DTC Chart: Powertrain Control Module (PCM)
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. REFER to: Diagnostic Methods .
PCM DTC Chart
| DTC | Description | Action |
|---|---|---|
| P0555 | Brake Booster Pressure Sensor Circuit | This DTC sets if the information in the brake booster vacuum sensor message is outside of the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
| P0556 | Brake Booster Pressure Sensor Circuit Range / Performance | This DTC sets if the information in the brake booster vacuum sensor message is outside of the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
| P0557 | Brake Booster Pressure Sensor Circuit Low | This DTC sets if the information in the brake booster vacuum sensor message contains a value lower than allowed by the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
| P0558 | Brake Booster Pressure Sensor Circuit High | This DTC sets if the information in the brake booster vacuum sensor message contains a value higher than allowed by the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
| P0559 | Brake Booster Pressure Sensor Circuit Intermittent | This DTC sets if the information in the brake booster vacuum sensor message is outside of the programmed set of parameters. This is most likely due to vacuum sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
| P1501 | Vehicle Speed Sensor Out of Self Test Range | This DTC sets if the information in the wheel speed sensor message is outside of the programmed set of parameters. This is most likely due to wheel speed sensor concerns, wiring harness concerns or vehicle communication concerns. Using a diagnostic scan tool, CARRY OUT the ABS module self-test. DIAGNOSE any ABS module Diagnostic Trouble Codes (DTCs). |
