Standard resistance
Notice:
Cold and hot mean the temperature of the coils
themselves. Cold is from -10 to 50°c (14 to
122°f) and hot is from 50 to 100°c (122 to
212°f).

Compressor lock sensor circuit
Description
This sensor sends 1 pulse per engine revolution to the air conditioning
amplifier. If the ratio of the
compressor speed divided by the engine speed is smaller than a predetermined
value, the air conditioning
amplifier turns the compressor off, and the indicator blinks at appro ...
Vc output circuit
Description
The ecm constantly generates 5 v power from the battery voltages supplied to
the +b (batt) terminal to
operate the microprocessor. The ecm also provides this power to the sensors
through the vc output
circuit.
When the vc circuit is short-circuited, the microprocessor in the ...
