To the point. no extra talking. Thanks

On older cars it can cause a no start too. My 94 bronco with minimal tech relies on the signal to calculate fuel ratio for operation. If it’s bad and reading too cold, it’ll flood the engine with fuel and if it’s the opposite, it’ll starve the engine of fuel which pretty much cuts the pulse to nothing and there’s nothing to ignite and make it run. Keep that in mind 👌🏽

Very helpful. I have 2 of the symptoms (Black smoke and error codes) but the car seems to run pretty much Ok when it reaches operating temperature. The garage is going to change the sensor anyway.

Would a bad sensor cause the engine to labor ping? Doesn't do it when engine is cold. Gauge doesn't show it getting hot

[codykemler]

Is it possible for it to have the opposite symptoms if it's reading your car is too hot when it's not causing the fans to stay on always and the gauge to read higher?

Need help please. I got a P0128 code for bad thermostat. I replaced it. The check engine light went off assuming because i took off the battery cable while doing the replacment. The light came back on 2 weeks later. Scanned the code and got the same P0128 code. Do i just need to delete it using the OBD2 scanner? No overheat, no leaks, temp is normal and good. Any suggestions? A buddy of mine said it could be bad coolant temp sensor but i didnt get the codes u provided in the video.

Hi, I used to have a bad engine noise. But when I changed the old corroded coolant temp sensor, the noise was gone for about 2 months. It was a temporary sensor, as it was purchased like 3 bucks. I plan to replace it as the noise is starting to come back.

[Brownguy]

[keithroberts]
