Test DF: Step 3
3) Check MAP/BP Sensor Output With MAP/BP tester connected and key on, measure sensor output voltage. If voltage output is within range for altitude for vehicle being tested, remove MAP/BP tester and go to next step. If output reading is outside range, remove MAP/BP tester and go to step 5).
NOTE:
If possible, measure several known good MAP/BP sensors on available vehicles. Average voltage reading will be typical for your location on date of testing.
MAP SENSOR VOLTAGE OUTPUT
| Elevation (Feet) | Volts |
|---|---|
| 0 | 1.55-1.63 |
| 1000 | 1.52-1.60 |
| 2000 | 1.49-1.57 |
| 3000 | 1.46-1.54 |
| 4000 | 1.43-1.51 |
| 5000 | 1.40-1.48 |
| 6000 | 1.37-1.45 |
| 7000 | 1.35-1.43 |
