Please help Tps & Map

[adiga101]

hi every one i need a help please
for tps the input is 4.69 the out put is 3.88 is it good ??

i test the map sensor
i test the section c its give me 5.0
i test the section b its give me 4.33 is it good ?

i feel there is a problem ?

the tps is new i try to move it this is the best reading i will have it for the input

I don't know either, but I think Blue XJ might. I know he has the info on the earlier TPS

found this http://www.allpar.com/trucks/jeep/cherokee-sensors.html for checking 87-90 cherokee MAP TPS testing,

TPS:
Terminals "A" and "D" (A/T) should be 5 volts.
Check sensor output voltage. To do so, disconnect voltmeter positive lead from terminal "A" and connect it to terminal "C" (M/T), or terminal "B" (A/T).
Maintain throttle plate in closed position (M/T and A/T). Ensure throttle linkage contacts stop. Note voltmeter reading. Output voltage should be .8 volt (M/T), or 4.2 volts (A/T)

MAP:
1) Inspect MAP sensor hoses and connections. Repair as necessary. With ignition on and engine off, test MAP sensor output voltage at connector terminal "B". (Marked on sensor body).
2) To verify wiring harness condition, test ECU terminal C-6 for same voltage described. Test MAP sensor supply voltage at sensor connector terminal "C" with ignition on.
3) Voltage should be 4.5-5.5 volts. Same voltage should also be at terminal C-14 of ECU wire harness connector. Using Diagnostic Tester (M.S. 1170), test MAP sensor ground circuit at terminal D-3 and terminal "A" of sensor connector.
4) Using an ohmmeter, test MAP sensor ground circuit at ECU connector between terminal D-3 of ECU connector and terminal B-11 with an ohmmeter.
5) If ohmmeter or diagnostic tester indicates an open circuit, inspect for a defective sensor ground connection, located on right side of cylinder block. If ground connection is good, ECU may need to be replaced.

Hope it helps.
