[RESOLVED] TPS Sensor Bad?

[jeremylee_7]

Hello, so I am getting a Throttle Position Switch CEL, i went and did a log with dsmlink and the tps stays at 0 and .4 volts. So i took off the hanress and checked the resistance at pins 1 &4 and 2 &4 and both were in spec (4500 ohms on 1 & 4, and 0-5k ohms on pin 2 & 4 as i hand rotate the throttle). So I checked the voltage at the tps pin at the ecu and it is getting .4 volts just like dsmlink says.

So I have low voltage coming from the tps but the resistance values are all good, so is my tps bad or is it more likely that i have bad wiring/ground?

Also, I checked the ecu harness sensor ground pins with voltmeter and both grounded ok.

Cool. It's hard to guess what sort of abuse the poor cars have been put through.
I'm glad you found it.

Ok link isn't showing voltage but I have 5 volts at the connector and the ecu pinout I had .63 volts last week and now nothing at all can anyone help.
