Fault code P0170 Airtrek

[greg2k8]

I have been getting a P0170 code on my Airtrek. The check engine light triggers this code, but then the check engine light is on sometimes and off at other times.

Anybody having similar problems or can shed any light on this situation?

Thanks in advance.

Possible causes
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Tech notes
Dirty air filter, air filter housing or Mass Air Flow (MAF) sensor, or faulty MAF sensor are common causes for the P0170 code.

When is the code detected?
Fuel injection system does not operate properly or the amount of mixture ratio compensation is not correct

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption

P0170 MITSUBISHI Description
With 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 (http://engine-codes.com/articles/ecm.php) 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 http://engine-codes.com/articles/ecm.php judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

Not yet. It is intermittent. I used some better gas along with octane booster. I have not seen the check engine light come for awhile now, but still watching it.

[greg2k8]

Amsoil
