Cap Testing
Testing

1. Remove the radiator cap, wet its seal with engine

coolant, then install it on the pressure tester.

RADIATOR

CAP

2. Apply a pressure of 93- 123 kPa (0.95- 1.25 kgf/cm2,

14-18 psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.
1. Wait until the engine is cool, then carefully remove

the radiator cap and fill the radiator with engine

coolant to the top of the filler neck.

2. Attach the pressure tester to the radiator and apply

a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -

18
psi).

(Commercially available)

3. Inspect for engine coolant leaks and a drop in pres-

sure.

4. Remove the tester and reinstall the radiator cap.

NOTE: Check for engine oil in the coolant and/or

coolant in the engine oil.

How to Set Readiness Codes

Catalytic Converter

NOTE:

• Do not turn the ignition switch OFF.

• When the battery negative cable is disconnected, all

readiness codes are cleared.

Required condition ('96 - 97 models):

• Ambient temperature between 32 - 95°F (0 - 35°C).

• Altitude below 2,400 m (7,874 ft.).

Required condition ('98 - 01 models):

Ambient temperature between 20 - 95°F (-7 - 35°C).

1. Connect the scan tool to the Data Link Connector

(DLC).

2. Start the engine. Hold it at 3,000 rpm with no load

(in Park or neutral) until the radiator fan comes on.

3. Drive for about 10 minutes without stopping on a

highway or freeway. Your speed can vary.

4. '96 - 97 models:

With the transmission in D4 position, drive at a

steady speed between 33 - 37 mph (53 - 59 km/h)

for 30 seconds.

'98 - 01 models:

With the A/T in D4 position, drive at a steady speed

between 50 - 62 mph (80 - 100 km/h) for 30 sec-

onds.

5. Do step 4 three times. Between each repetition,

close the throttle completely for 1 - 2 seconds. If the

engine is stopped during this part of the procedure,

go to step 3 and do the procedure again.

6. Check for the readiness code with the scan tool.

EGR Monitor

NOTE:

• Do not turn the ignition switch OFF.

• When the battery negative cable is disconnected, all

readiness codes are cleared.

Required condition ('96 - 97 models):

Altitude below 2,400 m (7,874 ft.).

1. Connect the scan tool to the Data Link Connector

(DLC).

2. Start the engine, and hold it at 3,000 rpm with no

load (in Park or neutral) until the radiator fan comes

on.

3. Drive at a steady speed with the transmission in D4

position, between 50 - 62 mph (80 - 100 km/h) for

more than 10 seconds.

4. With the A/T in D4 position, decelerate from 62 mph

(100 km/h) by completely releasing the throttle for

at least 5 seconds. If the engine is stopped during

this procedure, go to step 3 and do the procedure

again.

5. Check for the readiness code with the scan tool.
EVAP Leak Monitor

NOTE:

• When the battery negative cable is disconnected, all

readiness codes are cleared.

• If the engine is stopped while doing the procedure

between stops 6 and 16, do this procedure from step

1 again.

1. Make sure the gasoline level is 60 - 90% of fuel tank

capacity (not full).

2. Turn the ignition switch OFF.

3. Let the vehicle sit more than 8 hours.

4. '96 - 97 models:

Make sure the outside temperature is 32 - 95°F (0 -

35°C).

'98 - 01 models:

Make sure the outside temperature is 20 - 95°F (-7 -

35°C).

5. Connect the scan tool to the Data Link Connector

(DLC).

6. Start the engine and drive for about 15 minutes.

7. '96 - 97 models:

Keep the vehicle at a steady speed between 50 - 62

mph (80 - 100 km/h), without moving the accelera-

tor pedal, for about 1 minute.

'98 - 01 models:

Keep the vehicle at a steady speed between 50 - 70

mph (80 - 114 km/h), without moving the accelera-

tor pedal, for about 1 minute.

8. Stop the vehicle (do not stop engine).

9. Repeat steps 7 and 8 two more times.

10. Check for the readiness code with the scan tool. If

the readiness code does not set, go to step 11.

11. When ambient temperature is less than 32°F (0°C),

hold the engine at 3,000 rpm with no load (in Park

or neutral) until the radiator fan comes on.

12. When ambient temperature is more than 86°F

(30°C), remove the fuel fill cap, then install the fuel

fill cap.

13. After step 12, drive for about 20 minutes on a free-

way.

14. '96 - 97 models:

Keep the vehicle at a steady speed between 50 - 62

mph (80 - 100 km/h), without moving the accelera-

tor pedal, for about 1 minute.

'98 - 01 models:

Keep the vehicle at a steady speed between 50 - 70

mph (80 - 114 km/h), without moving the accelera-

tor pedal, for about 1 minute.

15. Stop the vehicle (do not stop the engine).

16. Repeat steps 14 and 15 two more times.

17. Check for the readiness code with the scan tool.ProCarManuals.com
