Honda BAD IDLE FIX - Temperature Sensor

The car in this video is 1997-2001 Honda CRV. This fix may work for Hondas from 1980s to 2000s and more.
When the RPM is all over the place while idling on Honda, one reason may be the temperature sensor is failing. Cheap and easy to replace. Shown how it is done in the video with some other information.

You’re the best. I am a mechanic and replaced EVERYTHING on my crv except for this and having the idle issue. Everyone says IACV but I replaced mine with OEM and I didn’t know the coolant temp sensor could cause this too

I had this problem with my Honda Cr-v 2000 badly. I replaced the coolant temp sensor and that fixed the problem like 2/3 of they way. Still bad. I used a scantool to read the temp. It seemed stable and ide up/down problem started around 113 (45c) degrees Fahrenheit. I put a 2200 ohm resistor on there instead, permanently setting the temp to 73 deg Farenheit (23C) now it idles like a dream. I ordered another sensor om Amazon, maybe it will help.

Good idea with the resister.

what bluetooth OBD app & tool are you using? Looks fairly nifty and responsive.

[@minethisite2536]

App is called torque. And the tool is a random obd2 bluetooth from walmart
