66 DFC PROBABLE FAULT FAULT ACTION * CORRECTIVE ACTION FIRST CHECK 221 (22) TPS1RangeLow TPS1 sensor voltage out of range low, normally set if the TPS1 signal has shorted to ground, circuit has opened or sensor has failed TurnOnMil Check throttle connector connection and TPS1 sensor for an open circuit or short to GND SECM Pin B23 (signal) to ETC Pin 6 SECM Pin B1 (sensor GND) to ETC Pin 2 SECM (system GND) Pin A16, B17 222 TPS2RangeLow TPS2 sensor voltage out of range low, normally set if the TPS2 signal has shorted to ground, circuit has opened or sensor has failed TurnOnMil Check throttle connector connection and TPS2 sensor for an open circuit or short to GND SECM Pin B4 (signal) to ETC Pin 5 SECM Pin B1 (sensor GND) to ETC Pin 2 SECM (system GND) Pin A16, B17 231 (23) TPS1RangeHigh TPS1 sensor voltage out of range high, normally set if the TPS1 signal has shorted to power or the ground for the sensor has opened TurnOnMil Check throttle connector and TPS1 sensor wiring for a shorted circuit SECM Pin B23 (signal) to ETC Pin 6 SECM Pin B1 (sensor GND) to ETC Pin 2 232 TPS2RangeHigh TPS2 sensor voltage out of range high, normally set if the TPS2 signal has shorted to power or the ground for the sensor has opened TurnOnMil Check throttle connector and TPS1 sensor wiring for a shorted circuit SECM Pin B4 (signal) to ETC Pin 5 SECM pin B1 (sensor GND) to ETC Pin 2 241 (24) TPS1AdaptLoMin Learned closed throttle end of TPS1 sensor range lower than expected None Check the throttle connector and pins for corrosion.
To check the TPS disconnect the throttle connector and measure the resistance from: TPS Pin 2 (GND) to Pin 6 (TPS1 SIGNAL) (0.7 Ω ± 30%) TPS Pin 3 (PWR) to Pin 6 (TPS1 SIGNAL) (1.4 Ω ± 30%) 242 TPS2AdaptLoMin Learned closed throttle end of TPS2 sensor range lower than expected None Check the throttle connector and pins for corrosion. To check the TPS disconnect the throttle connector and measure the resistance from:
TPS Pin 2 (GND) to Pin 5 (TPS2 SIGNAL) (1.3K Ω ± 30%) TPS PIN 3 (PWR) to PIN 5 (TPS2 SIGNAL) (0.6K Ω ± 30%) 251 (25) TPS1AdaptHiMax Learned WOT end of TPS1 sensor range higher than expected None N/A 252 TPS2AdaptHiMax Learned WOT end of TPS2 sensor range higher than expected None N/A 271 TPS1AdaptHiMin Learned WOT end of TPS1 sensor range lower than expected None N/A
