DTC P0420: Catalytic System Efficiency
Below Threshold
NOTE: lf some of the DTCS listed below are stored at
the same time as DTC P0420, troubleshoot those DTCS
first, then recheck for DTC P0420.
P0137, P0138: Secondary Heated Oxygen Sensor(secondary HO2S) (Sensor 2)
P0141: Secondary HO2S (Sensor 2) heater
1. Reset the ECM {see page 1'l-4}, then continue to
step 2 through 5 to reset the readiness code.
2. Start the engine. Hold the engine at 3,000 rpm with
no load (in neutral) untilthe radiator fan comes on.
Drive for about l0 minutes without stopping. Your
speeo can vary.
With the transmission in 4th gear, drive at a steady
speed between 50 62 mph (80-'100 km/h) for
30 seconds.
Repeat step 4 three times. Between each repetition,
close the throttle completely for 1 2 seconds. lf
the engine is stopped during this part of the
procedure, repeat steps 3, 4 and 5.
Check for a Temporary DTC with the scan tool.
Does the scan tool indicate Temporaty DTC
P0420?
YES Check the TWC. lf necessary, replace the
TWC.I
NO Check for readiness code completion. lfthe
readiness is complete, it was a interminent failure,
and the system is OK at this time. lf the readiness
code is incomplete, repeat steps 2 through 5.1

1. Check the diaphragm spring fingers for height
using lhe special lool and feeler gauge. lf the height
is more than the service limit, replace the pressure
ptate.

To prevent warping, unscrew the pressure plate
mounting bolts (A) in a crisscross pattern in several
steps, then remove the pressure plate (B).
Inspect the fingers of the diaphragm spring (A) for
wear at the release bearing contact area.
5. Inspect the pressure plate 1A) surfaceforwear,
cracks. and burning.

Flywheel Inspection
1. Inspect the ring gear teeth for wear and damage.
2. Inspect the clutch disc mating surface on the
flywheel for wear, cracks, and burning.
3. Measure the flywheel (A) runout using a dial
indicator (B) through at least two full turns. Push
against the flywheel each time you turn it to take up
the cra nksh aft th rust washer clea rance. lf the
runout is more than the service limit, replace the
flywheel and recheck the runout. Resurfacing the
flywheel is not recommended.
Standard (New): 0.05 mm (0.002 in.) max.
Service Limit: 0.15 mm (0.006 in.)

Mainshaft Thrust Clearance Adiustment
Special Tools Required. Mainshaft base 07GAJ-PG20130. Mainshaft holder 07GAJ-PG20110
1. Remove the 72 mm shim (A) and oilguide plate M
from the transmission housing (B).

Installthe 3rd/4th synchro hub (A), the distance
collar (B), the 5th synchro hub {C). distance collar
(D), and ball bearing (E) on the mainshaft (F), then
installthe assembled mainshaft in the transmission
housing (G).
lnstall the washer (H) on the mainshaft.
Measure distance O between the end of the
transmission housing and washer with a straight
edge and vernier caliper. Measure at three
locations and average the reading.
5.Measure distance @ between the end of the clutch
housing (A) and the bearing inner race (B)with a
straight edge and depth gauge. Measure at three
locations and average the readings.

Shim Selection Formula:
6, Select the proper 72 mm shim from the chan.
Follow the example below, and use the
measurements you made in steps 4 and 5:
(Basic Formula)
O+@ (0.8 * 0.11) = shim thickness (maximum)
O + O (0.8 + 0.17) = shim thickness (minimum)
. Add distance O (step 5) to distance O (step 4)
. 0.8 mm (0.031 in): Spring washer, a dimension in
the installation.. 0.11 mm (0.004 in): lvlinimum thrust clearance
. 0.17 mm (0.007 in): Maximum thrust clearance.
(For example)
2.32 + 0.15 - (0.8 + 0.11)= 1.56 mm (0.061 in.)
2.32 + 0.15 - (0.8 + 0.17)= 1.50 mm (0.059 in.)
Take the middle value of the minimum value and
the maximum value, and select the 1.53 mm
(0.060 in.) shim.
