TCM inputted this signal through CAN communication line so TCM recognize driver's intension to control shift point.
TCM realized optimum shift point use this signal.
TCM set this code If detected not available TPS signal in condition that CAN signal is normal.
Item | Detecting Condition | Possible Cause |
DTC Strategy | ● Check signal | ● TPS |
Enable Conditions | ● Engine side CAN signal is normal ● CAN BUS is normal ● IG ON ● Battery voltage > 9V | |
Threshold Value | ● No signal of TPS | |
Diagnostic Time | ● Immediately | |
Fail Safe | ● No self learning control (priority : 1) |
The function with the higher priority will aiways take precedence. However, a low-priority is not overruled by a higher priority function.
Functions from different priority categories can also run in parallel. It is important to note which function will take precedence in this case.
In such an event it is possible for a substitute function with low priority not be carried out if a second, higher-priority function is present. This has been taken into account when compiling the priority list and is international.
The mechanical emergency run function must always have the highest priority, since from the electrical standpoint it is the only safe condition.

Is "Accelerator Pedal Position Sensor" output value within narmal range ?
 | ▶ Fault is intermittent caused by poor contact in the sensor's and/or TCM(PCM)'s connector or was repaired and TCM(PCM) memory was not cleared. Throughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.Repair or replace as necessary and go to "Verification Vehicle Repair" procedure. |
 | ▶ Refer to the "Engine DTC guide", Repair as necessary and go to "Verification vehicle Repair" procedure. |
After a repair, it is essential to verify that the fault has been corrected.
Connect scantool and select "Diagnostic Trouble Codes(DTCs)" mode.
Using a scan tool, Clear DTC.
Operate the vehicle within DTC Enable conditions in General information.
Are any DTCs present ?
| ▶ Go to the applicable troubleshooting procedure. |
| ▶ System performing to specification at this time. |
