Here are the reasons why the reverse gear R does not respond in an automatic transmission car: Fault reasons: If components such as the transmission, oil pump, torque converter, control circuit, solenoid valve, or switch malfunction, the reverse gear may fail to engage. Operational reasons: If the electronic parking brake is not released or the gear shifting method is not properly executed, the reverse gear may also become ineffective. Transmission issues: In most cases, the inability to reverse in an automatic transmission car can be attributed to transmission problems. It is necessary to check whether the main oil pressure and gear oil pressure are normal, whether the gear switch signal is normal, and whether the circuit from the transmission computer to the shift solenoid valve is functioning properly.

Where is the ETC usually installed?

The installation position of the ETC for small cars is generally in the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed in the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 and 90 degrees. For vehicles with anti-explosion film or those that have been retrofitted with anti-explosion film, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave skylight area. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for an ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If the application is not made by the owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed, and the vehicle must be registered under the name of an individual aged between 18 and 60. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After the electronic tag is installed, the windshield will press the anti-removal lever in. If the tag is removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing area is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to avoid automatic toll deduction for the wrong vehicle. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information and thus failed toll deduction. When using a debit card linked to ETC, insufficient balance may also lead to failed toll deduction.

What are the reasons for the persistent engine warning light in Peugeot 2008?

Sensor malfunctions, vehicle maintenance issues, fuel quality problems, poor combustion of the air-fuel mixture, engine intake issues, turbocharging problems, exhaust system faults, and anti-theft system failures are the main causes of the engine warning light illuminating. Additionally, during vehicle startup, the system performs a self-check on the engine. Normally, the warning light should turn off after the self-check is completed. If it remains on for an extended period, it is advisable to seek professional assistance at a service station to diagnose and eliminate potential safety hazards. Below is a detailed explanation of each potential issue: Sensor Issues: Sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors can cause the engine warning light to illuminate if they are damaged, have poor connections, or lose signal. In such cases, the ECU cannot accurately obtain engine data, prompting the warning light. Immediate professional inspection is recommended to address safety concerns. Maintenance Issues: Poor engine maintenance is one of the most common reasons for the engine warning light to turn on. Vehicles have specific maintenance schedules, and neglecting them, combined with poor driving habits, can increase engine strain, eventually triggering the warning light. Fuel Quality Issues: This refers to both fuel and engine oil. Vehicles require specific fuel grades, and engine oil can be semi-synthetic or fully synthetic. Manufacturers usually recommend the appropriate fuel grade and oil type. Failure to adhere to these recommendations can lead to engine wear over time, causing the warning light to illuminate. Always use the recommended fuel and engine oil. Poor Combustion of Air-Fuel Mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can lead to poor combustion. This results in engine carbon buildup or knocking, which the oxygen sensor detects and reports to the ECU, triggering the warning light. Intake Issues: The air filter plays a critical role in engine combustion. A dirty or clogged air filter can restrict airflow, leading to potential engine issues and the illumination of the warning light if left unaddressed. Turbocharging Issues: Problems with the intake turbocharging system or turbocharger can cause the engine warning light to turn on. Common issues include turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust System Issues: Faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings can trigger the warning light. The catalytic converter is particularly prone to failure due to the use of leaded fuel, improper oil additives, physical damage, or fuel system malfunctions. Anti-Theft System: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller is incompatible with the engine ECU, the engine may not operate correctly, and the warning light may illuminate. Solutions for Engine Warning Light Illumination: If the engine warning light is on and the vehicle cannot start, this may indicate a fuel pump or ignition component failure. Immediate professional assistance is recommended. If the warning light is on and the vehicle exhibits severe shaking or loss of power, pull over safely and call for roadside assistance. If the warning light is on but the vehicle operates normally, it may indicate a sensor issue. While you can continue driving, it is advisable to proceed at moderate speeds and visit a repair shop to diagnose the issue.

Does idling the Envision for 2 hours before shutting it off have any impact?

Idling the Envision for 2 hours before shutting it off does have an impact. Frequent idling can affect performance and cause certain damage to the engine. When the car is in an idling state, the engine continues to run, leading to incomplete combustion of fuel inside the engine, which generates a lot of carbon deposits. In low-temperature conditions, the engine produces even more carbon deposits. The Envision is positioned as a midsize SUV and comes in six models, each available in both National V and National VI emission standards. The Envision's body dimensions are 4686mm in length, 1839mm in width, and 1660mm in height, with a wheelbase of 2750mm.
