Evaporative Emission (EVAP) Two Way Valve Testing
'97 model:
1. Remove the fuelfill cap.
2. Remove the vapor Iine from the EVAP two wayvalve on the fuel tank, and connect it to a T_fittingfrom a vacuum gauge and a vacuum pump asshown.

3. Apply vacuum slowly and continuouslv whilewatching the gauge. The vacuum should stabilizemomentarily at 0.7 - 2.0 kpa (5 - 1S mmHg, 0.2 _ 0.6in.Hg).
lf the vacuum stabilizes (valve opens) below0.7 kPa (5 mmHg,0.2 in,Hg) or above 2.0 kpa(15 mmHg, 0.6 in.Hg), install a new valve and retest.
4.Move the vacuum pump hose from the vacuum fit_ting to the pressure fitting, and move the vacuumgauge hose from the vacuum side to the pressureside as shown.

5. Slowly pressurize the vapor line while watching thegauge. The pressure should stabilize at 1.3 - 4.7 kpa(0 - 35 mmHg, 0.4 - 1.4 in.Hg).. lf the pressure momentarily stabilizes (valve
opens) at 1.3 - 4.7 kpa (10 - 35 mmHg, 0.4 _ 1.4in. Hg), the valve is OK.. lf th6 pressure stabilizes below 1.3 kpa fio mmHg,0.4 inrHg) or above 4.7 kpa (35 mmHg, 1.4 in.Hg),install a new valve and retest.

Apply vacuum slowly and continuously whilewatching the gauge.
The vacuum should stabilize momentarily at O.g _
2.1 kPa (6 - 16 mmHg, 0.2 - 0.6 in.Hg).lf the vacuum stabilizes (valve opens) below0.8 kPa (6 mmHg, 0.2 in.Hg) or above 2.1 kpa(16 mmHg, 0.6 in.Hg), install a new valve and retest.Move the vacuum pump hose from the vacuum fit-ting to the pressure fitting. and move the vacuumgauge hose from the vacuum side to the pressure
side as shown.
Slowly pressurize the vapor line while watching thegauge.
The pressure should stabilize momentarilv above1.0 kPa (8 mmHg, 0.3 in.Hg).a lf the pressure momentarily stabilizes (valve
opens) above 1.0 kPa (8 mmHg. 0.3 in.Hg), thevalve is OK.. lf the pressure stabilizes below ,|.0 kpa {g mmHg.0.3 in.Hg), install a new valve and retest.

Troubleshooting Procedures
Checking ths Diagnostic Trouble Code (DTC)
with an O8D ll Scan tool or Honda PGM Tsster
When the PCM senses an abnormality in the input or output systems, the El ('97 - 98) or E ('99 - O0) indicator light in thegauge ass€mbly will blink. When the 16P Data Link Connector (DLC) {located under the dash on the passenger's side) is
connected to the OBD ll Scan Tool or Honda PGM Tester as shown, the scan tool or tester will indicate the Diagnostic
Trouble Code (DTC) when the ignition switch is turned ON(ll).
HONDA PGM TESTER olOBD II SCAN TOOL
lf the E or E indicator light or the MIL has been reported on, or if a driveability problem is suspected, follow this proce-
dure:
1. Connect the OBD ll Scan Tool (conforming to SAE J1978) or Honda PGM Tester to the 16P DLC. (See the OBD ll ScanTool or Honda PGM Tester user's manual for specific instructions. lf you are using the Honda PGM Tester, make sureit is set to the SAE DTC Wpe).2. Turn the ignition switch ON (ll), and observe the DTC on the screen
3. Record allfuel and emission DTCS, A,,/T DTCS, and freeze data.
4. lf there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC (except for DTCP0700). DTC P0700 means there is one or more Ay'T DTC, and no Droblems were detected in the fuel and emissionscircuit of the PCM.
5. Wire down the radio station presets.
6. Reset the memory with the PGM Tester o. by removing the BACK UP fuse in the under-hood fuse/relay box for morethan 10 seconds.
7. Drive the vehicle for several minutes at speeds over 30 mph (50 km/hr), and then recheck for DTCS. lf the A/T DTCreturns, 9o to the Symptom-to Component Chart on pages 14-60 and 14-61 for the '97 models, and pages 14-62 and14-63 for '98 - 00 models. lf the OTC does not return, there was an intermittent problem within the circuit. Make sureall pins and terminals in the circuit are tight, and then go to step 8.8. Reset the radio Dreset stations, and set the clock.

4. Disconnect the heater hoses from the heater unit.
Engine coolant will run out when the hoses are dis-
connected; drain in into a clean drip pan.
CAUTION: Engino coolant will damage p8int. Ouickly
rinse any spill€d engine coolant Itom painted sur-
faces.
