DTC P0113: INTAKE AIR TEMPERATURE SENSOR VOLTAGE HIGH Jeep Cherokee II рестайлинг

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION . For circuit identification and wiring diagram, see CHEROKEE wiring diagram in WIRING DIAGRAMS article.

Note. DTC P0113: INTAKE AIR TEMPERATURE SENSOR VOLTAGE HIGH is monitored with ignition on and battery voltage more than 10.4 volts. DTC may be stored in Powertrain Control Module (PCM) when PCM senses Intake Air Temperature (IAT) sensor voltage is more than 4.9 volts. Possible causes are: defective IAT sensor, defective PCM, defective connectors or defective wiring.

1. Turn ignition on, with engine off. Using scan tool, read IAT sensor voltage. If voltage is more than 4.5 volts, go to next step. If voltage is 4.5 volts or less, go to step 7).
2. Turn ignition off. Disconnect IAT sensor connector. (Схема №23) Clean and/or repair connector as necessary. Connect a jumper wire between IAT sensor connector, signal circuit (Black/Red wire) and sensor ground circuit (Brown/Yellow wire). Turn ignition on, with engine off. Using scan tool, read IAT sensor voltage. If voltage is less than one volt, replace IAT sensor. Perform TEST VER-5A. If voltage is one volt or more, go to next step.
3. Turn ignition off. Ensure IAT sensor connector is still disconnected. Turn ignition on, with engine off. Using a voltmeter, check voltage on IAT sensor connector, signal circuit (Black/Red wire). If voltage is more than 6 volts, repair signal circuit for short to voltage. Perform TEST VER-5A. If voltage is 6 volts or less, go to next step.
4. Turn ignition off. Ensure IAT connector is still disconnected. Connect a jumper wire between ground and IAT sensor connector, sensor ground circuit (Brown/Yellow wire). Turn ignition on, with engine off. Using scan tool, read IAT sensor voltage. If voltage is less than one volt, repair open sensor ground circuit. Perform TEST VER-5A. If voltage is one volt or more, go to next step.
5. Ensure ignition is off. Ensure IAT sensor connector is still disconnected. Disconnect PCM connectors. PCM is located in engine compartment. See PCM LOCATION table under SYSTEM DIAGNOSTICS. Clean and/or repair connectors as necessary. Using an ohmmeter, check resistance of IAT sensor ground circuit (Brown/Yellow wire) between IAT sensor and PCM. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open sensor ground circuit. Perform TEST VER-5A.
6. At this time, PCM is assumed to be defective. Replace PCM. Perform TEST VER-5A.
7. Turn ignition on, with engine off. Wiggle IAT sensor connector and wiring harness while monitoring IAT sensor voltage. (Схема №23) If voltage changes while wiggling connector and wiring harness, repair connector or wiring harness where wiggling caused voltage to change. Perform TEST VER-5A. If voltage does not change, go to next step.
8. Turn ignition off. Visually inspect related connectors and wiring harness for damage. Repair connectors and wiring harness as necessary. Perform TEST VER-5A. If connectors and wiring harness are okay, test is complete.
