I see a few posts where people have listed the actual value they get via Durametric for throttle position sensors and pedal encoder potentiometer, but no clear reference to what the values should be. 2004 986S US 3.2L For throttle position sensor 1 at idle, I get .64 volts; at 3000 rpm I get .84 volts For throttle position sensor 2 at idle I get 4.37 volts; at 3000 rpm I get 4.16 volts For pedal encoder potentiometer 1 at idle .76 volts; at 3000 rpm I get 1.08 volts For pedal encoder potentiometer 2 at idle .38 volts; at 3000 rpm I get .54 volts proper values or no??
Have recently had 4 new TPS sensors installed in my 997 MY08 C4S at local Porsche Indy. Tire pressures are displayed but system will not store the registration data after being "Set" through console or PMIS. With each ignition start receive message "Wheel change? Input new TPC settings". followed by flat tire and red error lights. Have driven car extensively between settings for system to "learn". Indy tried a known working control module without different result. I do not know mfg. of sensor units although shop has indicated that they have used them before in other vehicles without problems. Everyone is stymied frankly. Would appreciate any suggestions. Thanks.
