It also refers to heated oxygen sensor (HO2S) 3 bank 1--circuit malfunction===causes --wiring---HO2S--ECM

fix the o2 sensor and the purge valve and you may be on the way to fixing the faults.

    Your car only has one bank, so this code applies for the entire engine. I'll provide a link that gives a good breakdown of what P0170 means, possible causes, and possible corrections.

    Are you sure it is a trans code. Everything that I have found states that P0170 is a fuel trim problem?P0170 Fuel Trim Malfunction (Bank 1)

    The code P0170 means that the air-fuel mixture coming in to the engine is too lean, or too rich. Usually it's the lean condition that causes this code. The code P0173 means the same, only for the Bank 2. Some car manufacturers list the description for the code P0170 as self adaptation out of limits.
    The code P0170 could be caused by a number of reasons, such as vacuum leaks, bad PCV valve, or other parts of crankcase ventilation system, low fuel pressure, bad oxygen sensor, bad MAF sensor or even a bad EGR vlave.

    1998 mazda mpv code p0170 erase code car runs fine but when i stop for a few minutes it is hard to start and runs rough the engine light comes back on and the code will read p0170 again


    This code indicates a fuel ratio problem. I would start by inspecting all the vacuum lines, including the pcv hose and power brake hose. Carefully inspect the air intake hose. This is the large hose between the throttle body and the airflow meter. If this hose is cracked or loose the computer will not sense how much air is being drawn into the engine and it will be hard to start.
