P023D 2018 Honda CR-V 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 2018 Honda CR-V 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 2018 Honda CR-V?
- 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 2018 Honda CR-V?
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 2018 Honda CR-V 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 2018 Honda CR-V Code
1. What does the OBDII code P023D mean on a 2018 Honda CR-V?
P023D indicates a discrepancy between the readings of the Turbocharger Boost Sensor and the Manifold Absolute Pressure (MAP) Sensor, suggesting they are not correlating as expected.
2. What are the symptoms of code P023D in a 2018 Honda CR-V?
Symptoms may include reduced engine performance, poor acceleration, increased fuel consumption, illuminated check engine light, and possibly entering limp mode.
3. What causes the P023D code on a 2018 Honda CR-V?
Common causes include a faulty Turbocharger Boost Sensor or MAP Sensor, wiring or connector issues, vacuum leaks, or a malfunctioning turbocharger.
4. Can a dirty air filter cause the P023D code?
Yes, a clogged or dirty air filter can restrict airflow, potentially causing an incorrect correlation between the sensors.
5. How do I diagnose the P023D code on my 2018 Honda CR-V?
Start by inspecting the wiring and connectors for damage, checking the sensors for proper operation, and using a scan tool to compare readings from the Turbocharger Boost Sensor and MAP Sensor.
6. Can I still drive my 2018 Honda CR-V with the P023D code?
Driving with the P023D code is not recommended, as it can lead to reduced performance, increased fuel consumption, and potential damage to the engine or turbocharger.
7. How much does it cost to fix the P023D code on a 2018 Honda CR-V?
Repair costs vary, but sensor replacement typically ranges from $100 to $400, while turbocharger repairs can be significantly more expensive if needed.
8. Can a vacuum leak cause the P023D code?
Yes, a vacuum leak can create pressure inconsistencies that lead to incorrect sensor correlation and trigger the P023D code.
9. Will clearing the P023D code fix the issue?
Clearing the code will reset the check engine light temporarily, but the underlying problem must be addressed to prevent the code from returning.
10. Do I need to replace the turbocharger to fix the P023D code?
Not necessarily. The issue may be with the sensors, wiring, or a simple airflow restriction. A thorough diagnosis is essential before replacing the turbocharger.
