1999 HONDA CR-V Air cool

Emission Control System
System Description
The emission control system includes, a Three Way
Catalytic Converter {TWC), Positive Crankcase Ventilation
(PCV) svstem and Evaporative Emission (€VAP) Control
system. The emission control system is designed to meet
federal and state emission standards.

!@ Do not smoke during this procsdura. Keep
any open tlame away from your work area.
1. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle,
Connect a tachometer.
Check and, if necessary, adjust the idle speed, (see
page 11-169, 170).
Warm up and calibrate the CO meter according to the
meter manufacturer's instructions.
Check idle CO with the headlights, heater blower, rear
window defogger, cooling fan, and air conditioner off.
(Canada) Pull the parking brake lever up. Start the
engine, then check that the headlights are off.
CO meter should indicate 0.1% maximum.

Three Way Catalytic Convertsr lTwcl:
The Three wav Catalvtic Converter (TWC) is used to
convert hydrocarbons (HC), carbon monoxide (CO), and

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.

. Replace the valve body as an assembly if any parts are worn or damaged.
. Checkall valvesforfree movement. lf anyfail toslidefreely, see Valve Body Repair on page l4-192.
'1. Hold the regulator spring cap in place while removing the stop bolt. The regulator spring cap is spring loaded Once
the stop bolt is removed, release the spring cap slowly so it does not pop out.
2. Reassembly is the reverse order of disassembly.
NOTE:
. Coat all parts with ATF during reassembly.
. Align the hole in the regulator spring cap with the hole in the valve body, thenpress the spring cap into the valve
