WATER TEMPERATURE SENSOR
1. Measure:
●
Water temperature sensor resistance
(at the specified temperature)
Out of specification
→
Replace.
Water temperature sensor
resistance:
0 ˚C (32 ˚F): 24.0 ~ 37.1 k
Ω
100 ˚C (212 ˚F): 0.87 ~ 1.18 k
Ω
200 ˚C (392 ˚F): 0.104 ~ 0.153 k
Ω
Measurement steps:
●
Ice the water temperature sensor and
measure the resistance.
●
Suspend the water temperature sen-
sor in a container filled with oil.
●
Slowly heat the oil.
●
Measure the resistance when the spec-
ified temperature is reached.
EXHAUST TEMPERATURE SENSOR
1. Measure:
●
Exhaust temperature sensor resis-
tance (at the specified temperature)
Out of specification
→
Replace.
Exhaust temperature sensor
resistance:
300 ˚C (572 ˚F): 73 ~ 241 k
Ω
600 ˚C (1,112 ˚F): 0.86 ~ 1.58 k
Ω
900 ˚C (1,652 ˚F): 64 ~ 90
Ω
Measurement steps:
●
Heat the exhaust temperature sensor
using an electric furnace or equivalent.
●
Measure the resistance when the spec-
ified temperature.
