Pressure, Vacuum and Temperature Specifications

Fuel pressure
Fuel pressure with engine running 2.5 bar (36 psi)
Reading with vacuum hose disconnected approximately 2.7 bar (38 psi)

Fuel injectors
Resistance and delivery rate see "FUEL INJECTORS."
Leakage less than 1 drop/15 seconds at 3.0 bar (43 psi)

Cold start valve
Spray pattern an even cone with an angle of approximately 80°
Delivery rate 85cc ± 12% at 2.5 ± 0.05 bar (36 ± 1 psi)
Coil resistance 3 - 5 ohms at 20°C (68°F)

Oxygen sensor
Sensor (with engine running) 0.0 - 1.0vdc (depending on idle mixture)
Heater 0.5 - 1.3 Amperes

Coolant temp sensor resistance values:
70000 - 11,600 ohms at 14°F
2100 - 2900 ohms at 68°F
270 - 400 ohms at 176°F




Air temp sensor resistance values (measured between terminals 8 and 9):
8250 - 10,560 ohms at -9 - -11°C (12 - 16°F)
2280 - 2780 ohms at 19 - 21°C (66 - 70°F)
300 - 360 ohms at 79 - 81°C (174 - 178°F)
Note: Air temperature sensor is integral with the air flow meter and cannot be serviced separately. If sensor is defective, air flow meter must be replaced.
