P2662 code definition

This OBD-II trouble code is B Rocker Arm Actuator Sys Stuck On Bank 2. The letter B identifies the exhaust camshaft, and Bank 2 means the problem exists on the side of the engine without cylinder #1.

What the P2662 code means

The vehicle’s engine relies upon oil to run smoothly and prevent damage to its network of moving parts. The rocker arm actuator sends signals to the PCM (powertrain control module) in order to help regulate oil flow to the engine. These signals are interpreted by the computer as voltage readings; if the signal received by the PCM varies too much from the expected specifications, the computer senses a problem within the rocker arm actuator function and the P2662 code will set.

What causes the P2662 code?

According to automotive technicians, possible causes may include:

  • An open or short in the oil control valve wiring or connectors
  • A bad oil control valve
  • A bad rocker arm actuator
  • Low or incorrect oil condition
  • Mechanical engine failure
  • PCM failure (very rare)

What are the symptoms of the P2662 code?

The stored code may be accompanied by a lit Check Engine light. You may experience rough idle, choppy acceleration, poor engine performance, engine noises like tapping or ticking, or the vehicle may go into limp-in mode.

How does a mechanic diagnose the P2662 code?

Identifying this problem may include:

  • Checking the vehicle’s computer with a scanner in order to find out whether there are other accompanying codes, and whether they return after being cleared and test driving the vehicle
  • Checking the oil level and pressure
  • Visual inspection of the oil pressure sensor and rocker arm actuator screens
  • Inspection of the wiring and connections involved in the oil pressure sensor and rocker arm actuator
  • Testing the circuitry with a voltmeter
  • Monitoring live data wave form patterns with an oscilloscope

Common mistakes when diagnosing the P2662 code

The most common mistake is replacing sensors or other components without verifying that the oil level, condition, or pressure are not at fault. Technicians will also sometimes suggest replacing the PCM in an effort to alleviate this kind of trouble code, but true PCM failure is rare and should only be resorted to as a possible cause after a thorough diagnostic process has been carried out.

How serious is the P2662 code?

Any time you have a vehicle problem which affects the flow of oil to the engine, you should take it very seriously. If an oil-related issue isn’t remedied as soon as possible, it can lead to catastrophic engine failure.

What repairs can fix the P2662 code?

Repairs that may be made to rectify this fault include:

  • Oil pump replacement
  • Oil control valve replacement
  • Oil pressure sensor replacement
  • Rocker arm actuator replacement
  • Repair of opens, shorts, or other damage to the wiring and connectors involved in the rocker arm actuator and oil pressure sensor

Additional comments for consideration regarding the P2662 code

One thing that can be helpful with these types of fault codes is to research for technical service bulletins (TSB) related to your make and model of vehicle. These can yield information about commonly affected models, and let you know if the repair may be covered due to a recall.

Engine oil problems are nothing to mess around with, due to the risk of costly engine damage if the issue isn’t diagnosed and repaired correctly. In addition, this OBD-II trouble code may require the use of tools which most home mechanics don’t keep lying around. Consider consulting a professional technician so that you can be sure the repair is made efficiently and properly.
