P 1 12e p0000 What does the fault code mean?
P 1 12E:
1, Chinese definition
Manifold absolute pressure (MAP) sensor-throttle angle is too low; ?
2. English definition
MAP sensor-throttle angle is too low; ?
Step 3: Types
Power system (customized by manufacturer)
4. reasons
The manifold absolute pressure (MAP) sensor is used to measure the pressure (vacuum degree) in the intake manifold. The powertrain control module (PCM) will then determine the basic fuel injection quantity of the injector based on the difference between the intake manifold pressure and the atmospheric pressure (which is linearly related to the engine load), thus helping the engine to achieve the best air-fuel ratio under different loads.
Extended data:
1. Use tools correctly
When assembling and disassembling assemblies, parts, connecting bolts and various shafts, bearings, gears, etc. , use the appropriate tools. It is not allowed to pick with a chisel or cut with electric welding or gas welding, and it is not allowed to beat with a live wrench instead of a hammer. If it is necessary to strike with a hammer, a soft metal punch or pad should be placed to prevent damage to the parts or matrix.
When disassembling parts, avoid damaging the working surface of the parts. Parts that can be disassembled and assembled with tension and compression tools should be used, and no hard hitting or knocking is allowed.
2. When disassembling components or parts, they should be marked.
When disassembling the assembly and parts, check whether the coupling parts, rotating parts and parts that cannot be interchanged have assembly marks before disassembling, and if not, re-mark them (such as marking the installation position of tires and rims of high-speed vehicles) to prevent the original matching or balance state from being destroyed due to wrong assembly. As the saying goes, repairmen are not afraid of missing parts for a long time, and they are afraid of forgetting how to assemble them.
If installation direction is required, look at the original direction or mark it to prevent reverse installation. Such as piston, cylinder gasket, connecting rod, etc. Marking papers is very important.
