Reading with vacuum hose disconnected approximately 3.3 bar (47 psi)
Fuel delivery rate at least 1 liter/min

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:
8200 - 10,500 ohms at 14°F
2200 - 2700 ohms at 68°F
300 - 360 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.
