tps sensor

I have a 1996 ranger 2.3l with a slight hesitation in the idle. i was wondering if you need to make an adjustment on the idle screw after i installed a new sensor. also im trying to trace the power steering pressure switch connector wire, im assuming it goes directly to the pcm. im not getting any voltage at the connector. i replaced the switch.my truck will die on me everytime when i make a left and right turn any ideas thx

No adjustments should be necessary to the idle screw. Have you cleaned the IAC (idle air control) solenoid yet? This or a dirty MAF would be my top suspect for your idle issue.

AFAIK, the power steering sensor is only ground anyway, so I don't believe there should be voltage present at the harness. I could be wrong there though - but I think it works just as the oil pressure sensor does.

How full is your tank when it dies around corners?

Also.... does this happen when turning AND braking? Maybe between turning and braking, your brake booster is leaking vacuum and causing it to die.

never checked the Maf , what about the EGR i guess you just replace it . i did clean the iac so the wires to the power steering connector go directly to the pcm thx

The PSPS does not have enough effect to cause the engine to die while turning, or shouldn't. The switch, by name, Power Steering Pressure Switch, is to notify the computer that the pressure in the power steering system is rising, and there will be the load from the power steering pump REAL SOON NOW, so bump the IAC number to prevent the engine from stalling.
I have a 2.3 with power steering I installed from old Ranger parts. It does not have a PSPS, and does not stall when turning, engine warm. Nor cold, now that I think of it.
I would check IAC operation overall before looking deeper. It should give fast idle cold, and then taper the idle as the engine warms up. If not, either the IAC or the temp sensor or the computer might be faulty. It, the IAC, should compensate for A/C compressor load. Energize the A/C and see if the idle stays solid or falters.
