P0662 SSV solenoid valve control circuit high
• The PCM monitors the SSV solenoid valve control voltage when the PCM turns the SSV solenoid valve on. If
the control voltage is more than 11.5 V, the PCM determines that the SSV solenoid valve control circuit voltage
is high.
P0703 Brake switch No.1 input circuit problem
• The PCM monitors the input signal from the brake switch No.2 when the following conditions are met. If the
input signal does not change while alternately accelerating and decelerating 8 times, the PCM determines that
there is a brake switch No.2 input circuit malfunction.
MONITORING CONDITION
— Vehicle speed: decelerating more than 30 km/h {19 mph} to 0 km/h {0 mph}
— Deceleration: more than 4 km/h {2 mph} per s
P0704 CPP switch input circuit problem
• The PCM monitors the input signal from the CPP switch when the vehicle speed is more than 30 km/h {19
mph}. If the input signal does not change while alternately accelerating and decelerating 10 times, the PCM
determines that there is a CPP switch input circuit malfunction.
P0850 Neutral switch input circuit problem
• The PCM monitors the input signal from the neutral switch when the vehicle is running. If the input signal does
not change while alternately running more than 30 km/h {19 mph} 8 times, the PCM determines that there is a
neutral switch input circuit malfunction.
P1260 Immobilizer system problem
• The keyless control module detects an immobilizer system malfunction.
P1574 TP sensor output incongruent
• The PCM compares the TP from TP sensor No.1 with the TP from TP sensor No.2 when the engine is running.
If the difference is more than the specification, the PCM determines that the TP sensor outputs are
incongruent.
P1577 APP sensor output incongruent
• The PCM compares the APP from APP sensor No.1 with the APP from APP sensor No.2 when the engine is
running. If the difference is more than the specification, the PCM determines that the APP sensor outputs are
incongruent.
P1686 Metering oil pump control circuit low flow side problem
• The PCM monitors the input signal from the metering oil pump switch when the metering oil pump stepping
motor is more than the standard step. If the input signal is off, the PCM determines that the metering oil pump
control circuit has a problem on the low flow side.
P1687 Metering oil pump control circuit high flow side problem
• The PCM monitors the input signal from the metering oil pump switch when the metering oil pump stepping
motor is less than the standard step. If the input signal is on, the PCM determines that the metering oil pump
control circuit has a problem on the high flow side.
P1688 Metering oil pump control circuit initial check problem
• The PCM monitors the input signal from the metering oil pump switch when the metering oil pump stepping
motor initial check is operating. If the input signal is on, the PCM determines that there is a metering oil pump
control circuit initial check problem.
P2004 APV stuck open
• The PCM monitors the input voltage from the APV position sensor when the PCM turns the APV motor off. If
the input voltage is more than 1.4 V, the PCM determines that the APV is stuck open.
P2006 APV motor control circuit IC problem
• APV motor control IC error.
P2008 APV motor control circuit/open
• The PCM monitors the APV motor control current when the engine is running. If the control current is less than
0.1 A or more than 10 A, the PCM determines that there is an APV motor control open circuit.
P2017 APV position sensor circuit problem
• The PCM monitors the input voltage from the APV position sensor when the engine is running. If the input
voltage is less than 0.2 V, the PCM determines that the APV position sensor circuit input voltage is low.
• The PCM monitors the input voltage from the APV position sensor when the engine is running. If the input
voltage is more than 4.8 V, the PCM determines that the APV position sensor circuit input voltage is high.
P2070 SSV stuck open
• The PCM monitors the input signal from the SSV switch when the PCM turns the SSV solenoid valve on. If the
input signal is on, the PCM determines that the SSV is stuck open.
P2096 Target A/F feedback system too lean
• The PCM monitors the target A/F fuel trim when under the target A/F feedback control. If the fuel trim is more
than the specification, the PCM determines that the target A/F feedback system is too lean.
P2097 Target A/F feedback system too rich
• The PCM monitors the target A/F fuel trim when under the target A/F feedback control. If the fuel trim is less
than the specification, the PCM determines that the target A/F feedback system is too rich.
