What does P2088 code mean on a Kia or Hyundai? 

P2088 fault code means the “A" camshaft position actuator control circuit low bank 1 is faulty.  This means your Kia or Hyundai utilizes a variable timing system so that the timing of the camshaft can be adjusted in relation to the crankshaft. This improves fuel economy and increases perforamnce.  

Symptoms

  • Rough engine idle
  • Poor engine performance
  • Increased fuel consumption
  • Service soon light is on
  • Check engine light stays on
  • Engine misfire
  • Misfire fault codes presents

A faulty camshaft position sensor may cause the engine to P0300 P0301 P0302 P0303 P0304

Common Causes

In our case, the problem was a faulty camshaft position actuator. Keep in mind that P2088 may come on for a number of reasons. Common problems that can trigger the P2088 fault code include: 

  • Worn timing belt
  • Stretched timing chain
  • Defective camshaft variable timing solenoid
  • Faulty variable valve timing actuator
  • Engine oil level is too low
  • Oil light stays on
  • Blown fuse or fuse-able link in some cases
  • Misalignment of timing components
