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).
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.
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 p0134)
Result:
Hint
: if any other codes besides p0134 are output, perform the troubleshooting for those dtcs first.
2 Read value of hand–held tester or obd ii scan tool(output voltage of heated oxygen sensor)
Hint
: quickly accelerate the engine to 4,000 rpm 3 times by using the accelerator pedal.
Standard: heated oxygen sensor outputs a rich signal (0.45 V or more) at least once.
3 Check connection of pcv hose
4 Inspect heated oxygen sensor(heater resistance)
Standard:
5 Inspect efi relay
Standard:
6 Check harness and connector(heated oxygen sensor – ecm)
Standard (check for open):
Standard (check for short):
7 Check whether misfire is occurred or not by monitoring dtc and data list
8 Check air induction system
9 Check fuel pressure
10 Inspect fuel injector assy(injection and volume)
11 Check for exhaust gas leaks
Replace heated oxygen sensor
12 Perform confirmation driving pattern
Hint
: clear all dtcs prior to performing the confirmation pattern.
13 Read output dtc(dtc p0134 is output again)
Result:
14 Confirm if vehicle has run out of fuel in past
Dtc is caused by running out of fuel

Inspection procedure
1 Inspect radio receiver assy(+b, acc, gnd)
Check that the continuity between terminals at each
condition, as shown in the chart.
Standard:
Check that the voltage between terminals at each condition,
as shown in the chart.
