SOURCE: ATS(Air temp sensor) CTS( Coolant temp sensor)

I have a 351 but they are common sensors and should be located same places. ATC is on the side or bottom of the air intake filter box. The CTS should be located on the goose-neck where your Thermostat is housed; this is comming off the intake mannafold and into the radiator.

Hi. the fuel pressure sensor is part of the fuel pump assembly. You will have to remove the fuel pump to replace this. I would go ahead and replace the fuel pump while you are there.You will have to Pull the strainer off the fuel pump and discard it. remove the retaining clip for the fuel pressure regulator so that you can remove the fuel pressure regulator. Disconnect the electrical connections for the fuel pumps and the fuel level sensor. Remove the retaining clip for the fuel level sensor and remove the fuel level sensor by squeezing the locking tangs. the sensor is incorporated in this area.

Please rate and god bless.

SOURCE: need wiring diagram for the ecm on a 94 chevy s10

Throttle Position Sensor (TPS) is connected to the throttle shaft on the throttle body. It is a potentiometer with one end connected to 5 volts from the VCM and the other to ground. A third wire is connected to the VCM to measure the voltage from the TPS. As the throttle valve angle is changed (accelerator pedal moved), the output of the TPS also changes. At a closed throttle position, the output of the TPS is low (approximately 0.5 volts). As the throttle valve opens, the output increases so that, at wide-open throttle, the output voltage should be approximately 4.5 volts. By monitoring the output voltage from the TPS, the VCM can determine fuel delivery based on throttle valve angle (driver demand).

Po193 is registering an unpassable emission reading. What should we do?


This fault code is indicating a fault in your fuel rail pressure sensor. It is a very common fault with this model, usually just replacing the fuel pressure sensor that is located on your fuel rail will fix the fault. Here is a discription of it and location:

The Injection Pressure Sensor (IPS) :

  • is attached to the fuel injection supply manifold.
  • uses a replaceable O-ring seal.
  • senses the fuel pressure of the fuel injection supply manifold.
  • is referenced to the intake manifold vacuum.
  • sends electronic signals
REMOVAL

  1. Disconnect the battery ground cable. For additional information, refer to Battery.
  2. Relieve the fuel system pressure.
  3. Disconnect the fuel line from the IPR.

Disconnect the IPR electrical connector and the vacuum tube.

zjlimited_1904.jpg

  1. Remove the IPR.
    • Remove the bolts.
INSTALLATION

  1. To install, reverse the removal procedure. NOTE
    • Before installing the IPR, inspect and lubricate the O-ring seal with clean Super Premium SAE 5W-30 motor oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M3C153-G.
    • Hand-tighten the bolts before applying the final torque.
