‘A’ Camshaft Position Actuator Control Circuit High Bank 1


Table of contents

P2089 MERCURY Possible Causes

  • Faulty Variable Camshaft Timing (VCT) solenoid Bank 1
  • Variable Camshaft Timing (VCT) solenoid Bank 1 harness is open or shorted
  • Variable Camshaft Timing (VCT) solenoid Bank 1 circuit poor electrical connection

How do I fix code P2089 MERCURY?

  Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

Cost of diagnosing the P2089 MERCURY code

  The cost of diagnosing the P2089 MERCURY code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

When is the code detected

  The Powertrain Control Module (PCM) monitors the VCT circuit for high and low voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time.

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Long engine start

P2089 MERCURY Description

  The Variable Camshaft Timing (VCT) solenoid valve is an integral part of the VCT system. The solenoid valve controls the flow of engine oil in the VCT actuator assembly. As the PCM controls the duty cycle of the solenoid valve, oil pressure/flow advances or retards the cam timing. Duty cycles near 0% or 100% represent rapid movement of the camshaft. Retaining a fixed camshaft position is accomplished by dithering (oscillating) the solenoid valve duty cycle.
