Conditions for Setting the DTC

P0089

• The high pressure fuel pump has exceeded the control limits. This condition exists when the Fuel Rail Pressure Regulator Command is 0° or greater than 92° for 12.5 s.

P00C6 Condition 1

• If the Fuel Rail Pressure Sensor is less than the target set point before the engine is cranked, the pressure rise diagnostic is used.
• The pressure rise diagnostic will fail if the Fuel Rail Pressure Sensor has not increased to the target set point within 9 s at -16°C (3.2°F) ECT or within 4 s if ECT is greater than 0°C (32°F).

P00C6 Condition 2

• If the Fuel Rail Pressure Sensor is greater than the target set point before the engine is cranked, the pressure fall diagnostic is used.
• The pressure fall diagnostic will fail if the Fuel Rail Pressure Sensor has dropped below 2 MPa (290 PSI) if the ECT is less than -16°C (3.2°F) or 0.6 MPa (87 PSI) if the ECT is greater than -16°C (3.2°F).

P228C, P2C1F

• The Fuel Rail Pressure Sensor is less than the Desired Fuel Rail Pressure by a predetermined value.
• The above condition exists for 10.00 s failures out of 12.50 s samples.

P228D, P2C20

• The Fuel Rail Pressure Sensor is greater than the Desired Fuel Rail Pressure by a predetermined value.
• The above condition exists for 10.00 s failures out of 12.50 s samples.

P2C1E

• This DTC determines when the high pressure pump control has reached to its max or min authority during Cataylst Warm up.
• The above condition exists for 10.00 seconds failures out of 12.50 Seconds samples.
