P1321 Fault Code: Ignition Coil Secondary Circuit Malfunction Explained
The P1321 fault code refers to the Cylinder 1 Oil Supply Solenoid Valve Switch ON Time being immeasurable. This fault code is related to the Multi-Air system, which is an electronically controlled variable intake valve phase and lift system. In the Multi-Air system, each intake valve is controlled independently through an electronically controlled hydraulic link between the camshaft and intake valve.
The valve lift and timing can be adjusted infinitely.
The Multi-Air valve train includes a mechanical camshaft lobe that acts on a hydraulic pump, which is located between the camshaft intake lobe and the intake valve. This pump provides oil under pressure to a two-way electro-hydraulic solenoid valve called the Variable Valve Actuator (VVA) Solenoid. The P1321 fault code is triggered when the Powertrain Control Module (PCM) is unable to measure the time needed to turn on the VVA Solenoid.
This indicates a fault in the Cylinder 1 Oil Supply Solenoid Valve switch on time. It is important to address this fault code promptly to ensure proper functioning of the Multi-Air system and optimize engine performance.
A qualified technician should diagnose and repair the issue to resolve the P1321 fault code.
FAQ
If you see the engine light on or the service engine soon warning light, the fault code P1321 could be the culprit. This code can be triggered by a few different causes, including low engine oil level, contaminated oil, an incorrect oil filter, insufficient oil pressure due to a mechanical failure in the oiling system, or a faulty Variable Valve Actuator (VVA) Assembly. To fix this issue, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, inspect for any damage or broken components, and check for any bent, pushed out, or corroded connector pins.
If you’re dealing with the P1321 fault code and your engine light is on, it’s time to take action. The cause could be low engine oil level, contaminated oil, an incorrect oil filter, insufficient oil pressure, or a faulty Variable Valve Actuator (VVA) Assembly. To fix it, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to also check the possible causes mentioned earlier.
When resolving the P1321 fault code, start by checking for damaged components and connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By doing this, you can identify any issues that may be causing the engine light to turn on. Remember to also consider other possible causes such as low engine oil level, contaminated oil, incorrect oil filter, insufficient oil pressure, or a faulty Variable Valve Actuator (VVA) Assembly.
Wrap Up
If your engine light is on or you see the service engine soon warning light, it could be due to a few reasons. The engine oil level might be low, the oil could be contaminated, or the oil filter might be incorrect.
Another possibility is insufficient oil pressure caused by a mechanical failure in the oiling system or a faulty Variable Valve Actuator (VVA) Assembly.
To fix this issue, check the possible causes mentioned above.
Inspect the wiring harness and connectors visually, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.
