Diagnostic Procedure

CAUTION: To prevent damage to scan tool, always turn ignition switch to LOCK position before connecting or disconnecting scan tool.
  1. Using scan tool, check fuel temperature sensor. Connect scan tool to data link connector. Turn ignition on. Set scan tool to the data reading mode for data list item 4A: FUEL TEMPERATURE SENSOR. Data should be approximately the same as the outside temperature when engine is cooled. Turn ignition switch to LOCK position. If sensor is not operating properly, go to next step. If sensor is operating properly, malfunction is intermittent.
  2. Check fuel temperature sensor. Disconnect fuel temperature sensor harness connector. Using a DVOM, measure resistance between fuel temperature sensor terminals No. 1 and 3. Standard value is 0.5-12.0 k/ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace fuel temperature sensor. After replacing sensor, go to step  5 .
  3. Check fuel temperature sensor harness connector and ECM harness connector C-115 (M/T) or PCM harness connector C-118 (A/T) for damage. If connector is in good condition, go to next step. If connector is not in good condition, repair or replace as necessary. After repairs, go to step  5 .
  4. Check for short to ground between fuel sensor harness connector D-10 and ECM harness connector C-115 (M/T) or PCM harness connector C-118 (A/T). If wiring harness is in good condition, replace ECM or PCM. After replacing ECM or PCM, go to next step. If wiring harness is not in good condition, repair as necessary. After repairs, go to next step.
  5. Test the OBD-II drive cycle. Carry out a test drive with the drive cycle pattern. See OTHER MONITOR  under VERIFYING REPAIRS. Check for DTCs. If DTC P0182 is output, repeat diagnosis. If DTC P0182 is not output, inspection is complete.
