Detecting condition
(DTC will set when detecting:)
Output waveforms of HO2S-1 and HO2S-2 are similar.
Monitor signal of EVAP canister purge valve is different
from command signal. (circuit open or shorted to ground)
Circuit voltage of fuel level sensor is less than
specification.
Circuit voltage of fuel level sensor is more than
specification.
Monitor signal of radiator cooling fan relay is different from
command signal.
Monitor signal of A/C condenser cooling fan relay is
different from command signal.
No VSS signal during fuel cut for specified time or longer.
Output voltage of A/C refrigerant pressure sensor is less
than specification.
Output voltage of A/C refrigerant pressure sensor is more
than specification.
Data write error or check sum error.
Data programming error.
Starter signal is low voltage even though engine is started
with vehicle at stop.
Starter signal is high voltage for specified time while
engine is running.
Backup power voltage is out of specification after starting
engine.
Monitor signal of throttle actuator output (duty output) is
inconsistent with throttle actuator control command.
Power supply voltage of throttle actuator control circuit is
lower than specification even if throttle actuator control
relay turned on.
Power supply voltage of throttle actuator control circuit is
higher than specification even if throttle actuator control
relay turned off.
Throttle valve default opening is greater than 8° from
complementary closed position when diagnosing throttle
valve at ignition switch turned OFF.
Difference between actual throttle valve opening angle
and opening angle calculated by ECM is more than
specification.
Output voltage of pedal position sensor (main) is lower
than specification.
Output voltage of pedal position sensor (main) is higher
than specification.
Output voltage of pedal position sensor (sub) is lower
than specification.
Output voltage of pedal position sensor (sub) is higher
than specification.
Difference between the opening angle based on throttle
position sensor (main) and the opening angle based on
throttle position sensor (sub) is more than specification.
