When a Subaru car presents the P0016 Code, it is an indication that the Crankshaft Position and Camshaft Position Correlation is out of balance. This code appears when the battery voltage is 10.9 volts or higher, the engine speed is above 500 rpm, and the engine coolant temperature is at least 60°C (140°F). The code is triggered by the AVCS control, which is not in operation, and the target timing advance is set at 0°CA. The common symptoms of this code are engine stalls, improper idling, and possibly a decrease in engine performance. The causes of this code can range from oil pipe clogs, oil flow control solenoid valve clogs, intake camshaft being dirty or damaged, or even a timing belt problem. Knowing the causes of this code is critical in order to troubleshoot and resolve the issue.
Causes and Solutions of the Subaru P0016 Code
| Cause | Solution |
|---|---|
| Oil pipe clog | Change the oil pipe and clean it. |
| Oil flow control solenoid valve clogged | Replace the oil flow control solenoid valve. |
| Intake camshaft dirty or damaged | Clean or replace the intake camshaft, depending on the severity of the situation. |
| Timing belt problem | Replace the timing belt and inspect for any other related damages. |
When diagnosing a Subaru car, the P0016 Code is a common issue that can arise. This code appears when the battery voltage is 10.9 volts or higher, the engine speed is above 500 rpm, and the engine coolant temperature is at least 60°C (140°F). The code is primarily caused by oil pipe clogs, oil flow control solenoid valve clogs, intake camshaft being dirty or damaged, or even a timing belt problem. As a result, the engine stalls and shifts to improper idling, and the overall performance may be decreased. To troubleshoot this issue, it is important to address the causes, such as changing the oil pipe and cleaning it, replacing the oil flow control solenoid valve, replacing or cleaning the intake camshaft, and replacing the timing belt, with inspections for other related damages.
Oil Pipe Clog
When the oil pipe clogs, the oil flow is hindered and the engine is unable to receive the necessary lubrication, leading to friction and eventual stalling. To resolve this situation, the oil pipe must be replaced and cleaned so that the oil flow may be restored.
Oil Flow Control Solenoid Valve Clog
If the oil flow control solenoid valve is clogged, it prevents the engine from receiving the necessary oil. To fix this problem, the oil flow control solenoid valve must be replaced. This will help to regulate the oil flow and ensure that the engine receives the necessary lubrication.
Intake Camshaft Dirty or Damaged
The intake camshaft can become dirty or damaged for a variety of reasons, such as dirt and debris, or excessive wear and tear. If this occurs, the engine will be unable to receive the necessary oil, leading to friction and stalling. To address this issue, the intake camshaft must be cleaned or replaced, depending on the severity of the situation.
Timing Belt Problem
The timing belt is an essential component of the Subaru car’s engine. If it is not functioning properly, the engine will be unable to receive the necessary lubrication, leading to stalling. To fix this problem, the timing belt must be replaced and any other related damages must be inspected.
Conclusion
The Subaru P0016 Code is a common issue that can arise when diagnosing a Subaru car. This code appears when the battery voltage is 10.9 volts or higher, the engine speed is above 500 rpm, and the engine coolant temperature is at least 60°C (140°F). The code is primarily caused by oil pipe clogs, oil flow control solenoid valve clogs, intake camshaft being dirty or damaged, or even a timing belt problem. To troubleshoot this issue, it is important to address the causes, such as changing the oil pipe and cleaning it, replacing the oil flow control solenoid valve, replacing or cleaning the intake camshaft, and replacing the timing belt, with inspections for other related damages. By addressing these causes, the Subaru P0016 Code can be effectively resolved and the car can return to its optimal performance.
