Car Makes Strange Noise and Fails to Start After Shifting to P Gear Before Full Stop?

What does PEPS mean in cars?

PEPS in cars refers to the keyless system, also known as the Passive Entry Passive Start system. The function of the keyless system is simply that when the driver steps into a designated range, the system can recognize the authorized driver and automatically open the door; when leaving the vehicle, the door locks will automatically lock and enter an anti-theft state. The working principle of the keyless system is as follows: 1. Carry the car key to the vicinity of the vehicle (the car key must have power), when pressing the vehicle button or pulling the door handle, the vehicle will receive the ignition or unlock signal and send a signal to the low-frequency antenna. 2. After receiving the signal, the low-frequency antenna will send a low-frequency trigger signal to the car key. 3. The car key receives the low-frequency trigger signal and sends a high-frequency unlock signal. 4. The high-frequency receiver receives the high-frequency unlock signal, and the entire vehicle completes the unlocking or ignition process.

Should You Engage the Handbrake or Shift Gears First When Driving?

For manual transmissions, you should shift into gear first before releasing the handbrake. This is to prevent the vehicle from rolling backward if parked on a slope—releasing the handbrake first could cause the car to roll, but shifting into gear first ensures it stays in place. For automatic transmissions, the order doesn't matter as much; you can either shift into gear or engage the handbrake first, as long as safety is ensured. Here’s an introduction to manual and automatic transmissions: 1. A manual transmission uses a manual gear-shifting mechanical transmission (also called a manual gearbox, MT) to adjust the vehicle's speed. This means the driver must manually move the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed changes. 2. An automatic transmission does not require the driver to shift gears manually. The vehicle automatically selects the appropriate gear based on driving speed and traffic conditions.

What are the principles of various transmissions?

Transmission working principles are as follows: 1. Manual transmissions mainly consist of gears and shafts, achieving speed and torque variation through different gear combinations. 2. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque variation through hydraulic power transmission and gear combinations. The torque converter is the most distinctive component of an AT, consisting of a pump impeller, turbine, and guide wheel, directly inputting engine power to transmit torque and perform clutch functions. 3. If liquid is used instead of air as the medium for transmitting kinetic energy, the pump impeller will drive the turbine to rotate through the liquid, with a guide wheel added between the pump impeller and turbine to improve liquid transmission efficiency. Since the torque converter's automatic speed and torque variation range is not large enough and efficiency is relatively low, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system automatically operates the planetary gears according to engine working conditions, thereby achieving automatic gear shifting.

Is the GTR Truly a Supercar?

In terms of performance, the GTR undoubtedly qualifies as a top-tier supercar. However, a supercar is not merely about piling on performance specs. Historically, the GTR's predecessors were high-performance sports sedans under the Skyline series, not supercars. Here’s more about the GTR: 1. The Nissan GTR refers to a high-performance, high-reliability, high-power sports car produced by Nissan. After years of evolution and refinement of Nissan's Skyline sedan series, the GTR model emerged, becoming the pinnacle of the series and adored by countless fans. 2. The entire GTR lineup is equipped with a 3.8-liter V6 twin-turbocharged engine, delivering exceptional power with a maximum output of 357 kW and a peak torque of 588 Nm.

What does the faucet symbol on the car mean?

The faucet symbol on the car's dashboard is the engine malfunction indicator light. If it stays on, it indicates issues with the engine's combustion state, such as engine knocking, poor fuel quality, or unclean engine cylinders. Common causes include: 1. Poor contact or damage to the oxygen sensor, preventing the computer from identifying the engine's combustion state and causing partial failure of emission control functions. 2. Damage or poor contact in the camshaft or crankshaft sensors, leading to incorrect ignition timing, incomplete fuel combustion, and severely reduced efficiency. 3. Poor contact or parameter changes in the throttle motor, throttle sensor, air flow sensor, or absolute pressure sensor, causing the computer to inaccurately judge the air supply and resulting in incorrect fuel mixture ratios and incomplete combustion. 4. Resistance changes in the coolant temperature sensor, causing improper electronic fan activation times, deviating engine operating temperatures from specified values, or leading to high temperatures that reduce cylinder and pipe sealing, lowering engine efficiency. 5. Impurities or water in the fuel, increasing pollutants in the cylinders, causing poor spark plug discharge, incomplete combustion, and non-compliant emissions. 6. Coolant leaks, raising temperatures in various engine parts and altering sensor parameters. 7. Poor contact in the fuel pump, causing poor fuel injection and incomplete engine combustion.

Is the Engine Auto Start-Stop Technology Fuel-Efficient?

Overall, the engine auto start-stop technology is fuel-efficient, especially in urban or congested road conditions. The engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light). When it's time to move forward again, the system automatically restarts the engine. Here are some details about the engine auto start-stop technology: 1. By integrating an enhanced motor with idle start-stop functionality into a traditional engine, the car can completely shut off the engine when idle stop conditions are met. When the vehicle needs to start moving again, the idle start-stop motor system quickly responds to the driver's command, rapidly restarting the engine for seamless transition, thereby significantly reducing fuel consumption and exhaust emissions. 2. This technology can save up to 5% of fuel under normal driving conditions and up to 15% in congested traffic.
