HOME Test 5.20 (Part 1 of 2) IAT SENSOR: DTC P0112, P0113 1 Connect Breakout Box to connector [78B] leaving ECM disconnected. With engine at room temperature (60-90° F or 16-32° C), use a DVOM to measure resistance across terminals 7 and 26 on Breakout Box. If engine is warm, refer to Table 5-29. Resistance between 2.0k ohms and 5.0k ohms at room temperature YES NO Connect ECM to Breakout Box. Perform 5.8 WIGGLE TEST to check for intermittents. Intermittents present STOP Go to Test 5.20 (Part 2 of 2). YES NO While wiggling harness, perform steps marked by BOLD ASTER- ISKS under Test 5.20 (Part 2 of 2). Repair as necessary. Disconnect IAT sensor connector [89]. Turn ignition ON. Using a DVOM, measure the voltage between ECM terminal 7 (positive) and terminal 26 (negative) on Breakout Box. Voltage approximately 5 volts YES NO. Less than 4.7 volts. NO. Greater than 5.3 volts. Replace IAT sensor, clear codes and road test. Did check engine lamp illuminate and set DTC P0112 or P0113 1 With IAT sensor disconnected, disconnect ECM from breakout box. Measure resistance between Breakout Box terminal 7 and terminals 10 or 28. Resistance less than 1 megohm 1 Unplug ECM leaving Breakout Box connected at vehicle harness. Measure voltage between Breakout Box terminal 7 and terminals 10 or 28. Voltage 0 volts YES NO YES NO YES NO Install original IAT sensor, replace ECM, perform password learning and road test. System OK. Repair short to ground on Lt GN/Y wire. Replace ECM. Reprogram and learn password. Replace ECM. Reprogram and learn password. Examine IAT signal wire (Lt GN/Y) for short to voltage and repair. Clear codes using speedometer self diagnostics. See 5.6 SPEEDOMETER SELF DIAGNOSTICS. Confirm proper operation with no check engine lamp. At some point in the flow chart you may be instructed to jump directly to a the box with the bold asterisk. Disregard the asterisk (but not the instruction box) if your normal progression through the chart brings you to this location. 2004 Touring: Engine Management (EFI) 5-75
