P008300 Variable camshaft timing (VCT) control circuit high (left hand bank)
VCT solenoid valve disconnected VCT solenoid valve to ECM PWM drive circuit: short VCT solenoid failure
For left hand bank VCT solenoid circuit tests, GO to Pinpoint Test G531330p30.
P008700 Fuel rail/system pressure - too low
Fuel rail pressure (FRP) sensor disconnected FRP sensor to ECM sensing circuit: high resistance or FRP sensor supply circuit: high resistance FRP sensor failure Fuel pump failure Fuel line leak Restricted fuel line
For FRP sensor circuit tests, GO to Pinpoint Test G531330p21. Check the fuel pressure, check the fuel lines, Fuel Tank and Lines - 4.2L NA V8 - AJV8/4.2L SC V8 - AJV8/3.0L NA V6 - AJ27/3.5L NA V8 - AJV8, VIN Range: G45704- >G99999
P008800 Fuel rail/system pressure - too high
FRP sensor to ECM wiring (supply/sense): short FRP sensor to ECM sense circuit: short circuit to FRP sensor ground circuit: high resistance FRP sensor failure Restricted fuel line Fuel pump short circuit to battery
For FRP sensor tests, GO to Pinpoint Test G531330p21. For fuel line tests, Fuel Tank and Lines - 4.2L NA V8 - AJV8/4.2L SC V8 - AJV8/3.0L NA V6 - AJ27/3.5L NA V8 - AJV8, VIN Range: G45704- >G99999 Check the fuel pressure, check the fuel lines, Fuel Tank and Lines - 4.2L NA V8 - AJV8/4.2L SC V8 - AJV8/3.0L NA V6 - AJ27/3.5L NA V8 - AJV8, VIN Range: G45704- >G99999
