Test NTC-17: Checking Battery Temperature Sensor

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION  . For wiring diagram, see WIRING DIAGRAMS article.
  1. Turn ignition on with engine off. Using scan tool, read temperature of battery temperature sensor. Using thermometer, measure underhood temperature near battery tray. If underhood temperature is within 10 degrees of temperature of battery temperature sensor, go to next step. If underhood temperature is within 10 degrees of temperature of battery temperature sensor, replace battery temperature sensor. Battery temperature sensor is located on battery tray, below battery and contains a 2-pin connector with Black/Light Blue and Pink/Yellow wires. Perform TEST VER-5  .
  2. Turn ignition off. Inspect wiring harness and connectors between battery temperature sensor and Powertrain Control Module (PCM). PCM is located at passenger's side front corner of engine compartment on inner fender panel. Inspect battery temperature sensor connector and PCM connectors for corroded, pushed out, miswired or damaged terminals. Also, check for related Technical Service Bulletins (TSBs). If no problems and no related TSBs exist, go to next step. If any problems exist, repair wiring or connectors as necessary. Perform TEST VER-5  .
  3. Start engine and allow engine to idle. Wiggle wiring harness and connectors between PCM and IAT sensor. If no problems are found, test is complete. If any problems are found while wiggling wiring harness and connectors, repair wiring or connectors as necessary. Perform TEST VER-5  .
