Where is the Fuel injection sensor on a 94 Jeep Grand Cherokee?

Answer 1

Components go from,

Fuel Pump, Fuel Filter, Fuel Line, Fuel Rail, Fuel Injectors, Fuel Pressure Regulator, back to Fuel Tank.

Fuel Controls/Sensors

Throttle Position Sensor tells computer where the trottle is and adjust fuel flow to injectors, Coolant Temp Sensor tells computer if engine is cold or hot and adjust fuel mixture, O2 Sensor tells the computer if it is running rich or lean to adjust fuel mixture.

There is no Fuel Injection Sensor for a 94. I would think someone is meaning the Fuel Pressure Regulator. If it is the 5.2 engine, at an idle your fuel pressure sould be approx 31 lbs. When youpull the vacume line from the Fuel Pressure Regulator, it should go up appox 8-10 pounds. I hope this helps you as I don't know what engine we are talking about.

There are several sensors which provide data for the fuel injection. Crankshaft position; near flywheel behind motor. Cam position; near balancer or distributor. O2; exhaust manifold outlet. Throttle position; exterior of throttle body. Coolant temp; thermostat housing, intake, or block. Intake temp; intake manifold. Intake pressure; intake manifold or connected to it by a vacuum line. Knock; engine block. Vehicle speed; transmission or speedometer cable.
