Tps Pin Out, Cam Sensor, For Omex 600

Recommended Posts

peter

I'm using a TPS from a 8v turbo

 

The resistance changes between pins 1 and 3. so im guessing one is the signal wire and one the +5v and there for pin 2 is the ground?

 

 

How do you connect a cam sensor to the OMEX 600 the manual doesn't mention it?

Throttle pot recognition: how to tell which wire is which?

 

Any Throttle Potentiometer (TPS) has three wires - which are:

 

•+5v

 

 

•Signal

 

 

•Ground (GND)

 

 

Disconnect the TPS Sensor and work on the TPS sensor plug – not the wiring harness plug.

 

Using a resistance meter (automotive multimeter) find the two wires which do not vary their resistance when you move the TPS spindle. These two wires are the +5v and GND - you just don't know which way round they are! To determine this connect either one of the +5v/GND pair to the remaining wire – which by default must be the signal wire. Note the resistance value you see and operate the TPS spindle.

 

If the resistance value INCREASES as you operate the pot then the wire you are working with is the GND

If the value of the resistance DECREASES as you operate the pot then the wire you are working with is the +5v

600 doesn't do full sequential, you'd need the 710 for that, which can do 12 cylinder sequential :lol:

Between pins 1 and 3 is 3k ohm at closed throttle an 1k ohm full throttle.

 

Nothing changes between 1+2 or 2+3.

 

 

 

It doesn't do sequential!! It was a right faff fitting a cam sensor!!

So that's different to what stu8v said?

 

also if I use a gti6 TPS its does the opposite

 

Between pins 1 and 3 is 1k ohm at closed throttle an 3k ohm full throttle?!?!

Ok ignore what I said, I swapped a gti6 TPS with an 8v turbo one, the pins are the same but the TPS sits on the other end of the throttle spindle.

Not sure if anyone will still be following this, but what's the easiest way to fit a cam sensor to an xu 8v if you want full sequential?

I would use an RS cam pulley. Reduce it in width to match 8V dimension and mount a sensor somehow off the head, with a bracket etc.

thanks for the info.

 

Has anyone managed to fit a reliable cam sensor to an XU9JA or tried what peter said?

 

I'm looking at getting the engine in my turbo technics re-built and then ditching the fifth injector and upgrading to an aftermarket ecu.

 

Just trying to understand if full sequential is a realistic possibility (without massive hassle) ?

Another way is to put a sensor into the cam cover, above a cam lobe. As the lobe passes the sensor it will trigger. You'd have to think carefully about where you need the trigger event in the engine cycle and thus which lobe it needs to be above.
