Generally speaking, if one bar of the grille is broken, it can be easily repaired using 502 adhesive, and it will not affect the vehicle's driving safety at all. However, the repaired effect is certainly not as good as a brand-new one, so perfectionists would definitely opt for a complete replacement. Relevant information about the intake pressure sensor is as follows: 1. Introduction: The intake pressure sensor (Manifold-Absolute-Pressure-Sensor), abbreviated as MAP. It connects to the intake manifold via a vacuum tube, sensing the vacuum changes inside the intake manifold as the engine speed and load vary. The changes in internal resistance of the sensor are then converted into a voltage signal for the ECU to adjust the fuel injection quantity and ignition timing angle. 2. Working Principle: The intake pressure sensor detects the absolute pressure in the intake manifold behind the throttle. It senses the changes in absolute pressure within the manifold based on the engine speed and load, then converts this into a signal voltage sent to the engine control unit (ECU). The ECU uses the magnitude of this signal voltage to control the basic fuel injection quantity.

I've been driving a taxi for over ten years, and it's common to encounter a broken grille bar. The key is to assess the damage. If it's just a single plastic bar that's broken, there's no need to waste money on a full replacement. Most car grilles are modular, so you can remove and repair just the broken part. I've seen repair shops use epoxy adhesive to fix it for just a few dozen yuan. A full replacement could cost over five or six hundred, especially for newer models. And if you don't fix it, the impact is minimal unless it increases wind resistance at high speeds, leading to higher fuel consumption or water ingress risk. Last time my car had a broken bar, I fixed it myself with strong adhesive, and it's still holding strong after more than two years. I recommend checking if it affects air intake efficiency before deciding, and don't let shops pressure you into a full replacement right away. Regular care to avoid strong impacts can prevent this issue.

I remember when my car was just a year old, a piece of the grille broke off, and I was heartbroken. I drove to the dealership and asked, and the technician said there was no need to replace the whole thing. After inspection, they found it was just a local fracture and could be repaired with plastic welding. In the end, it was perfectly fixed for just 120 yuan. Minor damages like this are common in daily driving, and if they don’t affect the cooling efficiency, they can be left as is. If you replace the whole thing, you’d waste hundreds of yuan; it’s even less worth it for an older car. Later, I learned that some car owners use wire ties or add mesh protectors, which are both cost-effective and practical. If not repaired in time, it might deform or let water in over time, so it’s best to check repair options at a small shop early. When it comes to driving, be practical—don’t make a mountain out of a molehill.

A broken intake grille doesn't necessarily require full replacement. Its primary function is to protect the engine air intake, and a single broken slat usually doesn't obstruct functionality, though minor risks exist: potential water leakage onto the fan during rain or increased dust intrusion, which may lead to part corrosion over time. Quick diagnosis is crucial. For minor breaks, adhesive bonding or single slat replacement suffices; full replacement is only needed for severe damage. My experience shows most vehicle designs allow partial repairs, saving both time and money compared to complete replacement. Improper handling may actually increase risks.
