P0564 Cruise control signal malfunction
• The PCM monitors the input voltage from the cruise control switch while the engine is running. PCM
determines cruise control signal malfunction if the input voltage from the cruise control switch is as follows for
120 s:
— Below 0.1 V.
— 1.4—1.9 V.
— 3.7—3.9 V.
— 4.5—4.6 V.
P0602 PCM programming error
• No configuration data in PCM
P0606 PCM malfunction
• PCM does not read DTC from output devices.
P0610 Control module vehicle options error
• PCM data configuration error
P0627 Suction control valve circuit open
• The PCM monitors the suction control valve operation circuit signal frequency at PCM terminal 94. If the
difference between the suction control valve operation frequency at PCM terminal 93 and the monitored
suction control valve operation circuit signal frequency at PCM terminal 94 exceeds the threshold, the PCM
determines that suction control valve open circuit.
P0628 Suction control valve circuit low input
• The PCM monitors the suction control valve circuit current while the engine is running. If the PCM detects the
circuit current is less than 1 A when the suction control valve is on, the PCM determines that there is a
malfunction in the suction control valve circuit.
P0629 Suction control valve circuit high input
• The PCM monitors the suction control valve circuit current while the engine is running. If the PCM detects
circuit current more than 1 A when the suction control valve is off, the PCM determines that there is am
malfunction in the suction control valve circuit.
P0661 Intake shutter solenoid valve (half) circuit low input
• The PCM monitors the output signal to the intake shutter solenoid valve when the intake shutter solenoid valve
is off. If the intake shutter solenoid valve voltage is less than 7.8 V when the intake shutter solenoid valve off,
the PCM determines that there is a malfunction in the intake shutter solenoid valve control circuit.
P0662 Intake shutter solenoid valve (half) circuit high input
• The PCM monitors the output signal to the intake shutter solenoid valve when the intake shutter solenoid valve
is on. If the intake shutter solenoid valve voltage is more than 7.8 V when the intake shutter solenoid valve on,
the PCM determines that there is a malfunction in the intake shutter solenoid valve control circuit.
P0664 Intake shutter solenoid valve (full) circuit voltage low input
• The PCM monitors the output signal to the intake shutter solenoid valve. If the intake shutter solenoid valve
voltage is less than 7.8 V when the intake shutter solenoid valve is on, the PCM determines that there is a
malfunction in the intake shutter solenoid valve control system.
P0665 intake shutter solenoid valve (full) circuit voltage high input
• The PCM monitors the output signal to the intake shutter solenoid valve when intake shutter solenoid valve is
on. If the intake shutter solenoid valve voltage is more than 7.8 V when the intake shutter solenoid valve is on,
the PCM determines that there is a malfunction in the intake shutter solenoid valve control circuit.
P0704 Clutch switch circuit malfunction
• The PCM monitors input voltage from the clutch pedal position switch while the engine running. If the input
voltage from the clutch pedal position switch does not change when the vehicle stops after accelerating to
more than 30 km/h {18.6 mph} and decelerating to 0 km/h {0 mph}, the PCM determines that clutch pedal
position switch circuit has a malfunction.
P0850 Neutral switch circuit malfunction
• The PCM monitors the input signal from the neutral switch when shifting. If the neutral switch signal is not input
even once even when vehicle speed is more than 10 km/h {6.2 mph} the shift lever is operated more than
five times, the PCM determines that there is a malfunction in the neutral switch circuit.
P1190 Calibration resistor circuit malfunction
• The PCM monitors the input voltage from the calibration resistor. If the PCM detects that the input voltage for
any cylinder is more than 4.8 V or less than 0.2 V, the PCM determines calibration resistor malfunction.
P1211 Fuel pressure higher or lower than desired pressure
• The PCM monitors the fuel pressure and calculates the fuel supply volume to the common rail using the fuel
pressure sensor input signal while the engine is running. If the fuel pressure or fuel supply volume to the
common rail is as follows, the PCM determines that the fuel pressure is higher or lower than the desired
pressure.
— Supply pump actual pressure is higher than threshold.
— Difference between two consecutive fuel supply to common rail volume from supply pump is more than one
fuel injection volume by fuel injector.
P1391 Glow plug circuit low input
• The PCM monitors the output signal to the glow relay when the glow relay is on. If the glow relay voltage is 1.0
