P023D 2020 Honda CR-V Code - Turbocharger Boost Sensor/Manifold Absolute Pressure Sensor Incorrect Correlation

P023D indicates an issue where the Turbocharger Boost Sensor and the Manifold Absolute Pressure (MAP) Sensor readings are not correlating as expected, suggesting a potential problem with the sensors, wiring, or turbocharger system.

Symptoms may include reduced engine performance, lack of power during acceleration, the Check Engine Light turning on, and possibly poor fuel economy.

Common causes include a faulty boost pressure sensor, a malfunctioning MAP sensor, wiring issues like damaged or corroded connectors, a leak in the intake system, or problems with the turbocharger itself.

It’s possible to drive the vehicle short distances, but prolonged driving with this issue can lead to further engine damage or reduced performance. It’s best to address the issue promptly.

A mechanic will use a scan tool to check live sensor data, inspect the wiring and connectors for damage, and perform a visual inspection of the intake and turbocharger system for leaks or physical damage.

Repairs may include replacing a faulty boost pressure sensor or MAP sensor, repairing damaged wiring or connectors, fixing intake system leaks, or addressing turbocharger issues.

The cost can vary depending on the root cause, but sensor replacement typically ranges from $100 to $300, while turbocharger repairs or replacements can be significantly more expensive.

A clogged or dirty air filter can restrict airflow and indirectly contribute to the issue, but it’s not a primary cause of the P023D code. However, it’s worth checking during diagnosis.

Clearing the code may temporarily turn off the Check Engine Light, but unless the underlying issue is resolved, the code is likely to return.

Regular maintenance, including inspecting turbo-related components, ensuring proper sensor operation, and keeping the intake system clean and sealed, can help prevent this issue.
