Maintenance Manual
3.1.2.9) Three-way solenoid valve
See Fig. 76-50
The 3-way solenoid valve (1) is installed on the engine
suspension frame or directly on airbox on newer engines.
■ CAUTION: In the event of physical damage, mechanical
defects or readings outside tolerance, replace
the part without delay.
- Inspection for physical damage.
- check for pneumatic passage
Disconnect the pressure connection lines. See 73-00-00
sec. 2.7.
- check the mixture enrichment (dynamic)
To do so, fit a T-fitting into line between solenoid valve and
float chamber to facilitate the measuring by pressure gauge
of the pressure at airbox pressure exceeding 1250 hPa.
The T-fitting may remain in place, but for standard opera-
tion it must be securely closed.
- Measure the resistance between the two terminals (2):
- Disconnect plug connection with wiring harness but
reestablish immediately after completion of check
and verify tight fit and engagement of catch.
- resistance at 20 °C (68 °F): 28.3 to 31.1 Ω
