DTC Detecting Condition
Trouble Area
Difference between actual throttle opening (detected from TP
sensor) and opening calculated by ECM (obtained on the
basis of engine speed and intake manifold pressure) is larger
than specified value.
(2 driving cycle detection logic)
• Air intake system
• TP sensor
• TP sensor circuit
• ECM
• MAF sensor
• Idle air control valve
WARNING:
• When performing a road test, select a place where there is no traffic or possibility of a traffic acci-
dent and very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.
NOTE:
Check to make sure that the following conditions are satisfied when using this DTC CONFIRMATION
PROCEDURE.
• Intake air temp.: –7°C, 19.4°F or higher
• Engine coolant temp.: 70°C, 158°F or higher
• Altitude (barometric pressure): 2500 m, 8200 ft or less (540 mmHg, 72 kPa or more)
