What is the fault code of 0546, how to eliminate it, and how to eliminate it?

P0546 Fault Code, applicable to all car manufacturers, means Exhaust Gas Temperature Sensor Circuit High (Bank 1, Sensor 1). Background: The function of the exhaust gas temperature sensor is to transmit the exhaust gas temperature to the electronic control unit (ECU) in the form of an electrical signal.

The correct air-fuel ratio produces a lower exhaust temperature than the exhaust gas produced by an over-concentrated or over-lean air-fuel ratio. Excessively high exhaust temperatures (> 160 degrees Celsius) can cause damage to the engine. This fault code appears if the electronic control unit (ECU) detects that the exhaust temperature sensor signal voltage is higher than volts (possibly volts) for a set period of time (15 seconds).

Fault codes can also be cleared by using a special instrument.

Fault codes are generally stored in random memory, and the status of each memory cell is recorded by the ECU according to the diagnosis and maintained by the system power supply. Therefore, when the engine ignition is turned off, power is still provided to the control unit to keep these storage units in working condition.

If the power supply to the memory of the control unit is cut off, the state of each memory will change to the initial value for a short period of time, and the degree failure information in the memory will no longer exist. Therefore, the basic way to clear the fault code is to cut off the power supply to the electronic control unit.

Hello! Fault code 0446 Fault system scope: emission control.

Uncover the bending method to raise the boring side: 1Cause of failure a).

Check that the fuel tank cap is not broken or closed poorly b).Check the EVAP system pipes for leaks and other faults c).Whether the canister control solenoid valve and its wiring are faulty d).

Whether the ventilation solenoid valve and its wiring have a noisy rubber barrier e).Whether the fuel tank pressure sensor and its wiring are faulty f).Whether the inlet pressure sensor and its wiring are faulty g).

Whether the ECU is faulty 2Treatment a).Check the fuel tank cap for broken or poorly closed caps, and if so, repair or replace them

Hello, I am very happy to answer for you, 52024324 fault code handling method is as follows: high-pressure part or fuel injector problem, check whether the high-voltage line falls off, the fuel injection early ear nozzle is blocked or damaged, gasoline land noise machine nozzle is part of the gasoline electric control system, replacing the carburetor of the carburetor type gasoline engine. The main nozzles used in automobiles are:

Diesel bump with oil nozzles, gasoline nozzles, natural gas nozzles, etc., now some foreign manufacturers can manufacture special nozzles for hydrogen.

1.Oil pressure indicator: This light is the oil alarm light, if the light is always on, it means that the oil stock and pressure are lower than the standard value ,..

2.Brake system fault light: When this light is on, first check whether the hand dust brake is completely released, and if the light is still on after releasing the hand brake, ,..

3.Power Steering Warning Light: This light is on to indicate a problem with the power steering system, which may cause the vertical power assist to weaken or disappear ,..

5.Tire Pressure Warning Light: This light is used to show the condition of the tire pressure, if it is normal, this light is off, and vice versa, ,..

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can be consulted at any time to ask the car to ask the question, 24 hours ** answer.
