webmaster Posted July 10, 2006 Report Share Posted July 10, 2006 The following is a procedure posted by Joe Grubbs to the Peugeot-L Mailing list back in 2002. Special thanks to Joe for letting us use this on 505turbo.com! TPS adjustment is a long and annoying process. You need to obtain some alligator test leads from RadioShack. The adjustment is performed with the engine off and the TPS disconnected. BTW unless the TPS is *grossly* out of adjustment, the engine will likely idle and handle light-part load just fine. It is unlikely that your problem can be fixed by just adjusting the TPS. - First measure the battery voltage - Multiply this number by 0.166 - Remember this number--this is going to be the TPS adjustment voltage, we'll call it "X" - Using the test leads, connect the battery across the resistor portion of TPS. The orange wire goes to (+) and the black wire goes to (-). Use an inline circuit breaker or fuse - Connect the (+) probe of the DVOM to the green wire (wiper) - Connect the (-) probe to the negative battery terminal - Test this setup by watching the meter. With a closed throttle it should be around 2 volts. Open the throttle all the way and it should read almost battery voltage - Loosen the two 3mm screws on the TPS a little and adjust until the reading on the meter is "X" - Carefully and equally tighten the screws--keep an eye on the meter because the adjustment will likely drift as you torque the TPS down. This is annoying part of the procedure Quote Link to comment Share on other sites More sharing options...
