Sounds like it may have failed fully with both sensor channels having went bad or a board issue (likely a bad 5V regulator would be my guess.) Someone with more experience on this will confirm/deny.

If you get no voltage to the outer pins 1 & 5 after switching ignition to Pos II then I would worry. Is throttle plate moving and clicking with ignition on? You have about 8 secs to test and within that time you should see throttle flap movement. I've seen afew corroded potentiometer strips whic...

If you hear the click the throttle has power to the flap.

If you ground your meter on one lead to strut top or other ground and try to get a voltage on either pin 2 OR pin 4 that will tell you if the board has the ability to accept the Sacer sensor

No need to test the throttle flap any more; the flap is working. There are 2 different circuits at play on the 5 pin side. 1) Throttle flap power using pins 1 & 5 2) Sensor 1 resistor using pins 2,3 & 4 The 2 circuits work independently of each other. Once pin 2 receives the variable voltage...

Voltage is ONLY present between Pins 1 & 5 within 8 secs of turning on ignition to Pos II on a functional throttle. It's safe to say that if you hear the throttle operating, the voltage to the flap is there. The other circuit (between pins 2 & 4) requires power for the potentiometer. As I me...

Golf2 "With the TPS disconnected, I could see 7v on pin 2 (ETM side)"

Which is the ETM side for you? The 5 pin side or the 3 pin side?

You should be fine to go ahead and install the Sacer TPS.

Output leads for throttle angle to the connector are yellow/green and red/blue. Once the Sacer is fitted power it up and measure the voltages at those leads. If you rotate the flap by hand they should vary.

When installed the sensor output on both sides should be between 1.35 and 1.45V.

Good luck

Hey NP. Glad it worked out!!
