DTC P115E [MZI-3.7]
id0102d2881700
|
DTC P115E |
Throttle actuator control throttle body air flow trim at max limit |
|---|---|
|
DETECTION CONDITION
|
• During idle, the PCM monitors the throttle angle and air flow. If the air flow is determined to be less than expected, the PCM adjusts the throttle angle to compensate. The air flow reduction is typically the result of sludge buildup around the throttle plate. This DTC indicates the PCM has reached the maximum allowed compensation and is no longer able to compensate for the build up.
|
|
POSSIBLE CAUSE
|
• Sludge around the throttle plate
• PCM malfunction
