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.
MONITORING CONDITION
— Rear HO2S voltage is above 0.1 V
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 specification, the PCM determines that the target A/F feedback system is too rich.
P2101 Throttle actuator circuit range/performance
• The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay
on. If the input voltage is less than 5.0 V, the PCM determines that the drive-by-wire relay control circuit
voltage is low.
• The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay
off. If the input voltage is more than 5.0 V the PCM determines that the drive-by-wire relay control circuit
voltage is high.
P2107 Throttle actuator control module processor error
• Throttle actuator control module internal processor error
P2108 Throttle actuator control module performance error
• PCM internal malfunction.
P2109 TP sensor minimum stop range/performance problem
• The PCM monitors the minimum TP when the closed TP learning is completed. If the TP is less than 6.03% or
more than 18.7%, the PCM determines that there is a TP sensor minimum stop range/performance problem.
P2112 Throttle actuator control system range/performance problem
• The PCM monitors the throttle actuator control duty ratio when the engine is running. If the duty ratio is more
than 95%, the PCM determines that there is a throttle actuator control system range/performance problem.
P2119 Throttle actuator control throttle body range/performance problem
• The PCM compares the actual TP with initial setting TP when the ignition switch is off. If the difference is less
than the specification, the PCM determines that there is a throttle actuator control circuit range/performance
problem.
P2122 APP sensor No.1 circuit low input
• The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is
less than 0.35 V, the PCM determines that the APP sensor No.1 circuit input voltage is low.
P2123 APP sensor No.1 circuit high input
• The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is
above 4.8 V, the PCM determines that the APP sensor No.1 circuit input voltage is high.
P2127 APP sensor No.2 circuit low input
• The PCM monitors the input voltage from APP sensor No.2 when the engine is running. If the input voltage is
less than 0.35 V, the PCM determines that the APP sensor No.2 circuit has a malfunction.
P2128 APP sensor No.2 circuit high input
• The PCM monitors the input voltage from APP sensor No.2 when the engine is running. If the input voltage is
more than 4.8 V, the PCM determines that the APP sensor No.2 circuit has a malfunction.
P2135 TP sensor No.1/No.2 voltage correlation problem
• The PCM compares the input voltage from TP sensor No.1 with the input voltage from TP sensor No.2 when
the engine is running. If the difference is more than the specification, the PCM determines that there is a TP
sensor No.1/No.2 voltage correlation problem.
P2138 APP sensor No.1/No.2 voltage correlation problem
• The PCM compares the input voltage from APP sensor No.1 with the input voltage from APP sensor No.2 when
the engine is running. If the difference is more than the specification, the PCM determines that there is an APP
sensor No.1/No.2 angle correlation problem.
P2177 Fuel system too lean at off idle
• PCM monitors short term fuel trim (SHRTFT), long term fuel trim (LONGFT) during closed loop fuel control at
off-idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines
that fuel system is too lean at off-idle.
P2178 Fuel system too rich at off idle
• PCM monitors short term fuel trim (SHRTFT), long term fuel trim (LONGFT) during closed loop fuel control at
off-idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines
that fuel system is too rich at off-idle.
P2187 Fuel system too lean at idle
• PCM monitors short term fuel trim (SHRTFT) and long term fuel trim (LONGFT) during closed loop fuel control
at idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines
that fuel system is too lean at idle.
