Pinpoint Tests E: Manifold Absolute Pressure (Map) Sensor: Introduction
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
This pinpoint test is intended to diagnose the following:
- harness circuits: MAP, SIGRTN, and VREF
- MAP sensor (14A464)
- PCM (12A650)
| Pin | Circuit |
|---|---|
| 2 | MAP (Manifold Absolute Pressure) |
| 1 | SIGRTN (Signal Return) |
| 3 | VREF (Reference Voltage) |
| Vehicle | Connector | Pin | Circuit |
|---|---|---|---|
| Transit | A | 28 | MAP |
| All other vehicles | B | 59 | MAP |
