Symptom List: P1515-ACCEL. PEDAL SENSOR PLAUSIBILITY Test Note: All symptoms listed above are diagnosed using the same tests. The title for the tests will be P1515-ACCEL. PEDAL SENSOR When Monitored and Set Condition: P1515-ACCEL. PEDAL SENSOR PLAUSIBILITY When Monitored: With the ignition on. Set Condition: The accelerator pedal position sensor signal is below 0.2 volt (4%) or above 4.5 volts (90%) and the idle switch is not in the correct state. NOTE: The idle switch is P1515-ACCEL. PEDAL SENSOR PWG PLAUS WITH POTENTIOMETER When Monitored: With the ignition on. Set Condition: The accelerator pedal position sensor signal is below 0.20 volts, the idle switch transitions at too high a percentage intermittently or the idle switch is not in the P1515-ACCEL. PEDAL SENSOR SIGNAL HIGH EXCEEDED When Monitored: With the ignition on. Set Condition: The accelerator pedal position sensor signal voltage is above 4.5 volts. NOTE: This code sets the ECM to Limp-in Mode, which includes a fixed engine speed of P1515-ACCEL. PEDAL SENSOR SUPPLY HIGH EXCEEDED When Monitored: With the ignition on. Set Condition: The ECM detects voltage on the accelerator pedal position sensor 5-volt supply circuit above 5.2 volts. P1515-ACCEL. PEDAL SENSOR SUPPLY LOW EXCEEDED When Monitored: With the ignition on. Set Condition: The ECM detects voltage the accelerator pedal position sensor 5-volt supply circuit below 4.75 volts. 160 DRIVEABILITY - DIESEL |
