P02B0Cylinder 6 - Injector Restricted

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
These codes belong to an individual-cylinder fuel correction: a diesel's cylinder balance control measures each cylinder's crankshaft acceleration and adjusts its injection quantity; on petrol engines a cylinder-selective mixture control does the same. CARB requires the system to report when such a correction has used up its range or one cylinder causes an imbalance. P02B0 means the module attributes the deviation of cylinder 6 to an injector delivering too little – deposits or a sticking nozzle needle. GM and Ford use other codes for this (P0263 ff, P219A ff); no manufacturer document describing this code with thresholds was found, so the description follows CARB and published patents.
What you may notice
  • Check engine light on
  • Rough idle, vibration
  • Lack of power, higher consumption or smoke
Likely causes
  • LikelyDeposits or coking at the nozzle of cylinder 6
  • PossibleNozzle needle sticking
  • PossibleContaminated fuel or water
  • PossibleInjector circuit high-resistance
  • RareCompression loss mimicking low output
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
