Throttle Position Sensor Adjustment Question!
ok... the procedure for adjusting TPS
Procedure:
1.Start and run engine until at normal operating temperature and the fast idle cam is at idle position.
2.Turn off engine.
3.Remove the AWS hose that connects to the long curved inlet pipe and to the 4.AWS solenoid behind the throttle body.
5.Remove the hose from the pressure sensor on the firewall and tuck it down out of the way. Procedures 3 & 4 are to make room to reach the 2 TPS bolts.
6.Using the 7mm socket, 3/8" to 1/4" adapter, and 3/8" rachet, 1oosen the lower TPS bolt.
7.Using the 7mm socket and 1/4" L handle, barely loosen the top TPS bolt.
8.Connect the negative volt meter lead to a good ground point. I used one of the ground points in the diagnostic connector.
9.Insert the safety pin point into the 3F or 3G TPS connector between the wire and rubber weather seal. Using the alligator tip, connect the volt meter positive lead to the latch end of the safety pin.
10.Turn on the ignition without starting the engine. If there isn't a voltage reading, then readjust your ground and TPS connections until you do.
11.Note the voltages at closed and fully opened throttle.
12.Do the same for the other TPS connector point.
13.If all four voltages are not within the specified ranges, loosen the top TPS bolt and rotate the TPS until all four voltages are correct.
14.Tighten the 2 TPS bolts and reassemble everything. Do not over tighten the two TPS bolts. Their listed torque is 14 to 21 inch pounds!
14.Drive the car then readjust the idle air bleed if necessary.
Can someone please explain step 14? How do you air bleed? Someone help me pleeaasseeee
