Cost of diagnosing the P0175 2006 NISSAN ALTIMA SEDAN code
Labor: 1.0The cost of diagnosing the P0175 2006 NISSAN ALTIMA SEDAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.)
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption
P0175 2006 NISSAN ALTIMA SEDAN MeaningWith the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the MIL (2 trip detection logic).
