VPS Diagnosis

Check all hoses for proper connection, restrictions, and leaks. Check the VC and E2 voltages. Apply the specified pressure and read sensor voltage output. The vapor pressure sensor is calibrated for the pressures found in the EVAP system, so apply only the specified amount to prevent damaging the sensor.

ASSIGNMENT NAME:

1. List the different types of Pressure Sensors used on cars?

2. Explain in detail the constructions and how a MAP (Manifold Absolute Pressure) sensor works?

3. What type of voltage signal is produced by a MAP and what would you expect to change as the engine goes from idle to W.O.T.?

4. Explain in detail the testing procedure of a MAP sensor.

5. Explain the need for a Barometric Pressure Sensor?

6. Explain the need for a Turbocharging Pressure Sensor and how does this compare to a MAP sensor?

7. Explain the need for a EVAP Vapor Pressure Sensor and how does this compare to a MAP sensor?
