Engine code33 or 32 service engine


Hello, Your Code 32 means that an O2 circuit is reading high. Its position is Bank1 spot1. The Code 33 would go to a vehicle with a turbo or supercharger. Code 33 concerns the Turbo bypass circuit, if so equipped.

You can continue to get free scans at Autozone, Advance or Oreilys. The O2 sensor should be replaced or check the wiring for a grounded wire to the O2 sensor.

    I have a 1997 dodge stratus es with the 2.5 v6 and my check engine light came on. i checked the codes and came up with codes 12, 32 and 17. What are these codes


    Code 12 = Number of Key-Ons since last Fault (code) or since Fault(s) were erased.
    Code 32 = a) EGR Solenoid Circuit or b)EGR System Failure. For a): An Open or Shorted Condtion has been detected in the EGR Solenoid Circuit. This is usually for some California Vehicles.
    For b): Required Air/Fuel Ratio was not detected during Diagnostic Test. Again for some California Vehicles.
    In either case: Replace the EGR
    Code 17 = Engine Runs Cold for too long. Engine Coolant Temperature remains Below Normal Operating Temp's during Vehicle travel. This is a Thermostat problem. Replace it.
    Let me know if this helped, or if you have additional questions or information. Feel free to contact me at FixYa.com!

    My check engine light comes on after driving a while it first had code 32 and then the car (92 firebird, 305) does not start now and checked the codes and they are code 32,53,54. My engine does not role...


    code 32 - egr system error.
    code 53- vehicle anti theft system fault
    code 54 - fuel pump voltage low
    suggest that your vehicle anti theft system is causing the no turn over condition

    Hard Start with trouble code 32


    You should have your battery checked, it may be getting old and doesn;t have as much cold cranking power, I don;t think code 32 has anything to do with the slow cranking when cold.


    Trouble Code 32 indicates that the Exhaust Gas Recirculation (EGR) valve diaphragm is not where the ECM expects it to be. The ECM controls the diaphragm with a Pulse-Width Modulated (PWM) waveform. The EGR has a vacuum bleed solenoid that adjusts the vacuum applied to the EGR valve based on this pulse width. If there is sufficient vacuum at the EGR valve, a switch closes to send a signal back to the ECM. The absence of this signal is the bases for code 32.
    The conditions for setting this code are:
    • no vacuum to EGR (switch open), and
    • Code 33 or 34 (MAF error) is not present, and
    • engine running and LV8 is less than 100, and
    • coolant temperature is > 118 deg F (48 deg C), and
    • the EGR solenoid duty cycle is < 65%, and
    • the above conditions are met for more than 25 seconds


    Typical causes for this code include:
    1) Faulty EGR valve-to-ECM connection
    2) Plugged EGR passages and/or sticking EGR valve
    3) Defective EGR valve
    4) Defective ECM
