Kicks exhaust temperature sensor issue

I'm having a bizarre issue with my 2019 Nissan Kicks with a gasoline engine. It’s got 191434 km on the clock. Lately, the check engine light keeps popping on, and I've noticed a definite dip in engine power. Fuel consumption is also noticeably higher. I've run diagnostics, and it points to a faulty exhaust temperature sensor. Could this be related to a potential leak in the exhaust system? Anyone else experienced similar?

A 2019 Nissan Kicks with high mileage is experiencing a check engine light, reduced engine power, and increased fuel consumption. Diagnostics indicate a faulty exhaust temperature sensor, which may be linked to a potential exhaust system leak. A similar case revealed that a small crack in the exhaust manifold was the actual issue, triggering the sensor. Repairing the manifold resolved the problem, restoring normal vehicle performance.

Reduced engine power and check engine light? Sounds familiar. I own a Kicks as well. Did you happen to notice any temperature fluctuation readings during diagnostics, especially unusual spikes?

Temperature fluctuation, you say? I recall seeing some inconsistent readings from the heat sensor, yes. But what does that say about the source of the problem really?

That confirms what I suspected. I had a similar issue, and while the sensor was flagging, the actual culprit was a small crack in the exhaust manifold. Get it checked at a reliable workshop, that sensor replacement will be 265€, it's not worth doing it yourself.

Thanks a lot for the insight! I took it to my local trusted workshop, and you were spot on. Small crack in the exhaust manifold triggered the sensor. 265€ later, all sorted and running smoothly again.
