DTC P011B Engine Coolant Temperature / Intake Air Temperature Correlation
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 20C (68F), the ECM will judge this as a malfunction and will set this DTC

INSPECTION PROCEDURE
1 CHECK ANY OTHER DTCS OUTPUT (IN ADDITION P011B)
Result
HINT: If any DTCs other than P011B are output, troubleshoot those DTCs first
2 READ VALUE OF INTELLIGENT TESTER (INTAKE AIR TEMPERATURE)
HINT: It is necessary leave the vehicle for 7 hours or more to allow conditions similar to the DTC detection conditions.
OK: The intake air temperature and the outside air temperature are within 10C (50F) 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)
OK: The coolant temperature and the outside air temperature are within 10C (50F) 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.

INSPECTION PROCEDURE
1 CHECK CABIN
Check that conditions in the cabin are not likely to cause
condensation.
HINT:
This problem occurs when the cabin is humid and the
temperature rapidly changes. This condition may
produce condensation, resulting in a short circuit.
OK:
Condensation ...
Installation
1. INSTALL STEERING PAD
Support the steering pad with one hand as shown in
the illustration.
Connect the 2 connectors to the steering pad.

INSPECTION
1. INSPECT WINDOW DEFOGGER SWITCH
Check the defogger switch illuminates.
Standard
If the result is not as specified, replace the switch
assembly or bulb.
Check the defogger timer.
Connect the positive (+) lead from the battery
to terminal 2 and ...
