Nothing, as they say, was foreshadowed, but what happened happened. While driving in a traffic jam, a “garland” suddenly lit up on the dashboard and the car’s transmission went into emergency mode. Errors on the dash: TPMS system check required Engine check required SCBS system check required
Having connected the laptop and scanned the errors, I saw several errors in different blocks. But as I later realized, the main error code is P0472. In the PCM unit, this error is P0472 - Low voltage of the input signal of the pressure sensor in the exhaust system. In the OBDll unit, this error is P0472 - Abnormality in the exhaust gas back pressure sensor circuit.
Apparently the exhaust gas pressure sensor has failed. But which one exactly? I went to the OD with this question and received a paid consultation =))
The hero of the “triumph” is located here:
On a specialized forum I found a temporary solution: a “trick” of 2 resistors. But while I managed to find out exactly what resistors are needed (and even then I’m not sure that the information is reliable), they have already delivered me a new sensor. About resistors: “I won’t say exactly the nominal value, but you need to get 1V at the signal contact. I even annealed resistors on the machine, I didn’t worry.” - “two 2.2k worked great”
Here, in fact, is the new sensor. Order code SH02-18-211 C
(used to have a "B" at the end)
The new sensor is slightly different in appearance from the old one (partially covered by an orange rubber casing):
After “smoking” this manual a little, I decided that there was nothing complicated and began to change it. Below are short instructions for replacement. There really is nothing complicated, but perhaps it will be useful to someone. I cut the clamp to lift the wiring harness, under which there is a bolt for fastening the metal strip, which in turn holds the sensor hose:
The Japanese crossover of the CX-5 model range is equipped with modern safety features. The manufacturer paid special attention to the development of new methods that can reduce the likelihood of accidents on the road. To this end, the brand equipped the Mazda CX-5 with the SCBS system, which ensures safe braking of the car in city driving conditions.

This system can be triggered in winter by steam from the muffler of the car in front. I've had this happen a couple of times, when you stay too close to the person in front. And so I tested it, even on a dare, it didn’t let me down. The guy stood in front. But the trigger conditions must be met. These conditions are described in the operating instructions.
Maybe it doesn’t work on the steam, but on the car itself, since you’re staying so close? I try to keep my distance, I have never had it go off during operation, there were no false alarms and there were no real emergency situations
I had a very sharp response, before the barrier the system was ahead of me by a split second and the car stood up like a stake, it was a little stressful))
Thank you for the video! Stuntmen, stuntmen... (singing)
on an exiting pedestrian and should not be triggered. there is a laser radar there. I think the principle of operation is clear to everyone.
In short, you shouldn’t rely too much on this automation; judging by the videos, it doesn’t always work. Perhaps (!) if you miss the obstacle, it will save the situation, but not a fact.
rely on electronics, but don’t cry yourself)

saved my car 3 times out of three. For the first time in front of his wife, the guy decided to brake sharply. The second woman in front of me also slammed the brakes to the floor for no reason! the third time, the car turns. I go around it and again the woman (I can’t think of another word for stupid individuals of the female sex) sharply brakes, instead of continuing to drive into the turn. Many people find fault with the system and try to turn it off. Believe me, God forbid you yawn or some fool fusses in front of you, the system will not let you get screwed.
but it does not work at high speeds. at 90-100 it will not save you
