RB26 Throttle Position Sensor Troubleshooting

RB26dett Throttle position sensor – HK skyline club

Normally you are looking for about 0.5 volts at the ECU for a RB26 TPS sensor at the ECU.

There are two connectors on the TPS sensors.  One is a simple open/closed switch, the other has a rheostat in it, and it measures the position of the throttle actuator, and feeds that 0.5 volt to 4.5 volt signal to the ECU.  The easiest way to check it is with a Consult type tool, so you see the signal the ECU is actually seeing. The R32 GT-R uses both connectors. The later cars do not.
