How is P1009 ACURA Code Repaired?

Start by checking the “possible causes” listed above. Visually inspect the wiring harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

What Does It Mean?

A tight timing chain or a damaged tensioner can also cause the P1009 code to trigger. Before replacing the timing chain or tensioner, check the engine oil level and condition. If necessary, replace the engine oil and filter with a factory-recommended oil weight.

Possible Symptoms

Engine light on (or service engine soon warning light)

P1009 ACURA Meaning

The Variable Valve Timing Control (VTC) system controls the phase of the intake camshaft. It uses oil pressure to operate the VTC actuator so that valve timing is optimized based on driving conditions. The Engine Control Module (ECM) / Powertrain Control Module (PCM) monitors the phase control command and actual camshaft timing using the Camshaft Position (CMP) sensor A. If an excessively advanced camshaft phase (compared to the commanded value) continues or when the camshaft phase is otherwise abnormal, a malfunction is detected and a DTC is stored.

P100A Description

VVEL (Variable Valve Event & Lift) is a system that continuously controls valve event and lift. The rotational movement of the drive shaft equipped with an eccentric cam is transmitted to the output cam via the rocker arm and two types of links to push the intake valve. The engine control module (ECM) determines the target valve lift based on driving conditions and sends the control signal to the VVEL control module. The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor and changes the output cam movement by shifting the link support point. As a result, valve lift continuously changes to improve engine power and response.

P100B Code Description

• The VVEL (Variable Valve Event & Lift) system controls the lift and opening of the intake valves.
• It uses a drive shaft, eccentric cams, rocker arms, and linkages to modify valve lift.
• The Engine Control Module (ECM) adjusts the valve lift based on driving conditions.
• The VVEL control module controls the rotation of the control shaft using the VVEL actuator motor.
• The goal is to optimize engine power and response.

Possible Symptoms

• Check Engine light illuminated.

Possible Causes

• Faulty VVEL actuator motor.
• VVEL actuator motor wiring harness open or shorted.
• Poor electrical connection in the VVEL actuator motor circuit.
• Faulty VVEL actuator assembly.
• Faulty VVEL ladder assembly.
• Faulty VVEL control module.

Repair Procedure

1. Visual Inspection:
   • Check the cables and connectors associated with the VVEL actuator motor.
   • Look for signs of damage: frayed wires, corroded connectors, bent or broken pins.
2. Component Verification:
   • If the visual inspection reveals no issues, test the VVEL actuator motor.
   • Check the VVEL actuator assembly.
   • Check the VVEL ladder assembly.
   • Check the VVEL control module.
   • If possible, test wire continuity.
