P0017: Crankshaft / camshaft timing correlation, bank 1 sensor B
The exhaust-camshaft and crankshaft signals on bank 1 are outside their expected relationship.
P0087: Fuel rail pressure too low
Measured fuel pressure fell below the pressure requested by the engine controller.
P0171: System too lean, bank 1
Fuel trim has reached a lean threshold because the ECU is adding more fuel than expected.
P0172: System too rich, bank 1
Fuel trim has reached a rich threshold because the ECU is removing more fuel than expected.
P0217: Engine coolant over-temperature condition
The engine controller recorded coolant temperature above its safe operating threshold.
P0507: Idle control system RPM higher than expected
Idle speed is higher than the ECU's target after it has reached the limit of normal control correction.
P0670: Glow-plug control module circuit
The engine controller detects a fault in the glow-plug module or its main control circuit.
P0671: Cylinder 1 glow-plug circuit
The glow-plug circuit for cylinder 1 has an electrical or current-consumption fault.
P0700: Transmission control system requested warning
The engine controller has been told by the transmission controller that a gearbox-related fault is present.
P0706: Transmission range sensor circuit range / performance
The selected gear or park/neutral signal is implausible for the transmission's actual state.
P0715: Input / turbine speed sensor circuit
The transmission controller cannot trust the input or turbine speed signal.
P0730: Incorrect gear ratio
The gearbox input and output speeds do not match the gear ratio the controller expected.
P0741: Torque converter clutch stuck off / performance
The torque converter clutch is not locking as expected or slip remains too high.
P0750: Shift solenoid A malfunction
The transmission controller detected an electrical or hydraulic problem with shift solenoid A.
P2187: System too lean at idle, bank 1
The ECU detects a lean condition mainly at idle, where small air leaks have a larger effect on mixture control.
P2279: Intake air system leak
The ECU detects extra unmetered air entering the intake system.
