Teana 13 2.0 shows that the fuel pump pressure is too high.

Teana 65438+2.0 in 2003 shows that the reason of high fuel pump pressure is insufficient pressure. According to relevant data, the reason why the degree of high-pressure fuel pump is too high is that the air and intake pressure in the engine cylinder are insufficient, resulting in incomplete fuel combustion in the cylinder. Common problems include dirty throttle and intake air, carbon deposit, three-way catalyst blockage, carbon deposit in spark plug, oxygen sensor and other component problems.
