EVAP System
DTC Troubleshooting (cont'd)
DTC Pl457: EVAP Control System(EVAP Canister System)
Leakage
The fuel system is designed to allow specified
maximum vacuum and pressure conditions. Do not
deviate from the vacuum and pressure tests as
indicated in these procedures. Excessive pressure/
vacuum would damage the EVAP components or
cause eventual fuel tank system failure.
SpecialTools Required
Vacuum pump/gauge, 0-30 in.Hg A973X-041-XXXXX
This is a two-trip code. Once cleared, it cannot be
reproduced in one trip. Also, certain specific driving
and ambient conditions must occur before the ECfM will
complete the system checks, Additional test drives may
still not meet the specific conditions needed to16^r^.1' '^6 rh6 ^^.16
Follow these troubleshooting procedures carefully to
ensure the integrity of the system and to confirm the
cause of the problem or code.
NOTE: Fresh fuel has a higher volatility lhat creates
greater pressure/vacuum. The optimum condition for
testing is fresh fuel, and there must be less than a full
tank. lf possible, to assist in leak detection, add I gallon
of fresh fuel to the tank (as long as it will not fill the
tank), just before starting these procedures.
EVAP Canister Purge Valve Test

Transmission Fluid Inspection and
Replacement
'1. Park the vehicle on level ground, and turn the
engine OFF.
2. Remove the oilfiller plug (A) and washer (B), check
the condition of the fluid, and make sure the fluid is
at the proper level (C).
lf the transmission fluid is diny, remove the drain
plug (D) and drain the fluid.
A44 N.m{4.5 kgt.m,33 rbr.ftl
Reinstall the drain plug with a new washer, and
refill the transmission fluid to the proper level.
Oil Capacity
1.5 0 (1.6 US (F) at tluid change
1.7 0 {1.8 US qt) at overhaul
Always use Honda Manual Transmission Fluid
(MTF). Using motor oil can cause stiffer shifting
and noise because it does not contain the proper
additives.
Reinstall the oil filler plug with a new washer.5.
