确实是大部分情况是这个SENSOR坏了,但我也见过几次是CAM SENSOR坏的。你最好检查确认一下再说,不是已经 ...
今天去车场扫描了
trouble code
p0170 fuel trim (bank 1) -malfunction
修车的说故障范围很广,
啥毛病啊?
After googeling these results they came up with the following.
take the o2 sensor out and give it a clean with petrol (soak well, clean and let dry well). See if that solves the issue.
Look at the vacuum lines in the engine bay, 1 might of come off or is crushed and that will cause that code as well.
.
for the fuel trim codes, check there is nothing crushing the vacuum hose running from the throttle body to the fuel pressure regulator, that was my issue with mine.
need to pull maf out and give it a good clean then make sure its dry before putting it back in.
the other issue is as chris said, due to the gear selector
sit under the battery, just needs to be cleaned out as it builds up with gunk
changed the fuel filter
