| E-VES Diagnostic Trouble Codes (DTCs) | ||||||
|---|---|---|---|---|---|---|
| SPN = Suspect Parameter Number / FMI = Failure Mode Indicator | ||||||
| P-CODE | SPN | FMI | Description | Likely Cause(s) | ECU Response | Primary Course of Action |
| P1400 | 520324 | 3 | Diagnostic voltage too high | Diagnostic line (Pink / Black in harness, Brown
on signal converter) short to +12V Actuator power (Red / Black) removed |
ECU will not allow UP state. Fuel according to actual position |
Inspect PWM converter wiring for
chaffing / broken wires Ensure no loose pins in converter connector Replace signal converter if no wire / connector issues are found |
| P1401 | 5 | Diagnostic circuit open / grounded | Diagnostic line (Pink / Black in harness,
Brown on signal converter) open circuit Command wire (Dark Blue / White) short to GND Command wire (Dark Blue / White) open Actuator power (Red / Black) removed |
|||
| P1402 | 13 | Learn failure | Feedback voltage out of range during learn | ECU will force to DOWN state and fuel accordingly | Ensure battery is sufficient for relearn (maintains
11.5 volts during the entire procedure) Ensure Signal converter and / or actuator are not disconnected Ensure EV relay is connected, operational (clicks) and has no damage to terminal wiring Check for broken EV cable Perform cable measurement test per service manual Remove and inspect the valve assembly for causes for too little or too much travel. |
|
| P1403 | 12 | Hardware fault | Actuator position sensor failed Voltage too high during EV learn |
Replace EV Actuator | ||
| P1404 | 7 | Position not achieved | Actuator does not reach commanded state Will also trigger one of the following: P140A / B / C |
Fuel according to actual valve position | See actions for P140A / B / C | |
| P1405 | 2 | PWM set missing | Command wire (Dark Blue / White) to actuator
open circuit Command wire (Dark Blue / White) short to GND |
All valve positions allowed, Fuel according to actual position, When signal is returned, actuator will re-initialize | Inspect signal converter wiring
for chaffing or broken wires Ensure no loose pins on converter connector Replace signal converter if no wire / connector issues are found |
|
| P1406 | 520335 | 3 | Feedback position short to +12V | Feedback position (Dark Blue / Yellow on harness,
Grey on signal converter) short to +12V Actuator power (Red / Black) removed |
ECU will force to DOWN state and fuel accordingly | |
| P1407 | 5 | Feedback position circuit open / grounded | Feedback position (Dark Blue/Yellow on harness,
Grey on signal converter) short to GND Feedback position (Dark Blue/Yellow on harness, Grey on signal converter) open Actuator power (Red / Black) removed |
|||
| P1408 | 10 | Abnormal rate of change | Actuator achieves valve state too fast or resistance
too low Actuator power (Red / Black) removed Command wire (Dark Blue / White) short to +12V Command wire (Dark Blue / White) short to GND |
Position forced to last known state, fuel according to last known state | Inspect EV cable for damage or loose attachment at valve assembly | |
| P1409 | 520334 | 31 | Actuator overheat | Actuator Circuit board too hot Internal short circuit |
ECU will not allow UP state, Fuel worst case valve UP state | Replace EV Actuator |
| P1410 | 520337 | 31 | Learn default position | Actuator / Signal converter power (Red / Black) removed | ECU will not allow UP operation | Inspect Signal converter wiring for chaffing
or broken wires Ensure no loose pins on converter connector Check actuator wiring for broken wires, loose pins on actuator connector Replace signal converter |
| P140A | 520325 | 31 | Valve OPEN position not achieved | Valve UP position voltage out of range | Fuel according to actual valve position | Measure cable travel length Verify smooth valve operation by operating the cable by hand through its full travel Perform EV relearn procedure Remove E-VES assembly and inspect for heavy carbon build-up and / or damage |
| P140B | 520326 | 31 | Valve MID position not achieved | Valve MID position voltage out of range | ||
| P140C | 520327 | 31 | Valve DOWN position not achieved | Valve DOWN position voltage out of range | If occasional, this fault is nothing to be
concerned about If persistent: Measure cable travel length Verify smooth valve operation by operating the cable by hand through its full travel Perform EV relearn procedure Remove E-VES assembly and inspect for heavy carbon build-up and / or damage |
|
| P140D | 520328 | 5 | EV relay circuit open / grounded | EV relay supply power line is open | ECU will force to DOWN state and fuel accordingly | Inspect EV relay for corrosion
or loose terminals Replace EV relay |
| P140E | 3 | EV relay short to power | EV relay Grey / Yellow wire short to Power | |||
