An open or shorted condition detected in the control circuit of the #2 high speed radiator fan control relay. Low power, engine derated, or engine stops. Do you see our code list? Thats the simplest way to pull your code. You may see a cylinder misfire code or fuel injector-specific code with P0171. Fantastic. Engine power will be derated. Oxygen sensor input voltage maintained below normal operating range. Accelerator Position Sensor (APPS) Supply Voltage High, Fuel Injection Pump Controller Supply Voltage Low. RECALLS! I already inspected wire harness, TCM, ECU and some grounds, they all are in good condition with no visibly damage. The model was later discontinued by Jeep in 2012. Low power, engine derated, or engine stops. Was MIL code 37. Intake Manifold Short Runner Solenoid Circuit. Flex fuel sensor input below minimum acceptable voltage. This SBEC III or JTEC DTC indicates that the EATX or Asin controller has an active fault and has illuminated the MIL via a CCD (EATX) or SCI (Aisin) message. Did you know that.
