DESCRIPTION
The ECM calculates the difference between the readings of the coolant temperature sensor and intake air temperature sensor. If the difference is greater than 20°C (68°F), the ECM will judge this as a malfunction and will set this DTC.

INSPECTION PROCEDURE
1 CHECK ANY OTHER DTCS OUTPUT (IN ADDITION P011B)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester on.
(d) Enter the following menus: DIAGNOSIS / ENHANCED OBD ll / DTC INFO / CURRENT CODES.
(e) Read the DTCs.
Result
HINT:
If any DTCs other than P011B are output, troubleshoot those DTCs first.
2 READ VALUE OF INTELLIGENT TESTER (INTAKE AIR TEMPERATURE)
(a) Leave the vehicle for 7 hours or more.
HINT:
It is necessary leave the vehicle for 7 hours or more to allow conditions similar to the DTC detection conditions.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
(d) Turn the tester ON.
(e) Enter the following menus: DIAGNOSIS / ENHANCED OBD ll / DATA LIST / PRIMARY / INTAKE AIR.
(f) Read the value displayed on the tester.
OK: The intake air temperature and the outside air temperature are within 10°C (50°F) of each other.
HINT:
Temperature readings on the vehicle's outside temperature gauge (if equipped) are not suitable for comparing to the IAT reading. The outside temperature gauge has a significant delay built in to prevent temperature swings from being displayed on its display.
Use an accurate thermometer to determine the outside air temperature.
3 READ VALUE OF INTELLIGENT TESTER (COOLANT TEMPERATURE)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester ON.
(d) Enter the following menus: DIAGNOSIS / ENHANCED OBD ll / DATA LIST / PRIMARY / COOLANT TEMP.
OK: The coolant temperature and the outside air temperature are within 10°C (50°F) of each other.
HINT:
If the result is not as specified, check that there are heat sources such as a block heater in the engine compartment.

When troubleshooting a vehicle with the diagnosis
system, the only difference from the usual
troubleshooting procedure is connecting the intelligent
tester to the vehicle and reading various data output from
the vehicle's clearance warning ECU.
