P1045 Fault Code: Understanding The Description And Troubleshooting Steps
The P1045 fault code refers to the Cylinder 1 Oil Supply Solenoid Valve Voltage being out of range. 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 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 P1045 fault code is triggered when the Powertrain Control Module (PCM) calculates that the delay in the measurement of current samples from the VVA Solenoid is greater than the required sampling period.
This indicates that the voltage of the Cylinder 1 Oil Supply Solenoid Valve is out of range. If you encounter this fault code, it is recommended to have the Cylinder 1 Oil Supply Solenoid Valve checked and replaced if necessary.
This will ensure proper functioning of the Multi-Air system and optimize the performance of your vehicle.
FAQ
If you see the engine light or service engine soon warning light on, the fault code P1045 could be the culprit. This code is often caused by a faulty Variable Valve Actuator (VVA) Solenoid, an open or shorted VVA Solenoid harness, a poor electrical connection in the VVA Solenoid circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, look out for broken, bent, pushed out, or corroded connector pins.
If you’re dealing with the P1045 fault code and your engine light is on, it’s time to take action. The most common cause is a faulty Variable Valve Actuator (VVA) Solenoid, but it could also be due to an open or shorted harness, poor electrical connection, or a faulty Powertrain Control Module (PCM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded pins. This simple step could be the key to resolving the problem and getting your engine running smoothly again.
If you come across damaged components or broken, bent, pushed out, or corroded connector’s pins while fixing the P1045 fault code, it is important to address these issues. Visually inspect the related wiring harness and connectors to identify any potential damage.
