DIY : Customized Savvy TDC Sensor

I’m now at RS Auto, Puchong, servicing my dear Savvy. I guess most Savvy’s owners have heard about this workshop. It’s famous for solving Savvy’s little (a pain in the ass though) problem – TDC or speed sensor. I managed to change my TDC sensor here after a bit of googling.

If many have not known, Savvy has this simple problem with its TDC sensor connector. After a while it got loose. As the result, it’d be difficulted to start the engine, usually in the morning. Even sometimes, when the engine is idling in the middle of traffic jam, the engine just suddenly stops dead, and worse you cannot start it after a few times. However, the sensor itself is still A-OK. No need to be replaced or anything. What it needs is just a bit of altering the connector. You yourself can do it by your own.

5 Easy Steps To Alter Your Savvy TDC Sensor (Caution! Do it at your own risk)

  1. Just unscrew the TDC sensor
  2. Disconnect from main cable
  3. Cut the connector off from the main cable (your might want to observe which cable connects to which pin of the connector)
  4. Solder a new pair of wire about 3″ to the TDC pins/legs
  5. Rejoin those wires to the main cable accordingly

Walla! Now your Savvy is ready roll without anymore pain to start.

If you feel that you’re not that pro enough to DoItYourself and if you’re somewhere in Klang Valley area, might as well you drive to RS Auto in Puchong to get that little bugger replace for just RM30. They’ll take your TDC sensor and install an altered/customized one to your car. The one that they put into your car is not a non-ori unit. That’s why they take in your sensor so that they can customize it and resell it later.

I did mine there a month ago. The mechanic explained to me how they alter it. Anyway, I am not responsible if your Savvy blow off or something when you try this :). It’s just for the sake of sharing.

    when sensor dirty still need to clean , so it is for signal loss,
    ifsensor or flywheel dirty , it will soon accumulate dirts and making hard start again (also)

    Hi, thanks to you I managed to find out what’s really wrong with my Savvy. A few days back went to my usual mechanic but he couldnt solved the problem. Anyway, after reading ur story, today I went to the place and had my TDC replaced for RM30 only. Hope that solved my car problem. Btw, good news to all Savvy owners in Shah Alam, RS Auto will be moving to Seksyen 25 in Dec. A very good news to me especially since I live juz 10mins away 🙂
