P2627 O2 Sensor Pumping Current Trim Circuit Low Bank 1, Sensor 1 A resistor is installed in the universal heated oxygen sensor (HO2S) connector for part to part variance. The powertrain control module (PCM) determines the value of this resistor by taking multiple measurements of the resistor during each key on event. The PCM uses this value in order to compensate for the variance in the pumping current signal. The test fails if the PCM determines the resistance value is too high. See HEATED OXYGEN SENSOR (HO2S) .
P2630 O2 Sensor Pumping Current Trim Circuit Low Bank 2, Sensor 1 A resistor is installed in the universal heated oxygen sensor (HO2S) connector for part to part variance. The powertrain control module (PCM) determines the value of this resistor by taking multiple measurements of the resistor during each key on event. The PCM uses this value in order to compensate for the variance in the pumping current signal. The test fails if the PCM determines the resistance value is too high. See HEATED OXYGEN SENSOR (HO2S) .
Pxxxx - - For Pxxxx DTCs not listed in this chart, refer to the customer's symptom to determine the applicable procedure for diagnosis.
U0109 Lost Communication With Fuel Pump Control Module The PCM monitors the fuel pump monitor (FPM) circuit for the presence of a duty cycled signal. If the FPM circuit is fixed at a low or high-voltage, the PCM begins to increment a counter. The test fails when the PCM is still not detecting a duty cycled signal on the FPM circuit after a calibrated amount of time. See FUEL PUMP (FP) PRIMARY OR SECONDARY CIRCUIT .
U0121 Lost Communication With Anti-lock Brake System (ABS) Control Module The PCM continuously monitors the controller area network (CAN) for messages from the ABS. This DTC sets when the PCM fails to receive the ABS message within the defined amount of time. See COMMUNICATIONS NETWORK TROUBLESHOOTING .
U0155 Lost Communication With Instrument Panel Cluster Control Module Missing message concerns are logged by a module upon failure to receive a message from another module within a defined retry period. See COMMUNICATIONS NETWORK TROUBLESHOOTING .
U0300 Internal Control Module Software Incompatibility This DTC indicates there are incompatible software levels within the PCM that control the electronic throttle control (ETC) system. The ETC system uses multiple microprocessors within the PCM, each having its own software level and function. The microprocessors must have the correct level of software in order to communicate and function together. See POWERTRAIN CONTROL MODULE (PCM) MALFUNCTION .
U210B Lost Communication Between Fuel Pump Control Module and Restraints Control Module The fuel pump control module monitors the duty cycle and frequency of the signal it receives from the restraints control module (RCM), The fuel pump control module determines if the signal on the event notification signal (ENS) circuit from the RCM is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module sends a 40% duty cycle signal on the fuel pump monitor (FPM) circuit to report the concern to the PCM. The test fails when the fuel pump control module is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time.
