DESCRIPTION
Refer to DTC P011011.

HINT:
When DTC P011015 is stored, the ECM enters fail-safe mode. During fail-safe mode, the intake air temperature is estimated to be 20°C (68°F) by the ECM. Fail-safe mode continues until a pass condition is detected, and the ignition switch is then turned off.
DTC No. | Detection Item |
DTC Detection Condition | Trouble Area |
MIL | Note |
---|---|---|---|---|---|
P011015 | Intake Air Temperature Sensor 1 Bank 1 Circuit Short to Battery or Open |
The intake air temperature sensor output voltage is higher than 4.91 V for 0.5 seconds or more (1 trip detection logic). |

HINT:
When a DTC is output, check the Data List item "Intake Air Temperature" using the GTS.

DTC No. | Intake Air Temperature |
Malfunction |
---|---|---|
P011015 |
Higher than 123°C (253°F) |
|
If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
MONITOR DESCRIPTION
The ECM monitors the sensor voltage and uses this value to calculate the intake air temperature. When the intake air temperature sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the intake air temperature sensor circuit, illuminates the MIL and stores a DTC.
Example:
If the intake air temperature sensor output voltage is higher than 3.76 V for 0.5 seconds or more, the ECM will illuminates the MIL and store this DTC.

HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. |
CHECK HARNESS AND CONNECTOR |
*a | Front view of wire harness connector (to Mass Air Flow Meter Sub-assembly) |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the mass air flow meter sub-assembly connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition |
Specified Condition |
---|---|---|
C26-4 (VCC) - C26-2 (E2G) |
Ignition switch ON | 4.8 to 5.2 V |
C26-1 (THA) - C26-2 (E2G) |
Ignition switch ON | 4.8 to 5.2 V |
(d) Turn the ignition switch off and wait for at least 30 seconds.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
---|---|---|
C26-2 (E2G) - Body ground |
Ignition switch off | Below 1 Ω |
C26-4 (VCC) - C26-1 (THA) |
Ignition switch off | 2.565 to 2.835 kΩ |
HINT:
Perform "Inspection After Repair" after replacing the mass air flow meter sub-assembly.
