DTC DETECTION LOGIC AND CONDITIONS [13B-MSP]
id0102g1100300
x
The detection condition of the following DTC has been changed from 2008MY.
B1342 PCM malfunction
x
Malfunction in the PCM internal circuit.
P0030 A/F sensor heater control circuit problem
x
The PCM monitors the A/F sensor impedance when under the A/F sensor heater control for 190 s . If the
impedance is more than
44 ohms
while PCM turns A/F sensor heater on, the PCM determines that there is a
A/F sensor heater control circuit problem.
P0031 A/F sensor heater control circuit low input
x
The input voltage to the A/F sensor heater drive terminal in the PCM is at the set value or less for 1 s or more
even though the A/F sensor heater is duty-controlled at
under 90 %
by the PCM.
P0032 A/F sensor heater control circuit high input
x
The input voltage to the A/F sensor heater drive terminal in the PCM is at the set value or more for
1 s or more
even though the A/F sensor heater is duty-controlled at 10 % or more by the PCM.
P0037 HO2S heater control circuit low input
x
The input voltage to the HO2S heater drive terminal in the PCM is at the set value or less for 0.5 s or more
even though the HO2S heater is duty-controlled at
under 90 %
by the PCM.
P0038 HO2S heater control circuit high input
x
The input voltage to the HO2S heater drive terminal in the PCM is at the set value or more for
0.5 s or more
even though the HO2S heater is duty-controlled at 10% or more by the PCM.
P0103 MAF sensor circuit high input
x
The PCM monitors the input voltage from the MAF sensor when the engine is running. If the input voltage is
more than 5.0 V , the PCM determines that the MAF sensor circuit input voltage is high.
P0107 BARO sensor circuit low input
x
The PCM monitors the input voltage from the BARO sensor when the engine is running. If the input voltage is
less than 2.09 V
, the PCM determines that the BARO sensor circuit input voltage is low.
