TROUBLE CODE DIAGNOSIS (1.8L DOHC)
CLEARING TROUBLE CODES
Notice : To prevent Engine Control Module (ECM) dam-
age, the key must be OFF when disconnecting or recon-
necting the power to the ECM (for example battery cable,
ECM pigtail connector, ECM fuse, jumper cables, etc.).
When the ECM sets a Diagnostic Trouble Code (DTC), the
Malfunction Indicator Lamp (MIL) lamp will be turned on
only for type A, B and E but a DTC will be stored in the
ECM’s memory for all types of DTC. If the problem is inter-mittent, the MIL will go out after 10 seconds if the fault is
no longer present. The DTC will stay in the ECM’s memory
until cleared by scan tool. Removing battery voltage for 10
seconds will clear some stored DTCs.
DTCs should be cleared after repairs have been com-
pleted. Some diagnostic tables will tell you to clear the
codes before using the chart. This allows the ECM to set
the DTC while going through the chart, which will help to
find the cause of the problem more quickly.

1. The On–Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure re-
cords data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
2. This step will determine if DTC P0107 is the result
of a hard failure or an intermittent condition.
3. Jumpering harness terminals 2 to 1 (signal circuit to
5 volts) will determine if the sensor is malfunction-
ing or if there is a problem with the ECM or wiring.6. The scan tool may not display 5 volts. The Impor-
tant thing is that the ECM recognizes the voltage as
more than 4 volts, indicating that the ECM and the
signal circuit are OK. A test light that illuminates
indicates a short to ground in the signal circuit.
7. A short to ground in the 5 volt reference circuit
could also set additional DTCs.
11. The replacement ECM must be programmed. Refer
to the latest Techline procedure for the ECM repro-
gramming.

Conditions for Clearing the MIL/DTC
S The MIL will turn off after four consecutive ignition
cycles in which the diagnostic runs without a fault.
S A history DTC will clear after 40 consecutive warm–
up cycles without a fault.
S The DTC(s) can be cleared by using the scan tool.
S Disconnecting the ECM battery feed for more than
10 seconds.
Diagnostic Aids
S Normal scan tool voltage varies from 150 mV to
850 mV while in Closed Loop. If DTC P0134 is in-
termittent, refer to ”Intermittents” in this section.
Test Description
Number(s) below refer to the step number(s) on the Diag-
nostic Table.
1. The On–Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure re-cords data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
2. During engine warm–up, the HO2S1 should warm
up, and its voltage output should vary between 150
mv and 850 mv. When the HO2S1 voltage varies,
the engine will go into Closed Loop. This deter-
mines if the HO2S1 1 is operating properly.
4. This will determine if the sensor is malfunctioning or
if the wiring or the ECM is the cause of the DTC
P0134.
6. Use only a high impedance digital voltmeter (DVM)
for this test. The test checks the continuity of the
HO2S1 signal and the ground circuits; if the ground
circuit is open, the ECM voltage on the circuit will
be over 0.6 volts (600 mv).
10. The replacement ECM must be reprogrammed.
Refer to the latest Techline procedure for ECM re-
programming.

Diagnostic Aids
An intermittent may be caused by rubbed–through wire in-
sulation or a wire contacting the exhaust.
Check for the following conditions:
S Exhaust system – Inspect the exhaust system for
leaks. Check the exhaust between the three–way
catalytic converter and the flange for leaks, corro-
sion, or for loose or missing hardware and repair as
necessary.
S Poor connection or damaged harness – Ensure that
the HO2S2 pigtail is not contacting the exhaust.
Check for the following conditions:
S Improper mating
S Broken locks
S Improperly formedS Damaged terminals
S Poor terminal–to–wire connection
S Damaged harness
S Intermittent test – Observe the HO2S2 on the scan
tool while moving related connections and the wir-
ing harness with the ignition ON. If the failure is in-
duced, the HO2S2 display will change. This may
help isolate the location of the malfunction.

2. This step determines if DTC P0137 is the result of
a hard failure or an intermittent condition.
4. Jumping the HO2S2 low circuit, terminal 4 to
ground is necessary to allow the ECM to display
the supplied bias voltage. If the voltage is between
0.35 and 0.55 volt, then the wiring and ECM are
OK.
6. The replacement ECM must be reprogrammed.
Refer to the latest Techline procedure for ECM re-
programming.

S A history DTC will clear after 40 consecutive warm–
up cycles without a fault.
S The DTC(s) can be cleared by using the scan tool.
S Disconnecting the ECM battery feed for more than

Diagnostic Aids
Check for the following conditions:
S Rich exhaust – An overly rich exhaust may load the
catalyst, causing high HO2S2 signal voltages.
S Silicone contamination – A false rich condition may
be caused by silicone contamination of the HO2S2.
This will be indicated by a powdery white deposit on
the sensor.
S Faulty HO2S2 – If HO2S2 is internally shorted, the
HO2S2 voltage displayed on a scan tool will be
over 1 volt. Disconnect the HO2S2 and jumper the
sensor low circuit to engine ground; if the displayed
voltage goes from over 1000 millivolt to around 450
millivolt, replace the HO2S2.S Intermittent test – Observe HO2S2 on the scan tool
while moving related connectors and the wiring har-
ness with the key in the ON position. If the failure is
induced, the HO2S2 display will change. This may
help isolate the location of the malfunction.

5. Disconnecting the HO2S2 and jumpering the sen-
sor signal circuit and the sensor low circuit to

HO2S2 voltage below 100 mv (0.1 v). If the signal
voltage is still high, the ECM is malfunctioning.
