EVAP PURGE CONTROL SOLENOID VALVE DUTY CONTROLLED AFTER

ENGINE COOLANT TEMPERATURE ABOVE 154"F (68'C)
Evaporative Emission (EVAP) Controls
Description:
The evaporative emission controls are designed to minimize the amount of fuel vapor escaping to the atmosphere. The
system consists of the following components:
A. Evaporative Emission (EVAPI Control Canister
An EVAP control canister is used for the temporary storage of fuel vapor until the luel vapor can be purged from the
EVAP control canister into the enqine and burned.
B. Vapor Purge ConirolSystem
EVAP control canister purging is accomplished by drawing fresh air through the EVAP control canister and into a pon
on the intake manifold. The purging vacuum is controlled by the EVAP purge control solenoid valve.
C. Fuel Tank Vapor Control System
When fuel vapor pressure in the fuel tank is higher than the set value of the EVAP two way valve, the valve opens and
regulates the flow ot fuel vapor to the EVAP control canister.

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.
