Comprehensive list of parameters related to an engine, its systems, and sensors:
1. Electrical Parameters
Resistance:
Starter Motor Solenoid: 0.4 to 2 ohms
Ignition Coil Primary: 0.5 to 2 ohms
Ignition Coil Secondary: 6,000 to 15,000 ohms
Coolant Temperature Sensor: Changes based on temperature (e.g., 200-500 ohms at high temp)
Crankshaft Position Sensor: Varies depending on the sensor (500-1,500 ohms)
Oxygen Sensor Heater Circuit: 4 to 40 ohms
Throttle Position Sensor: Typically 1-10 ohms
Voltage:
Battery Voltage: 12.6V (fully charged) / 14.0-14.5V (when charging)
Sensor Output (e.g., TPS, MAP): 0.5 to 4.5V
Current:
Starter Motor Draw: 100-200 amps (depending on engine size)
Fuel Pump Current: Typically 5-10 amps
2. Pressure Parameters
Fuel Pressure:
Petrol Engine (Fuel Injected): 30-60 psi
Diesel Engine (Common Rail): 20,000 to 30,000 psi
Oil Pressure:
At Idle: 10-20 psi
At Higher RPM: 40-70 psi
Manifold Absolute Pressure (MAP): 0.5 to 1.5 bar (7-22 psi)
Exhaust Backpressure: Typically below 3 psi, but depends on engine and load
3. Vacuum Parameters
Intake Manifold Vacuum:
At Idle (Petrol Engine): 17-22 inHg (inches of Mercury)
During Deceleration: Up to 25 inHg
Brake Booster Vacuum: Similar to intake manifold vacuum, typically 17-22 inHg
EGR System Vacuum: 15-20 inHg when EGR valve is activated
