When it comes to Ford vehicles, code P1016 is one of the most common diagnostic trouble codes (DTCs) that appears. The code is related to the wastegate control pressure that is higher than expected and typically sets when the measured wastegate vacuum sensor reading is higher than the expected reading by more than the calibrated threshold, and the fault timer has exceeded the calibrated time threshold. Though this code can be caused by a number of issues, such as a leak in the control tube between the turbocharger wastegate regulating valve and the wastegate actuator, leak in the tube between the vacuum reservoir and the turbocharger wastegate regulating valve, or a damaged turbocharger wastegate regulating valve, the typical difference threshold is 16.93 kPa (2.46 psi) and time threshold is 5 seconds. The related service bulletin SSM46438 provides further information regarding the Ford Code P1016.
Causes and Solutions of Ford Code P1016
| Cause | Solution |
|---|---|
| Leak in control tube between the turbocharger wastegate regulating valve and the wastegate actuator | Check for leaks and replace any faulty parts |
| Leak in the tube between the vacuum reservoir and the turbocharger wastegate regulating valve | Replace the tube, check for any other leaks, and repair accordingly |
| Damaged turbocharger wastegate regulating valve | Replace the valve and ensure all connections are secure |
| Typical difference threshold is 16.93 kPa (2.46 psi) and time threshold is 5 seconds | Check pressure and timing readings and adjust accordingly |
Leak in Control Tube
One of the major causes of Ford Code P1016 is a leak in the control tube between the turbocharger wastegate regulating valve and the wastegate actuator. When this happens, it can result in an unexpected increase in control pressure. In order to rectify this issue, the mechanic must check for any leaks and replace any faulty parts.
Leak in Vacuum Tube
Another cause of Ford Code P1016 is a leak in the tube between the vacuum reservoir and the turbocharger wastegate regulating valve. This can result in a decrease in the pressure reading and will need to be addressed. Here, the mechanic should replace the tube, check for any other leaks, and repair accordingly.
Damaged Turbocharger Wastegate Regulating Valve
The third common cause of Ford Code P1016 is a damaged turbocharger wastegate regulating valve. This can result in an inaccurate pressure reading and will need to be repaired or replaced in order to resolve the issue. Here, the mechanic should replace the valve and ensure all connections are secure.
Pressure and Timing Readings
Finally, the typical difference threshold for Ford Code P1016 is 16.93 kPa (2.46 psi) and time threshold is 5 seconds. In order to ensure that the readings are accurate, the mechanic should check the pressure and timing readings and adjust accordingly.
Conclusion: Resolving Ford Code P1016
Ford Code P1016 is one of the most common diagnostic trouble codes (DTCs) that appears in Ford vehicles. Though this code can be caused by a number of issues, such as a leak in the control tube between the turbocharger wastegate regulating valve and the wastegate actuator, leak in the tube between the vacuum reservoir and the turbocharger wastegate regulating valve, or a damaged turbocharger wastegate regulating valve, the typical difference threshold is 16.93 kPa (2.46 psi) and time threshold is 5 seconds. With the right diagnosis and repair, the Ford Code P1016 can be resolved quickly and efficiently.
