СИСТЕМА ECD, Diagnostic DTC:P1010

DTC Code DTC Name
P1010 Outside Temperature Sensor Plausibility Check with Other Temperature Sensor when Cold Start

DESCRIPTION

This DTC is output when the value of the ambient temperature sensor in the ECM is determined to be inappropriate when making comparisons with values from other temperature sensors. This comparison is performed once per driving cycle after a cold start.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory
P1010 Outside Temperature Sensor Plausibility Check with Other Temperature Sensor when Cold Start

When ambient temperature sensor value (ECM) determined to be inappropriate after comparison with other temperature sensors for 0.05 seconds.

(3 trip detection logic)

 ECM Does not come on DTC stored

CAUTION / NOTICE / HINT

Note

When replacing the ECM, the ECM needs registration and initialization.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

  2. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON and turn the GTS on.

    3. Clear the DTCs.


      Powertrain > Engine and ECT > Clear DTCs

    4. Turn the ignition switch off and wait for 60 seconds or more [A].

    5. Perform road test [B].

    6. Repeat [A] and [B] for the number of trips detected.

    7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.


      Powertrain > Engine and ECT > Trouble Codes

    8. Confirm that the DTC is not output again.
