Hint
: hand–held tester only: narrowing down the trouble area is possible by performing ”a/f control” active test (heated oxygen sensor or other trouble areas can be distinguished). Perform active test using hand–held tester (a/f control).
Hint
: ”a/f control” is the active test which changes the injection volume to –12.5 % Or +25 %.
Result: heated oxygen sensor reacts in accordance with increase and decrease of injection volume +25 % rich output: more than 0.5 V, –12.5 % Lean output: less than 0.4 V
Notice
: there is a delay of few seconds in the sensor 1 (front sensor) output, and there is about 20 seconds delay at maximum in the sensor 2 (rear sensor)
The following of a/f control procedure enables the technician to check and graph the voltage outputs of both the heated oxygen sensors.
For displaying the graph indication, enter ”active test / a/f control / user data”, then select ”o2s b1s1 and o2s b1s2” by pressing ”yes” button and push ”enter” button before pressing ”f4” button.
Notice
: if the vehicle is short of fuel, the air–fuel ratio becomes lean and dtc p0133 will be recorded, and the mil then comes on. Hint
:
Check for conditions that would cause the engine to run rich.
Check for conditions that would cause the engine to run lean.
1 Check other dtc output(in addition to dtc p0133)
Result
:
Hint
: if any other codes besides p0133 are output, perform the troubleshooting for those dtcs first.
2 Read value of hand–held tester or obd ii scan tool(heated oxygen sensor during idling)
Heated oxygen sensor output voltage: alternates between less than 0.35 V and more than 0.45 V, and period of ”t” must exist less than 0.6 Sec. (See the following table).
3 Inspect heated oxygen sensor(heater resistance)
Standard:
4 Inspect efi relay
Standard:
5 Check harness and connector(heated oxygen sensor – ecm)
Standard (check for open):
Standard (check for short):
6 Check air induction system
7 Check fuel pressure
8 Inspect fuel injector assy(injection and volume)
Replace heated oxygen sensor
9 Perform confirmation driving pattern
Hint
: clear all dtcs prior to performing the confirmation driving pattern.
10 Read output dtc(dtc p0133 is output again)
Result:
Replace heated oxygen sensor
Front wheel alignment
Adjustment
1. Inspect tire
2. Measure vehicle height
Vehicle height:
Measuring points:
a: ground clearance of front wheel center
b: ground clearance of lower suspension arm front
bolt center
c: ground clearance of axle beam set bolt center
d: ground clearance of rear wheel center

On–vehicle inspection
1. Inspect wireless door lock control functions
Hint:
the switch described in this text is a switch for transmitting
signals (lock switch, unlock switch
and panic switch) which is built into the door control transmitter.
All the functions listed below must be checked in the remote contro ...

Trouble area
P0125
If the engine coolant temperature (ect) was less than –6.6 °C
(20 °F) when starting the engine, and 20 minutes after the engine
start, the ect sensor still indicates below 20 °C (68 °F)
