Location of tps and map sensor on a 02 jeep grand cherokee 4.7l

Did you check for vacuum leaks?

What did it fail for?

Here you go.

Check this Jeep information about your engines...
3.7L -The Manifold Absolute Pressure (MAP) sensor is mounted into the front of the intake manifold with 2 screws.
4.0L - On the 4.0L six-cylinder engine the MAP sensor is mounted to the engine throttle body. On the 4.7L V-8 engine the MAP sensor is mounted to front of the intake manifold.
4.7L - The MAP sensor is located on the front of the intake manifold. An O-ring seals the sensor to the intake manifold.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I would change the TPS throttle position sensor and the Map/MAF are you sure its not the mass air flow?. I think your computer is fine it could be have a loose ground issues but computers dont go bad.

there is a rpm magnet that bolt on top of your transmission i had a jeep that done the same thing and repleced that and havent had a problem sinceits located on the left top side of your tranny has one little bolt that holds it in and a wire coming off of it that should fix your problem.

ITS INTHE INTAKE MANIFOLD MAP STANDS FOR MANIFOLD ABSOLITE PRESSURE THE SERVICE CODE SHOULD BE PO1106 HIGH VOLTAGE OR PO1107 LOW VOLTAGE IF YOU DON;T HAVE THESE CODES THEN ITS PROBELY NOT THE MAP SENSOR REPLACING COMPOUNETS SHOULD BE THE LAST STEP FORM A PLAIN IM NOT SAYING MAP IS NOT THE PROBLEM BUT BLINDLY REPLACEING SENSORS CAN BE A COSELY MISTAKE GET CODES

TPS is on the rear of the throttle body the throttle shaft that is attached to the gas pedal cable passes through the TB and goes directly into the TPS.

Go half way between the air cleaner box and the "carburetor". Up the 4" black air pipe, a wire harness plug plugs into the MAP sensor there. Also called MAS air flow sensor.

Look for noise in the TPS circuit that can cause TCC to lock and unlock.

the tps could cause the pcm to think the throttle is open further than it really is, adjusting injector pulsewidth to compensate. but. the 02 would see the rich condition, the idle would suffer and the idle air controller would open to compensate. all technical discussion aside, you need to check the 02 sensors output voltage while running. backprobe the output and make sure you're not getting over 1 volt and that it dances from about 200mV to 800mV at a high enough rate that your DVOM has a hard time keeping up with it. If you get a steady voltage, chances are the 02 sensor is shorted inside to either the ref. B+ or the heater B+. If it's not switching and the voltage is high, unplug it and check for voltage in the signal wire of the harness. could be a wiring issue before the 02 as well.
