If this sensor fails completely or provides inaccurate data, the ECU can make the fuel/air mixture too lean or too rich, causing ineffective combustion and a stalling engine. It’s the MAP/MAF sensor’s job to measure the air density entering the engine and calculate how much fuel should be used to provide the optimal fuel-to-air mixture based on that data. Most cars typically have one or the other. The most common sensor which can lead to your car stalling is the manifold absolute pressure sensor (MAP) or the mass air flow sensor (MAF). The car’s brain, the ECU, relies on data from these sensors to control the engine and prevent catastrophic engine damage. If you have been experiencing issues with your timing belt and need to have it replaced, you can get quotes from local mechanics in your area with M圜arNeedsA.If there’s nothing wrong with your car mechanically, the fault could lie in one of the dozens if not hundreds of sensors scattered throughout your vehicle. Replacing your timing belt is a lot less expensive than replacing an engine that is damaged because of a broken timing belt. When it’s time to replace your timing belt, you may need to consider replacing additional parts such as the tensioner, idler arm and water pump as these are also difficult to access. Timing belts aren’t easily accessible, which makes for an intensive labour job. Why is it expensive to replace a timing belt? The average cost of timing belt replacement can be anywhere from £300 - £500, but the price will all depend on if the belt has caused any other damage and the make, age and model of your car. How much does it cost to replace a timing belt? In most cases, major engine damage occurs due to the pistons not coming into contact with the valves. When a timing belt breaks or fails, the engine will not start or run, and the car needs to go in for repair. What happens if my car’s timing belt breaks or fails? Most timing belts will be hidden behind covers and engine parts, and because of this, it’s hard to perform a visual inspection of your timing belt. Why can’t I inspect my timing belt to see if it needs to be replaced? If the timing belt wear is great enough so the hydraulic timing belt tensioner cannot compensate for the slack, the noise will continue after starting up. Excess slack on a timing belt will cause a rattling nose or even a clanking noise depending on how severe the slack. Timing belt noises are very noticeable during start-up when oil pressure and flow is at its lowest. Timing belt issues are common in higher mileage vehicles. The recommended time for a timing belt replacement is anywhere between 70,000 to 100,000 miles unless a specific problem arises. When does a timing belt need to be replaced? The chain’s tensioner or guides connected to the chain may wear out also, causing the belt to fail completely. Over time, your timing belt will stretch due to internal component wear. What causes a timing belt to break or wear? If you don’t know what your car has, you can find all this information in the owner’s manual or just ask a mechanic.Ī timing belt synchronises the rotation of the crankshaft and camshaft ensuring the proper timing and allows the engine’s valves to open and close during each cylinder’s firing. If your car has a timing chain instead of a timing belt, a timing chain will rarely need to be replaced. My car has a timing chain, is that the same as a timing belt? Every time you use the engine, the timing chain is in use. A timing belt is a rubber belt with teeth located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
