Step 2 Refer to the manual to locate and identify all components correctly. To prevent the possibility of an engine fire, only start the engine once it is certain sure that the gauge is attached securely. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. The fuel level sender communicates fuel level by a float that sits on top of the fuel level. Make repairs or replace wiring as required to ensure that all electrical values fall within the ranges specified by the manufacturer. I'm sure you can dig up my old thread with the dyno runs.
The leak detection pump is part of the evaporative emissions system. This process works to reduce tailpipe emissions. YourMechanic offers certified mechanics who will come to your home or office to diagnose and repair your vehicle. So last year i purchased a used 2009 buick enclave cxl for my wife and i must say i have been very satisfied. I think computer is relearning the fuel trims because it feels a bit slower. Any help is greatly appreciated.
Jan 21, 2010 If you have the second ignition key's with you try it. The image below shows a Fuel Control Module that had failed because of corrosion of the metal casing. If it is certain that all wiring is free of faults and defects but the fuel pump will not start, refer to the manual on the correct procedure to follow to test the pump and the pressure it delivers with a current drawn directly from the battery. Looked through the search forums and it has a few of these codes but with several others listed that I do not have. Compare all obtained readings with the values stated in the manual, and repair or replace wiring as required to ensure that all electrical values fall within the ranges specified by the manufacturer. I was pretty low on ethanol and it's been cold, but I wasn't pushing the car hard at all and ran into issues.
I was very low on gas and I do believe ethanol doesn't flow as well at cold temps. Lol, well I wonder how much more power I could get with the high lobe cam with the tune. Anyone know what would cause these problems? After the drive cycle, the engine should be idling normally. An electric motor moves the gas through and pressurizes the fuel system. I was up there with the first few to get the E85 tune and, I'm leasing so no cam yet, still I wasn't pushing the car much.
So ran in to some bad issues while on the highway. It occurred intermittently but after I turned the steering wheel to the left. Look for damaged, burnt, shorted, disconnected, or corroded wiring and connectors, and make repairs or replace wiring as required. What are the common causes of code P069E? Step 3 If the engine starts and runs, locate the dedicated fuel pressure testing point; however, do not start the engine before attaching the fuel pressure gauge to this point. Jan 28, 2010 u followed the pin point tests for these codes you had? For this reason, this is considered a serious code and it is recommended to have it diagnosed and repaired as soon as possible. Just puttin around town feels different.
What Repairs can Fix the P2635 Code? No start, no fuel psi. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. I can command the fuel pump to prime with my scanner. Jul 27, 2012 The overdrive solenoid in the transmission locks the torque converter, and at low speeds, if it activates or hasn't released from a high enough speed, it will cause stalling. Maybe it's worth it to change. Scanned and i got p0191, p0161, and p069e with all seem to point to fuel delivery. Step 7 Note that on some applications, completing multiple drive cycles may be required before this code can be cleared.
It felt like the car was going to die. If no visible damage to wiring is found, perform resistance, reference voltage, ground, and continuity checks on all its associated wiring. It is important to take this code seriously and have it diagnosed and repaired as soon as possible. Does anyone know how to tell if my vehicle is equipped with it. Note that this code affects applications with electronically controlled returnless fuel systems, and that the types of faults that trigger this code are typically those that are likely to affect emissions.
I did come across something about engine mount vacuum for ride stability. Usually changing the fuel filter will give you some temporory improvement if this is the problem. Taking your vehicle to the dealer for service will keep you informed of what is going on with your vehicle. Step 1 Record all codes present, as well as all available freeze frame data. Note however that since returnless fuel systems do not have the ability to bleed off excess pressure, the system relies on very accurate data from the fuel pressure sensor in order to avoid both over-, and under fuelling conditions.
Look for damaged, burnt, shorted, disconnected, or corroded wiring and connectors, and make repairs or replace wiring as required. So next i got the fuel rail pressure sensor, replaced and what do you know performance issues went away however after a day of drive mil came back on and it is giving me same code. Using my google fu I'm getting varied reasons for the P069E code. I cranked the engine and sprayed some gas into the intake and it runs. In order to work effectively, the power control module must always know what the fuel pressure is. If you have any doubt as to repairs on your vehicle, please contact your technician.
