I have a 2013 ford fiesta and I am trying to locat the input seed sensor can anyone tell me where can I find it?

thank you.

 

There are two input speed sensors. Do you have any fault codes to show which sensor it is.

 

yes. p0715 turbine/input shaft speed sensor circuit

 

PINPOINT TEST D : INPUT SHAFT SPEED SENSOR 1 OR 2 FAULT
D1 READ AND RECORD ALL DTCS
Connect the scan tool.
Using the diagnostic scan tool, retrieve all DTCs .

Are ISS sensor 1 and 2 DTCs present?

Yes For DTCs P06A6, P0715, P0716, P0717 and/or P0718, GO to D2. For DTCs P06A7, P2765, P2766, P2767 and/or P2768, GO to D6.
No PERFORM the Speed Sensor Test, REFER to Transmission Adaptive Learning.


D2 CHECK THE ISS SENSOR 1 POWER CIRCUIT FOR VOLTAGE
Ignition OFF.
Disconnect: ISS Sensor C143 .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
Ignition ON.
Measure the voltage between:


Positive Lead Negative Lead
Pin Circuit Pin Circuit
C143-2 — — Ground


Is the voltage greater than 10.5 volts?

Yes GO to D3.
No GO to D4.


D3 CHECK THE ISS SENSOR 1 RETURN CIRCUIT
Measure the voltage between:

No GO to D4.


D4 CHECK THE ISS SENSOR 1 CIRCUITS FOR AN OPEN
Ignition OFF.
Disconnect: TCM C1750B .
Disconnect: ISS Sensor C143 .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
Measure resistance between:


Positive Lead Negative Lead
Pin Circuit Pin Circuit
C143-1 — C1750B-10 —
C143-2 — C1750B-21 —


Are the resistances less than 5 ohms?

Yes GO to D5.
No REPAIR the circuit.


D5 CHECK THE ISS SENSOR 1 CIRCUITS FOR A SHORT TO GROUND
Measure the resistance between:


Positive Lead Negative Lead
Pin Circuit Pin Circuit
C143-1 — — Ground
C143-2 — — Ground


Are the resistances greater than 10,000 ohms?

Yes INSTALL a new ISS sensor 1. REFER to Input Shaft Speed Sensor — No. 1. PERFORM the Speed Sensor Test, REFER to Transmission Adaptive Learning.
No INSPECT and REPAIR the circuit shorted to ground. If a short to ground was not found, INSTALL a new TCM . REFER to Transmission Control Module (TCM). PROGRAM the TCM with the latest calibration, REFER to Transmission Adaptive Learning.


D6 CHECK THE ISS SENSOR 2 POWER CIRCUIT FOR VOLTAGE
Ignition OFF.
Disconnect: ISS Sensor 2 C164 .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
Ignition ON.
Measure the voltage between:


Positive Lead Negative Lead
Pin Circuit Pin Circuit
C164-1 — — Ground


Is the voltage greater than 10.5 volts?

Yes GO to D7.
No GO to D8.


D7 CHECK THE ISS SENSOR 2 RETURN CIRCUIT
Measure the voltage between:


Positive Lead Negative Lead
Pin Circuit Pin Circuit
C164-1 — C164-2 —


Is the voltage greater than 10.5 volts?

Yes INSTALL a new ISS sensor 2. REFER to Clutch Motor — No. 2. PERFORM the Speed Sensor Test, REFER to Transmission Adaptive Learning.
No GO to D8.


D8 CHECK THE ISS SENSOR 2 CIRCUITS FOR AN OPEN
Ignition OFF.
Disconnect: TCM C1750B .
Disconnect: ISS Sensor 2 C164 .
Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
