Due to the large number of possible causes of P0170, it is recommended that all other codes present be diagnosed and repaired before attempting to repair P0170 to avoid a misdiagnosis. If that has not happened then you may have a vacuum leak. Bank 1 refers to the bank of cylinders that contains cylinder 1. Can't believe how bad it was running before. The same thing applies for rich conditions, with factors like a faulty airflow sensor manifold, faulty fuel pressure regulator, and absolute pressure sensor. When does the oxygen sensor actually come into play? Is there anything i can add in gas to remove moisture or water from presure regulator? My fuel mileage has dropped to low 20s a gallon. They were nice enough to check the car again and found some kinfd of vacuum tube was not connected.
If you have any doubt as to repairs on your vehicle, please contact your technician. This would help to explain the low idle when coming to a stop. Went to Midas, where i had got my oil chnag done. Look for damaged, burnt, broken, shorted, or corroded wiring and connectors. For me it was the bank 1 O2 sensor.

After the repairs are made, the mechanic would reset the Check Engine Light and run the engine. If damaged fuel lines are found, resist the temptation to repair the lines. The powertrain control module receives a signal from the oxygen sensors and will adjust the amount of fuel the engine receives based on the readings provided by the oxygen sensors. I cant afford to throw money at it and can do most of the work myself if I could get some idea of the problem. I need help please help me.
This code by itself causes no symptoms whatsoever, but in conjunction with other conditions, it may eventually lead to a large array of drivability issues. The car runs great, but when you first start out when the engine is cold the car wants to stall when you give it gas. The currently selected is for the Honda makes. Any help would be greatly appreciated!!! Also check ignition coils, cam and crank sensors, and oil sensor for leakage contributing to oil intrusion in wiring harness. Leaking turbo pressure hoses could cause a rich condition.
So I changed the fuel filter, sparkplugs, wire. Now it is summer it does not do that now I have new problem I just started getting this code P0170 and P0171. Moisture would be purged back to the fuel tank via the pressure regulator so you don't worry about that. This may include repairing rich or lean engine issues before moving forward. It been four days still no code so hopefully that will fix that problem. Expect to see at idle 3. For American cars, the most common fuel trim error codes are P0171, P0174, P0172, P0175, which refer to fuel trim malfunctions.
Such codes must be resolved before diagnosing code P0170. Perform a thorough visual inspection of the entire fuel system, and check for damaged, kinked, pinched, or otherwise damaged fuel lines that could restrict the flow of fuel, since the volume of fuel that is delivered to the engine is as important as the pressure it is delivered at. I was reading about how to cleaning throttle body but then saw this Tip 1: Don't Do It! If the driver experiences drivability issues they may decide to repair the vehicle sooner to avoid future problems. Code P0171 indicates that a lean fuel condition has been detected, which could be a result of a bad , a clogged fuel filter, a dirty or faulty , a vacuum leak downstream of the mass air flow sensor, a faulty and many others. Even if it doesn't solve the problem it's not a bad idea as far as maintenance goes. Hello and thanks for writing in. Alright the problem with the reving up in down.
If any of you have tried all this stuff, particularly just cleaning out the easily accessible portions of the intake, I recommend a SeaFoam treatment because worse case scenario is you don't get a cheap fix. So I changed the fuel filter, sparkplugs, wire. Im a girl, so I'm thinking i was just told anything at the shop???? It may also have a P0173 Honda referring to the same malfunction but on bank two. My car has a manual transmission. Fixed it and reset the light.
Occasionally the light will go out for a couple of days and then its back on constantly, right from start up. Also, other conditions present can also affect the symptoms. If any other codes are found, they may be causing this code to occur. It is always important to have engine issues diagnosed by a certified mechanic who follows the correct diagnostic procedures. However, if the code does return, it is likely that the catalytic converter is at fault.
If the code P0170 comes back, then there must be another problem. I don't known where I started to do. Originally everyone said primary o2. Enter the 5 character trouble codes in the search box and submit the search. Can anyone point me in the right. If you've never done it before the best way to do it is as follows.
Also be aware that that the severity of one or more symptoms may differ between applications. Look up the other , please use the search box. The mechanic twice misdiagnosed light came back on ten minutes after i picked it up. Consult the manual for the ideal fuel pressure range for the application being worked on, and follow the procedure outlined in the manual to test the actual fuel pressure in the system with a dedicated fuel pressure gauge. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. Went to autozone and got the code read for free.
