DTC Advanced Diagnostics: P08AE (1.5L Engine) (2025)
DTC P08AE : Neutral Position Sensor B Out of Range
General Description
Table A: Neutral position sensor output voltage
| NSS1 voltage | NSS2 voltage | |
|---|---|---|
| Neutral | 2.7 - 3.0 V | 1.35 - 1.5 V |
Neutral position sensor A and neutral position sensor B are semiconductor type that output different voltage characteristics. Each neutral position sensor outputs a voltage which depends on the condition is shown in Table A. The powertrain control module (PCM) judges whether it is in neutral or not from the neutral position sensor output voltage, and uses the information for various controls and auto idle stop system control (if equipped). Neutral position sensor A is for judging the neutral, and neutral position sensor B compares their output voltage to each other for malfunction detection. When the neutral position sensor B output voltage is out of a specified range for a set time, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter
Malfunction Threshold
The neutral position sensor B output voltage [Neutral Position Sensor 2] is 0.16 V or less, or 1.84 V or more for at least 6.0 seconds.
Possible Cause
The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Neutral position sensor B failure
- PCM internal circuit failure
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC and the freeze data can be cleared with the scan tool clear command.
