–Steering wheel is in the straight-ahead position, etc.
4. Start engine and warm it up until engine coolant temperature
indicator points the middle of gauge.
Ensure engine stays below 1,000 rpm.
5. Run engine at about 2,000 rpm for about 2 minutes under no-
load.

DTC P0420 THREE WAY CATALYST FUNCTIONPFP:20905
On Board Diagnosis LogicEBS010Q8
The ECM monitors the switching frequency ratio of heated oxygen
sensors 1 and 2.
A three way catalyst (manifold) with high oxygen storage capacity
will indicate a low switching frequency of heated oxygen sensor 2.
As oxygen storage capacity decreases, the heated oxygen sensor 2
switching frequency will increase.
When the frequency ratio of heated oxygen sensors 1 and 2
approaches a specified limit value, the three way catalyst (manifold)
malfunction is diagnosed.
DTC Confirmation ProcedureEBS010Q9
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
TESTING CONDITION:
Open engine hood before conducting the following procedure.
Do not hold engine speed for more than the specified minutes below.
1. Start Engine and warm it up to the normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,00 rpm for at least 1 minute under no load.
4. Let engine idle for 1 minute.
5. Select “DTC & SRT CONFIRMATION” then “SRT WORK SUP-
PORT” mode with CONSULT-II.
6. Start engine.
7. Rev engine up to 2,000 to 3,000 rpm and hold it for 3 consecu-
tive minutes then release the accelerator pedal completely.
If “INCMP” of “CATALYST” changed to “COMPLT”, go to step 10
8. Wait 5 seconds at idle.

Fitting AdjustmentEIS009QH
LONGITUDINAL AND LATERAL CLEARANCE ADJUSTMENT
1. Remove hood lock assembly, loosen the hood hinge nuts and close the hood.
2. Adjust the lateral and longitudinal clearance, and open the hood to tighten the hood hinge mounting bolts
to the specified torque.
3. Install the hood lock temporarily, and align the hood striker and lock so that the centers of striker and lock
become vertical viewed from the front, by moving the hood lock laterally.
4. Tighten hood lock mounting bolts to the specified torque.
FRONT END HEIGHT ADJUSTMENT
1. Remove the hood lock and adjust the height by rotating the bumper rubber until the hood becomes 1 to1.5
mm (0.04 to 0.059 in) lower than the fender.

SURFACE HEIGHT ADJUSTMENT
1. Remove hood lock, and adjust the surface height difference of hood, fender and headlamp according to
the fitting standard dimension, by rotating RH and LH bumper rubbers.
2. Install hood lock temporarily, and move hood lock laterally until the centers of striker and lock become ver-
tical when viewed from the front.
3. Make sure that the hood lock secondary latch is properly
engaged with the secondary striker with hood's own weight.
4. Make sure that the hood lock primary latch is securely engaged
with the hood striker with hood's own weight by dropping hood
from approx. 200 mm(7.87 in) height.
CAUTION:
Do not drop hood from a height of 300 mm (11.81 in) or
more.
5. Move hood lockup and down until striker smoothly engages the
lock when the hood is closed.
6. When pulling the hood opener lever gently, make sure that front
end of the hood rises by approximately 20 mm (0.79 in) and that hood striker and hood lock primary latch
is disengaged. Also make sure that hood opener returns to the original position.
7. After adjustment, tighten lock bolts to the specified torque.
