Toyota Corolla Cross: Inspection
INSPECTION
PROCEDURE
1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY
(a) Perform a visual check for any foreign matter on the temperature sensor (thermistor) of the mass air flow meter sub-assembly shown in the illustration.
OK: There is no foreign matter. If the result is not as specified, replace the mass air flow meter sub-assembly. |
|
(b) Clean the intake air temperature sensor (thermistor).
NOTICE:
- Do not contact the mass air flow meter sub-assembly with the nozzle of the air blow gun.
- Do not insert the nozzle of the air blow gun into the intake air temperature sensor (thermistor) area.

*b | 10 mm (0.394 in.) |
*c | Intake Air Temperature Sensor (Thermistor) |
(1) Using an air blow gun, clean the intake air temperature sensor (thermistor) area of the mass air flow meter sub-assembly by applying approximately 10 intermittent bursts of air to the intake air temperature sensor (thermistor) area at a pressure of approximately 392 to 981 kPa (4.0 to 10.0 kgf/cm2, 57 to 142 psi).
HINT: After performing cleaning, read the value of Data List item "MAF" using the GTS and if the value is not as specified, replace the mass air flow meter sub-assembly. |

*a | Air Blow Duration |
*b | 3 to 6 Seconds |
*c | 1 Second |
*d | Air Blowing |
*e | Air Stopped | | |
(c) Check the intake air temperature sensor (thermistor) resistance.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
4 (THA) - 2 (E2G) |
Always | 0.47 to 19.3 kΩ |
If the result is not as specified, replace the mass air flow meter sub-assembly. |

If the PKSB (Parking Support Brake) determines that a collision with
a detected object is possible, the engine output will be restricted to
restrain any increase in the vehicle speed. (Engine output restriction

NOTICE:
Since the brake lines are critical safety related parts, be sure to
disassemble and inspect the components if a brake fluid leak is found. If
any abnormalities are found, replace the component with a new one.
