Code P0106 Infiniti Description
The P0106 code for Infiniti vehicles indicates a problem with the Manifold Absolute Pressure (MAP) sensor circuit's performance. The MAP sensor plays a crucial role in monitoring the pressure within the intake manifold and providing this information to the engine control module (ECM) for efficient fuel delivery and ignition timing. When the MAP sensor circuit performance is compromised, the ECM may not receive accurate data, leading to potential issues with fuel mixture, engine performance, and emissions control.
Common Causes of P0106 Infiniti
- Faulty MAP sensor
- Damaged or corroded wiring/connectors in the MAP sensor circuit
- Vacuum leaks in the intake manifold or hoses
- Clogged or dirty MAP sensor
- ECM software or hardware issues
Symptoms of P0106 Infiniti
- Rough idling or fluctuating idle speed
- Decreased fuel efficiency
- Engine hesitation or stumbling during acceleration
- Engine stalling
- Illuminated check engine light
How to Fix P0106 Infiniti
- Begin by performing a thorough inspection of the MAP sensor, wiring, and connectors for any visible damage or corrosion.
- Test the MAP sensor using a multimeter to check for proper voltage output.
- Check for vacuum leaks in the intake manifold and hoses, repairing or replacing any damaged components.
- Clean the MAP sensor using electronic cleaner to remove any dirt or debris that may be affecting its performance.
- If the issue persists, consider replacing the MAP sensor with a new, OEM-quality part.
Cost to Fix P0106 Infiniti
The cost of repairing a P0106 code on an Infiniti vehicle can vary depending on the specific model, location, and labor rates at the auto repair shop.

Frequently Asked Questions about P0106 Infiniti Code
1. What does the OBDII code P0106 mean on an Infiniti?
P0106 indicates a "Manifold Absolute Pressure (MAP) Circuit Performance Problem," meaning the MAP sensor readings are inconsistent or outside the expected range.
2. What are the common symptoms of code P0106 on an Infiniti?
Symptoms may include poor engine performance, rough idling, stalling, reduced fuel efficiency, and sometimes an illuminated check engine light.
3. What causes the P0106 code to appear in an Infiniti?
Common causes include a faulty MAP sensor, vacuum leaks, clogged air intake, damaged wiring or connectors, or issues with the engine control module (ECM).
4. Can a dirty throttle body cause the P0106 code on an Infiniti?
Yes, a dirty or clogged throttle body can disrupt airflow, potentially causing MAP sensor readings to be inaccurate and triggering the P0106 code.
5. How do you diagnose the P0106 code on an Infiniti?
Diagnosis involves checking the MAP sensor for proper operation, inspecting vacuum hoses for leaks, testing wiring and connectors, and ensuring the ECM is functioning correctly.
6. Is it safe to drive an Infiniti with the P0106 code?
Driving with the P0106 code is not recommended, as it can lead to poor engine performance and potential damage if the issue persists.
7. How can I fix the P0106 code on my Infiniti?
Repairs may include replacing the MAP sensor, fixing vacuum leaks, cleaning the throttle body, repairing damaged wiring, or reprogramming the ECM if necessary.
8. Can a bad MAP sensor alone trigger the P0106 code on an Infiniti?
Yes, a faulty MAP sensor is a common cause of the P0106 code, as it directly affects the manifold pressure readings sent to the ECM.
9. Will clearing the P0106 code fix the problem on an Infiniti?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
10. What tools are needed to troubleshoot the P0106 code on an Infiniti?
You’ll need an OBD-II scanner, a multimeter for electrical testing, and basic tools to inspect and clean or replace components like the MAP sensor or throttle body.
