15.35 With the TPs electrical connector discm resistance of the TPS with the throttle com: 34 Also, check the TPS reference voltege. With the ignition key ON (engine not running), install the positive (+) probe of the voltmeter onto the voltage reference wire. There should be approximately 5.0 volts sent from the PCM to the TPS. 35 Also check the resistance of the poten- tiometer within the TPS. Disconnect the TPS electrical connector and working on the sen sor side, connect the probes of the ohmme ter onto the round wire and the TPS signal (see illustration) 36 Now open the throttle with one hand and check the resistance again. Slowl resistance should be approximately ohm llgstration) In a
