boost Sensor
- Turbocharger Boost Sensor harness is open or shorted
- Turbocharger Boost Sensor circuit poor electrical connection
- Faulty Manifold Absolute Pressure (MAP) Sensor
How to Fix the DTC P023D Honda?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P023D Honda code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P023D Honda Code
1. What does the OBDII code P023D mean on a Honda?
P023D indicates an "Turbocharger Boost Sensor/Manifold Absolute Pressure Sensor Incorrect Correlation," meaning the ECU has detected a mismatch between the readings from the boost pressure sensor and MAP sensor.
2. What are the common symptoms of the P023D code on a Honda?
Symptoms may include a check engine light, reduced engine performance, poor acceleration, black smoke from the exhaust, or the engine entering limp mode.
3. What causes the P023D code to appear on a Honda?
Common causes include a faulty turbo boost sensor, a malfunctioning MAP sensor, wiring issues, a vacuum or boost leak, or a failing turbocharger.
4. Can I drive my Honda with a P023D code?
It’s not recommended to drive with this code, as the vehicle may experience poor performance or damage to the turbocharger or engine components over time.
5. How do I troubleshoot the P023D code on a Honda?
Start by inspecting the turbo boost sensor and MAP sensor for damage or contamination, checking for vacuum or boost leaks, and testing the wiring and connectors for continuity or corrosion.
6. How do I fix the P023D code on a Honda?
Repairs may include replacing a faulty boost pressure sensor or MAP sensor, sealing vacuum or boost leaks, repairing damaged wiring, or in some cases, addressing turbocharger issues.
7. Can a dirty air filter cause the P023D code on a Honda?
While unlikely, a severely clogged air filter may restrict airflow and contribute to turbocharger or sensor issues, so it’s worth checking as part of the diagnosis.
8. How much does it cost to fix the P023D code on a Honda?
Costs vary depending on the cause, ranging from $100–$300 for sensor replacement to $1,000+ if turbocharger repairs are needed.
9. Can a P023D code be triggered by a software issue on a Honda?
Yes, in rare cases, outdated or corrupted ECU software can cause sensor miscommunication and trigger this code. Reflashing or updating the ECU may resolve it.
10. Will clearing the P023D code fix the issue on a Honda?
Clearing the code may turn off the check engine light temporarily, but the underlying problem must be resolved for the code not to return.
