INSPECTION
PROCEDURE
1. INSPECT VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)
|
(a) Measure the resistance according to the value(s) in the table below. Text in Illustration
Standard Resistance:
If the result is not as specified, replace the air cleaner assembly. |
|
(b) Check the vacuum switching valve operation.
|
(1) When vacuum is applied to port E, check that air is sucked into the filter. Text in Illustration
If the result is not as specified, replace the air cleaner assembly. |
|
|
(2) Apply battery voltage across the terminals. When vacuum is applied to port F, check that air is sucked into port E. Text in Illustration
If the result is not as specified, replace the air cleaner assembly. |

RemovalIntake Air Temperature Sensor Gradient Too High (P0111)
DESCRIPTION
The intake air temperature sensor, mounted on the mass air flow meter,
monitors the intake air temperature. The intake air temperature sensor has
a built-in thermistor with a resistance that varies according to the temperature

Cold Start Idle Air Control System Performance (P050A)
MONITOR DESCRIPTION
This monitor will run when the engine is started at an engine coolant temperature
of -10 to 50°C (14 to 122°F). The DTC is stored after the engine idles for 13
seconds (2 trip detection logic).
The DTC is designed to monitor the idl ...
