Possible Causes: IAT sensor connector is damaged (it may be open internally) IAT sensor ground circuit is open Page 1 of 17 print

IAT sensor is damaged or has failed PCM has failed Monitor Information: Make: Toyota OBD II Monitor Type: CCM Comprehensive Component Monitor Overview Current EPA and OBD II regulations require that all emission related circuits and components controlled by the Powertrain Control Module (PCM) that could affect emissions be monitored for circuit continuity and out-of-range conditions. The Comprehensive Component Monitor (CCM) consists of four (4) different monitoring strategies: two to monitor the input signals and two to monitor the output signals.note: The CCM is a 2-trip Monitor for emission related faults on these vehicle applications. Input Strategies One input strategy is used to check devices with analog inputs for opens, shorts, or outof-range values. The CCM accomplishes this task by monitoring the A/D converter input signals. Typical analog inputs monitored by the CCM include the ECT, IAT, MAF, TP and Transmission Range sensor signals.a second input strategy is used to check devices with digital and frequency inputs by performing rationality checks. The PCM uses other sensor readings and calculations to determine if a sensor or switch reading is correct under current conditions. Some rationality tests run continuously while others run after a particular device has be activated. Examples of the inputs monitored by the PCM include the CKP, CMP, OSS and VSS signals. Input Signal Test Graphic Output Strategies An Output State Monitor in the PCM checks outputs for open circuits, short-to-ground or short-to-power conditions by observing the control voltage level of the related device while it is operated. During testing, the control voltage of the device should be low with it enabled; and high with it disabled. The output devices monitored by the CCM include the EGR and EVAP solenoids, fuel injectors, Shift Solenoids, TCC, and the HO2S heater control circuits. Output Command Test Graphic Page 2 of 17

Component Monitor Repair Verification An example of how to drive a vehicle to verify a trouble code related to the Comprehensive Component Monitor has been repaired properly on these vehicle applications is shown in the graphic below. Repair Verification Graphic Message Indicator Lamp: Make: Toyota Indicator: MIL Indicator Explanations: MIL In the trouble code details page, if the "Indicator" line has MIL after it, this indicates the MIL is activated when this particular code is set. If the "Indicator" line is blank, this indicates the MIL is not activated when this particular trouble code is set. In this case, it is treated as a Non-MIL type of trouble code! Malfunction Indicator Lamp The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON or the ISO standard engine symbol (a picture of an engine).the MIL has these two functions: To act as a "bulb check" when the ignition key is first turned on for a few seconds To inform the driver that an "emissions related" fault has been detected by the PCM "Bulb Check" Feature Page 3 of 17

Ignition power is supplied to the MIL when the ignition switch is in the RUN or START position. The MIL will remain "on" in the RUN/START mode as a bulb check during the instrument cluster prove-out period of approximately 3-4 seconds, and then it should go out (a normal event when the circuit works correctly). MIL Operation Graphic MIL Remains "ON" The MIL will remain "on" with the engine running under the following conditions: The PCM detects an emission related concern (a trouble code will be set also). The MIL control circuit is shorted to ground between the "bulb" and the PCM. The PCM has an internal malfunction MIL Remains "OFF" During the "Bulb Check" The MIL will remain off during the "bulb check" under these conditions: The bulb is damaged or missing The MIL system power circuit is open between the "bulb" and the PCM The MIL control circuit is open between the "bulb" and the PCM The PCM has an internal malfunction MIL Is Flashing If the MIL is flashing at a steady rate, one of these conditions is present: A severe misfire condition exists. In this case, read the trouble codes with a Scan Tool to determine if a DTC P0300 series code (e.g., P0301, P0302, P0303, P0304, etc.) is stored in the PCM memory. If the MIL blinks erratically, the system power (B+) circuit may have an intermittent open condition, or the MIL control circuit may have an intermittent short to ground condition. Additionally, the PCM may "reset" itself during cranking if the battery voltage is too low. Page 4 of 17

To Turn Off the MIL To turn off the MIL after a repair is completed, use one of the following procedures Drive the vehicle for three (3) consecutive drive cycles without the fault present that caused the original trouble code to set (i.e., the original fault will not reoccur during the drive cycle). Use the PCM Reset command in the Scan Tool Menu (this is the preferred method).
