BitchinZ Posted June 24, 2014 Share Posted June 24, 2014 I went to install my Speedhut coolant temp gauge which needs to use the supplied Speedhut temp sensor. I removed the stock sendng sensor for the stock gauge and now my car runs terrible and sounds like it wants to die. My question is does this sensor pictured send any info to the ECU? I thought it was just for the gauge. I have the CHTS in place, the only thing I changed was removing this. Those of you with a Speedhut or aftermarket coolant gauges how did you do the sensor with the stock system? Mine is an 83 L28ET with Z31 ECU.

BLOZ UP Posted June 24, 2014 Share Posted June 24, 2014 I thought the L2xE used 2, one for the dash gauge and one for the ECU. The Z31 does, I know that for a fact. Plug the old sensor back into the harness and find out. Quote Link to comment Share on other sites More sharing options...
Domzs Posted June 25, 2014 Share Posted June 25, 2014 The above picture is a temp sender ( thermal transmitter ) for the gauge only , has nothing to do with ECU . Check your work , make sure you didn't bump anything next to it . Good luck . Quote Link to comment Share on other sites More sharing options...
