8. Mix the recommended antifreeze with an eoualamount of water in a clean container.
NOTE:
o Use only genuine Honda antifreeze/coolant.. For best corrosion protection. the coolant con_centration must be maintained year_round at50% minimum. Coolant concentrations less than50% may not provide sufficient protectionagainst corrosion or freezing.. Coolant concentrations greater than 60010 willimpair cooling efficiency and are not recom_mended.
CAUTION:
. Do not mix difforont brands ofar ilreeze/coolants.. Do not use additional rust inhibiiors or anti_rustproduqt3; they may not be compatible with thecoolant.

Start the engine and let it run until it warms up (theradiator fan comes on at least twicer.
Turn off the engine. Check the level in the radiator.add coolant if needed.

Engine Coolant Temperature (ECTI Sensor
The scan tool indicates Diagnostic Trouble code (DTC) P0116; A range/performance problem in the EngrneCoolant Temperature (ECT) Sensor circuit.
The ECT Sensor is a temperature dependant resistor (thermistor). The resistance of the thermistor decreases as the enginecoolant temperature increases as shown oetow.

1. Start the engine.
2. Remove the vacuum hose from the fitting on the
intake air duct, and connect a vacuum gauge to the
nose.
NOTE: Engine coolant temperature must be below

Raise and lower the engine speed, and make sure
the vacuum gauge reading changes as the engine
speed changes.
lf vacuum reading does not change check these
rtems:
. The vacuum lines of FIA system for misrouting,
leakage, breakage and clogging.
. The FIA controt valve for cracks or damage
. The cooling system (see section 10).
Hold the engine at 3,OOO rpm with no load (in Park
or neutral) until the radiator fan comes on, th€n let
it idle and recheck.
lf vacuum reading changes check these items:
a The FIA control valve for cracks or damage.
. The cooling system (see section 10).

Emission Gontrol System
System Description
The emission control system includes a Three Way Cata-lytic Convener (TWC), Exhaust Gas Recirculation (EGR)
system,. Positive Crankcase Ventilation (pCV) system andEvaporative Emission (EVAP) Control system. The emis-sion control system is designed to meet federal and stateemission standards.*: D16Y5 engine
Tailpipe Emission
Inspestion
@@ Do not smoke during ihis procedure. Keepany open flame away from your work area.
1. Start the engine. Hold the engine at 3,000 rpm withno load (in Park or neutral) until the radiator fancomes on. then let it idle.
2. Connect a tachometer.
Check and, if necessary, adjust the idle speed (see
page 11-220 - 223).
Warm up and calibrate the CO meter according to themeter manufacturer's instructions.
Check idle CO with the headlights, heater blower,rear window defogger, cooling fan, and air condition-er off.
NOTE: (Canada) Pull the parking brake lever up.Start the engine, then check that the headlights areoff.
CO mete. should indicate 0.1% maximum.
NOTE: '98 Dl6Y5 engine - lf the idle speed incress-es to 8101 50 rpm, this means the EVAp system ispurging the canister. To stop the purging temporari-ly. raise the engine speed above 1,000 rpm with theaccelerator pedal, then slowly release the pedal.

Test
CAUTION:
. To prev€nt transmission damage, do not t6st stall speed for more than ro sgconds at a time.. Do not shift the levor while raising the engine speed.. Bo sule lo remove the pressure gauge betoro testing stall speed.
'1. Engage the parking brake, and block the front wheels.
2. Connect a tachometer to the engine, and start the engine.
3. Make sure the Ay'C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the radiator fan comes on). shift into E position.
5. Fully depress the brake pedal and accelerator for 6 to g seconds, and note engine speed.
6. Allow two minutes for cooling, then repeat the test in @ and @ positions.
NOTE:
. Stall speed tests should be used for diagnostic purposes only,. Stall speed should be the same in o., E and E positions.
