(even glowing cherry red) So that means if say , engine power is lost andnever catches up?, then the TPS is NOT THIS PART BAD. First, find the sensor. oops wrong TBI there for your ECU. Loosen the throttle position sensor retaining screw with a Phillips-head screwdriver. 3) (<<>>===---. Adjusting the TPS switch is the ACT of Calibration. Part 1 of 2: Removing the throttle position sensor. If the pin is stuck , the voltage does not change, the TPS is bad. (just harnesses, if lucky). When they do, they usually freeze up or get stuck in a fixed position. TPpin is the Throttle angle pin (wiper) of the TPS, not the idle switch. When you cut the throttle and the TPS fails to close, the EGR cut will fail, as will the Dash-Pot effect, anti neck snapping feature , of cut fuel mode. PHOTO 3: 92-98 look same. Adjustment is not possible. S10forum is the community to discuss the S-Series, Chevrolet Colorado and GMC Canyon. (to avoid this nasty EFFECT) (varies from 1v to 4v as you move the throttle, typically) Remove grounding of the If you dont have a scan tool and you are working with a pre 1994 model : any of 3 throttle cables set tight, TV,cruise and A/T kick down cables (set wrong) The spec. That means it can't calculate the fuel and air ratio. (22 is stuck low) what do you mean? Locate the throttle position sensor on the throttle body, and unplug the attached electrical connectors from it. ( as you vary the throttle (with hand or foot) voltage must be linear and smooth at Pin B ) FYI: Throttle Position Sensor Replacement Cost The average price for replacing a throttle position sensor varies from $159 to $211. Select the Dash button which will open the Dash Display (Yellow Arrow). DTC errors, 31, 32 ,33 or 34, or starting in 1996 DTC errors P0101, 102,or 103 (These errors trip failsafe), DIY: crude way, ( super easy, super cheap , fast? (ohm meter) Then either find someone with a 95 or older S10 with the TB and ask them to read theirs. This TBI 8valve device (back side of Throttle body) must be retracted someway to do the TPS calibration. Theangleside never sets idle speeds, ever. Side one is called the IDLE SWITCH , the other side, is the TP (throttle position side or Throttle Angle), This side form a basic Potentiometer, (POT) or variable resistor. OK, the TPS now has power ! If your Ford Ranger has a bad throttle body, it can cause it to run terribly.
