1. What is the troubleshooting method for Tiguan fault code p2187?

[Pacific Automotive Network] The troubleshooting method for Tiguan fault code p2187 is to first check whether there is any air leakage and whether the carbon canister solenoid valve is always open; Recheck the data flow that affects fuel injection quantity, water temperature, intake flow temperature, battery voltage, etc., and troubleshoot each one one. The fault code P2187 displayed by Tiguan is due to air leakage in the intake system, insufficient fuel pressure, poor operation of a certain cylinder, inaccurate data from the air flow meter, damaged fuel injectors, and poor operation of the ignition system. From the meaning of fault code P2187, it appears that the system is too lean at idle speed. This should rule out the possibility of the mixture not being too lean at non idle speeds, which can be caused by either too little oil or too much gas. Firstly, assuming that it is caused by excessive fuel supply, noise and wear, if the fuel supply is too low in idle state before collision, then in acceleration state, due to the increase in air flow speed and intake volume, there should be a tendency for the lean mixture to collapse. However, the control unit did not record the lean mixture fault in non idle state. After troubleshooting the car, it is necessary to clear the fault code. When clearing fault codes, it is necessary to follow the clearing method specified for the corresponding vehicle model, and it is not allowed to use the method of removing the negative terminal of the battery to clear the car fault code at will. Otherwise, it may cause trouble in two aspects: firstly, it may cause the control computer of some car models to lose "experi

ence memory". I believe everyone knows that many car models have automatic memory function. After easily removing the grounding wire of the negative terminal of the battery, it will automatically clear the experience data stored in the random access memory (RAM) of the engine operation, resulting in poor performance of the car for a considerable period of time after maintenance, and may also have processed fault codes after driving for a short time; Secondly, it can also cause the loss of certain functions, such as frequently losing the audio lock function. In this case, in order for the audio system to function properly, it is necessary to repair the audio system again. This situation can be very troublesome.

2. The fuel consumption of the Tiguan has significantly decreased after maintenance

The fuel consumption of the Tiguan has significantly decreased after maintenance, which is usually directly related to the following key maintenance items or adjustments: engine system maintenance, ignition system replacement: If spark plugs, high-voltage packs or ignition coils are replaced during maintenance, the ignition efficiency will be improved, and the fuel combustion will be more complete, resulting in a natural decrease in fuel consumption.

. For example, when the original spark plug accumulates carbon severely, ignition delay can lead to an increase in fuel injection quantity. Cleaning/replacement of fuel injectors: Blocked fuel injectors have poor atomization effect. After maintenance, the fuel injection amount is precisely controlled to avoid fuel waste. Repair of oxygen sensors or air leakage flow meters: Malfunctions of these sensors can ca
