汽車故障碼大全

汽車故障碼大全汽車故障碼是汽車電腦（ECU）對(duì)汽車運(yùn)行狀況進(jìn)行診斷后，以代碼形式存儲(chǔ)的故障信息。這些代碼可以幫助維修人員快速準(zhǔn)確地找到故障原因，并進(jìn)行相應(yīng)的維修。故障碼通常由五個(gè)字符組成，前三個(gè)字符代表故障類型，后兩個(gè)字符代表具體的故障部件或傳感器。例如，P0300代表隨機(jī)/多缸失火，P0420代表催化轉(zhuǎn)化器效率低。P0000P0099:燃油系統(tǒng)故障P0100P0199:進(jìn)氣/排氣系統(tǒng)故障P0200P0299:點(diǎn)火系統(tǒng)故障P0300P0399:發(fā)動(dòng)機(jī)失火故障P0400P0499:排氣系統(tǒng)故障P0500P0599:車輛速度和怠速控制系統(tǒng)故障P0600P0699:ECU/PCM/TCM內(nèi)部故障P0700P0899:變速器故障P0900P0999:車輛動(dòng)態(tài)控制系統(tǒng)故障P1000P1099:網(wǎng)絡(luò)通信故障P1100P1199:制冷系統(tǒng)故障P1200P1299:空調(diào)系統(tǒng)故障P1300P1399:蓄電池故障P1400P1499:氧傳感器故障P1500P1599:進(jìn)氣壓力傳感器故障P1600P1699:節(jié)氣門位置傳感器故障P1700P1799:曲軸位置傳感器故障P1800P1899:凸輪軸位置傳感器故障P1900P1999:發(fā)動(dòng)機(jī)冷卻系統(tǒng)故障P2000P2099:EGR系統(tǒng)故障P2100P2199:燃油噴射系統(tǒng)故障P2200P2299:點(diǎn)火提前角故障P2300P2399:燃油噴射器故障P2400P2499:EVAP系統(tǒng)故障P2500P2599:車輛穩(wěn)定控制系統(tǒng)故障P2600P2699:發(fā)動(dòng)機(jī)控制模塊故障P2700P2799:自動(dòng)變速器故障P2800P2899:變速器離合器故障P2900P2999:變速器油壓故障P3000P3099:發(fā)動(dòng)機(jī)機(jī)械故障P3100P3199:發(fā)動(dòng)機(jī)排放故障P3200P3299:發(fā)動(dòng)機(jī)控制模塊故障P3300P3399:發(fā)動(dòng)機(jī)冷卻系統(tǒng)故障P3400P3499:發(fā)動(dòng)機(jī)潤滑系統(tǒng)故障P3500P3599:發(fā)動(dòng)機(jī)點(diǎn)火系統(tǒng)故障P3600P3699:發(fā)動(dòng)機(jī)燃油系統(tǒng)故障P3700P3799:發(fā)動(dòng)機(jī)進(jìn)氣系統(tǒng)故障P3800P3899:發(fā)動(dòng)機(jī)排氣系統(tǒng)故障P3900P3999:發(fā)動(dòng)機(jī)控制系統(tǒng)故障P4000P4999:傳動(dòng)系統(tǒng)故障P5000P5999:車輛動(dòng)態(tài)控制系統(tǒng)故障P6000P6999:車輛網(wǎng)絡(luò)通信故障P7000P7
