The secondary HO2S detects the oxygen content in the
exhaust gas downstream of the three way catalytic
converter (TWC), and sends signals to the ECM/PCM
which varies the duration of fuel injection accordingly.
To stabilize its output, the sensor has an internal heater.
The ECM/PCM compares the HO2S output with the A/F
sensor output to determine catalyst efficiency. The
secondary HO2S is on the TWC. The throttle is electronically controlled by the electronic
throttle control system. Refer to the system diagram to
see a functional layout of the system.
Idle control: When the engine is idling, the ECM/PCM
controls the throttle actuator to maintain the proper idle
speed according to engine loads.
Acceleration control: When the accelerator pedal is
pressed, the ECM/PCM opens the throttle valve,
depending on the accelerator pedal position (APP)
sensor signal.
Cruise control: The ECM/PCM controls the throttle
actuator to maintain the set speed when the cruise
control is operating. The throttle actuator takes the
place of the cruise control actuator.
As the accelerator pedal position changes, the sensor
varies the signal voltage to the ECM/PCM.

Procedure
11-70Fuel and Emissions Systems
How to Set Readiness Codes (cont’d)
NOTE: All readiness codes are cleared when the battery
is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
 Battery voltage is more than 10.5 V.
 Engine at idle.
 ECT SENSOR 1 and ECT SENSOR 2 between 80 °C (176 °F) and 100 °C (212 °F).
 MAP SENSOR less than 46.6 kPa (350 mmHg, 14 in.Hg).
 Vehicle speed (VSS) 0 km/h (0 mph).
 IAT SENSOR between 0 °C (32 °F) and 100 °C (212 °F).
1. Connect the HDS to the DLC.
2. Start the engine.
3. Select EVAP TEST in the INSPECTION MENU with the HDS, then select the FUNCTION TEST in the
EVAP TEST MENU.
 If the result is normal, readiness is complete.
 If the result is not normal, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, one or more of the enable criteria were probably not
met; repeat the procedure. NOTE:
 Do not turn the ignition switch to LOCK (0) or ACC (I) during the procedure.
 All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
ECT SENSOR 1 at 60 °C (140 °F) or more. 1. Start the engine.
2. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. During the
drive, decelerate (with the throttle fully closed) for
5 seconds. After about 5.6 km (3.5 miles), the
readiness code should switch from incomplete to
complete.
3. Check the readiness codes screen for the air fuel ratio (A/F) sensor in the DTCs MENU with the HDS.
 If the screen shows complete, readiness is complete.
 If the screen shows not complete, go to the next step.
4. Check for a Temporary DTC. If there is no DTC, the enable criteria was probably not met. Select the
DATA LIST MENU. Check the ECT SENSOR 1 in the
ALL DATA LIST with the HDS. If the ECT SENSOR 1
is less than 60 °C (140 °F), run the engine until it is
more than 60 °C (140 °F), then repeat the procedure.

NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
 If some of the DTCs listed below are stored at the same time as DTC P0420, troubleshoot them first,
then recheck for DTC P0420.
P0137, P0138: Sec ondary HO2S (Sensor 2)
P0141: Secondary HO2S (Sensor 2) heater
 Poor quality fuel may cause this DTC.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
4. Test-drive under these conditions:  Engine coolant temperature (ECT SENSOR 1)above70°C(158°F)
 A/TinD,M/Tin5th
 Vehicle speed between 72 120 km/h (45 75 mph) for 5 minutes or more with cruise

 K20Z2 engine: Maintain the vehicle speed at 88 km/h (55 mph) for 5 minutes or more with
cruise control set
 K20Z3 engine: Maintain the vehicle speed at 88 km/h (55 mph) for 30 seconds or more
5. Monitor the OBD STATUS for DTC P0420 in the DTCs MENU with the HDS.
Go to step 6.
If the screen indicates OUT OF CONDITION,
go to step 4 and recheck. If the screen indicates
PASSED, intermittent failure, the system is OK at
this time. If the screen indicates FAILED, go to step
8.
6. Continue test driving until a result comes on. 7. Monitor the OBD STATUS for DTC P0420 in the
DTCs MENU with the HDS.
Go to step 8.
If the screen indicates PASSED, intermittent
failure, the system is OK at this time. If the screen
indicates EXECUTING, keep driving until a result
comes on. If the screen indicates OUT OF
CONDITION, go to step 4 and recheck.
8. Turn the ignition switch to LOCK (0).
9. Replace the TWC (see page 11-355).
10. Turn the ignition switch to ON (II).
11. Reset the ECM/PCM with the HDS.
12. Do the ECM/PCM idle learn procedure (see page 11-310).
13. Start the engine. Hold the engine speed at 3,000 rpm without load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
14. Test-drive for about 10 minutes, varying the vehicle speed.
15. Check the CATA MONITOR CONDITION in the DATA LIST with the HDS.
Go to step 16.
Go to step 13 and recheck.

NOTE:  For a cruise control problem, check the clutch pedal position switch (see page 4-50).
 For an engine cranking problem, check the clutch interlock switch (see page 4-8).
 The clutch is self-adjusting to compensate for wear.
 If there is no clearance between the master cylinder piston and the pushrod, the release bearing will be
held against the diaphragm spring, which can result
in clutch slippage or other clutch problems.
1. Lift up the carpet (A). At the insulator cutout, measure pedal height from the right side of the
pedal pad (B). 2. Loosen the clutch pedal position switch locknut (A),
and back off the clutch pedal position switch (B)
until it no longer touches the clutch pedal (C).
3. Loosen the clutch pushrod locknut (D), and turn the pushrod (E) in or out to get the specified height (F)
and stroke (G) at the clutch pedal. If adjusting the
pushrod causes the clutch pedal to contact the
clutch pedal position switch, back off the switch
further.

System Description (cont’d)
Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List.
This should give the HDS time to update the signal on the Data List.
Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not
supported.
Make sure that the most current software is loaded.
