Throttle position sensor OX66

Hola,

Does anyone know the resistance range for a throttle position sensor on a 2003 OX66 200hp? I'm getting 50-300 ohms.

I live on an island in a 3rd world country and do not have access to any mechanics with a computer to do a proper analysis. So far we have replaced the CDI and O2 sensor. The motor still exhibits the tendency to drop rpm after a brief run up.

Fuel pressure appears to be fine and the injectors are clean.

Any words of wisdom?

Cheers,
Mark
 
The TPS is a three wire potentiometer. Not a two wire variable resistor.

The TPS provides an output voltage to the CDI. The range is 0.50 volts (plus or minus 0.02 volts) at idle (pink wire to orange wire) to ~ 5.00 volts at WOT.

The output voltage is based on the input voltage. Input voltage is 4.75 ~ 5.25 volts.
 
Thank you for the response, most helpful.

The next question is, does anyone know where to find a complete wiring diagram? My on line search has led to a few dead ends. It needs to be downloadable as packages take about 3 weeks to get to me.

The motor is a S200 TXRB.

Headed out to check some voltages now.

Cheers.
