DIAGNOSTIC TROUBLE CODES
HINT:
•
If a malfunction is detected during the diagnostic trouble code check, refer to the circuit indicated in the
table, and turn to the corresponding page.
•
Your readings may vary from the parameters listed in the table, depending on the instruments used.
(1) Oxygen sensor output is less than 0.45
V for at least 90 secs. when oxygen
sensor is warmed up (racing at 2,000
rpm). –Only for code 25.
*4
(2) When the air–fuel compensation value
fluctuates more than 20% from the
ECM set range within 60 secs. period
while driving at 15 km/h (9 mph) or
more at coolant temp. of 70
°
C (158
°
F )
or above.

(1) Open or short in heater circuit of main oxy–
gen sensor for 500 msec. or more. (HT)
(2) At normal driving speed (below 60 mph and
engine speed is above 1,700 rpm),
amplitude of main oxygen sensor signal
(OX 1) is reduced to between 0.35–0.70
V continuously for 60 secs. or more.
*6 (2 trip detection logic) (2)
NE signal is not input to ECM for 300
msec. or more when engine speed is 1,500
rpm or more.
Open or short in intake air temp. sensor
circuit for 500 rnsec. or more. (THA)
