Question about 2000 Mitsubishi Galant

1 Answer

I have a 2000 Mitsubishi Galant and it's reading a P0170 code. I had the oxygen sensor replaced a year ago and one mech thinks it's the fuel tank pressure sensor. How can I access this or fix the problem. It runs great but when I start it, it winds once or twice but always kicks in.

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
If you have a K&N filter, the code may actually be caused because it was over oiled.

If you have changed out the parts and still get the codes you probably need to have the ECM reset. The dealer can do that for you or a repair shop that has the scan tool.

Sometimes you can clear cars computer by taking off battery cable,maybe it will work for you, leave battery cable off about 10 mins. and try that. Just a fast thought, Hope it works for you. Billy Wyatt

I have a 99 mitsubishi galant its reading a code po170 sumthin bout gas wat does that mean


P0170....Fuel Trim (Bank 1)

from reading the code it is about fuel and its the mixture isnt correct ,this i think is being caused by a faulty O2 sensor on bank one but as iam in europe and out gallants are normally a 4 cyl engine i am afraid i couldnt tell you whats bank one weither its the left side or the right side but if you can find out what side is bank one then its just a case of testing the O2 sensor with a automotive meter then changing the appropiate sensor as theri are two sensors fitted one before the cat and one after but without a tester on it its difficult to say but i would check the after the cat sensor first.

PO170 is a fuel trim malufunction. On a V6 this applies to the rear cylinder head. Lots of possibilities as fu"el trim" refers to the volume air flow sensor, fuel injector, fuel pressure, engine coolant senor, air intake sensor, barometric pressure sensor, oxygen sensor, intake air leaks, or cracks in the exhaust manifold

Try replacing the gas tank cover. Seriously. If that does not work, it could be the clutch sensor.

Oxygen sensor 2000 galant


The first sensor closest to the exhaust manifold is for the air to fuel ratio. The second one if it has one will be further downstream and checks to see if exhaust is plugged.

Is your car running right especially at idle????
