DTC Detecting Condition Trouble Area
• Manifold absolute pressure sensor output voltage is
higher than specified value for specified time continu-
ously.
(1 driving cycle detection logic)
• Manifold absolute pressure sensor circuit
• Manifold absolute pressure sensor
• Manifold absolute pressure sensor vacuum
passage
• ECM
WARNING:
• When performing a road test, select a place where there is no traffic or possibility of a traffic acci-
dent and be 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.
