P0108 BARO sensor circuit high input
x
The PCM monitors the input voltage from the BARO sensor when the engine is running. If the input voltage is
more than 4.02 V , the PCM determines that the BARO sensor circuit input voltage is high.
P0130 A/F sensor circuit problem
x
The PCM monitors the A/F sensor impedance when under the A/F sensor heater control. If the impedance is
more than 500 ohms
, the PCM determines that there is a A/F sensor circuit problem.
P0131 A/F sensor circuit low input
x
Detect any of the following condition:
—
The input voltage to the A/F sensor positive terminal is 1.128 V or less .
—
The input voltage to the A/F sensor negative terminal is
0.044 V or less
.
—
The electric potential difference between the A/F sensor positive and negative terminals is 0 V or less .
P0132 A/F sensor circuit high input
x
Detect any of the following condition:
—
The input voltage to the A/F sensor positive terminal is
3.589 V or more
.
—
The input voltage to the A/F sensor negative terminal is 3.541 V or more .
P0133 A/F sensor circuit slow response
x
The A/F sensor output signal reacts at a slower timing than expected from the fuel feedback amount.
MONITORING CONDITIONS
—
A/F sensor heater monitor: completed
—
Fuel system loop status: closed loop fuel control
—
Engine speed: 1,500–4,000 rpm
—
LOAD:
21.7–64.7 %
P0134 A/F sensor no activity detected
x
The PCM monitors the A/F sensor element impedance when the following conditions are met. If the A/F sensor
element impedance is 50 ohms or more , the PCM determines that A/F sensor is not activated.
MONITORING CONDITIONS
—
A/F sensor heater, HO2S heater, A/F sensor, HO2S, and TWC Repair Verification Drive Mode
—
Following conditions are met:
x
Time from engine start is above 40 s (ECT when engine start is 20
q
C {68
q
F} ).
P0137 HO2S circuit low input
x
The PCM monitors input voltage from HO2S. If the input voltage from the HO2S is below 0.1 V for 35.2 s the
PCM determines that circuit input is low.
MONITORING CONDITIONS
—
A/F sensor heater, HO2S heater, A/F sensor, HO2S, and TWC Repair Verification Drive Mode
—
Following conditions are met:
x
Engine speed is above 1,500 rpm .
x
Engine coolant temperature is
above 70 q C {158 q F}
.
x
Fuel injector control in HO2S closed loop control.
x
The PCM monitors the input voltage from the HO2S when the following conditions are met. Under the following
monitoring conditions, if the input voltage from the HO2S does not even
exceed 0.1 V
though the short term
fuel trim is controlled, the PCM determines that sensor circuit input is low.
MONITORING CONDITIONS
—
A/F sensor heater, HO2S heater, A/F sensor, HO2S, and TWC Repair Verification Drive Mode
—
Following conditions are met for above 20.8 s :
x
Engine speed is
above 1,500 rpm
.
x
Engine coolant temperature is above 70
q
C {158
q
F} .
P0138 HO2S circuit high input
x
The PCM monitors the input voltage from the HO2S when the engine is running. If the input voltage is more
than 1.2 V
, the PCM determines that the HO2S circuit voltage is high.
P0139 HO2S circuit slow response
x
The PCM monitors the HO2S inversion cycle period and rich-to-lean response time while under the open loop
fuel control (fuel cut off control). If the average response time is more than the specification, the PCM
determines that the HO2S circuit response is slow.
P0327 KS No.1 circuit low input
x
The PCM monitors the input voltage from the KS No.1 when the engine is running. If the input voltage is
less
than 1.2 V , the PCM determines that the KS No.1 circuit input voltage is low.
P0328 KS No.1 circuit high input
x
The PCM monitors the input voltage from the KS No.1 when the engine is running. If the input voltage is more
than 4.0 V
, the PCM determines that the KS No.1 circuit input voltage is high.
P0332 KS No.2 circuit low input
x
The PCM monitors the input voltage from the KS No.2 when the engine is running. If the input voltage is
less
than 1.2 V , the PCM determines that the KS No.2 circuit input voltage is low.
