Malibu :: 2010 - CEL Light Came On / Error Code P0172
Aug 11, 2013
As the title says it all I have a 2010 Malibu LS with roughly 88k on it and just noticed that the CEL light came on last weekend. On Monday the light went ahead but it came back on this morning. Took it to Autozone and the error code was P0172, Fuel System Too Rich, Bank 1. I noticed this happened last weekend after putting in some gas at QT. The Autozone guy recommended some fuel injector cleaner as a starting point and recommended using pure gasoline (premium).

I have a Toyota Prius (2010), and the car has run for about 2800000 kilometers. One day when a was driving my Prius the engine light suddenly get on. So I went to a car car mechanic, he checked the car and told me there was an error code (error code: P0401, exhaust problem (exhaust recirculation flow).
So I bought a liquid that I put in the gas tank, the liquid would clean the exhaust pipe, but the engine light was still on. The engine light is usually on at least 2 weeks, then disappear for about 2 days and come back in two weeks…The car is driving normally without any problems.

My girlfriend drives an 09 corolla (1.8L I believe). I have an OBDII bluetooth reader w/ Torque App so to identify the issue I can get some data:
Last week I was driving the corolla and I got P0031: HO2S Heater Control Circuit Low (Bank 1 Sensor 1). Car seemed to run fine without any issues. My girlfriend brought her car in to her "mechanic". "mechanic" who will replace have of your engine only to realize that your gas cap was cracked. He apparently replaced 02 Bank 1 Sensor 2 (I'm still trying to confirm this and to get the part # to make sure). He reset the ECU and she drove for about 30 miles after which these codes popped up:
P0172: System too Rich (Bank 1)
P0101: Mass or Volume Air Flow Circuit Range/Performance Problem
The car was idling rough. I reset the codes and the car was running fine until all monitor systems were ready. When Catalyst, 02 Heater & 02 Sensor are not ready everything is running fine and I don't see any error codes. I cleared ECU a few times. The last time I was able to drive for over 20 miles without any issues. Currently the only sensor not ready is 02 and car is running fine but I have a feeling once its ready the car will start having issues again:
Summary (if you don't want to read everything)
*P0031: H02S Heater Control Circuit Low (Bank 1 Sensor 1) - Car runs fine
*Mechanic replaces 02 Bank 1 Sensor 2 (Trying to find part # and double check sensor name)
*ECU reset and car runs fine for 30 miles
*P0172: System too Rich (Bank 1) and P0101: Mass or Volume Air Flow Circuit Range/Performance Problem
*ECU reset - car sputters and hesitates
*When all monitors are ready same codes (P0172 & P0101)

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

I have a 4 door 1.8t AWW
Like I said in the title I keep getting the P0172 and can't seem to shake it no matter what I do. I believe the car is in soft limp mode as I can't boost above 5 psi. I'm also consuming oil fairly quickly (atlas 2 quarts in a span of 2-3 months), no smoke out back though. I did find that the whole PCV system underneath the plenum was wet, but nothing else was? Checked the PCV valve and it seemed operational and didn't stay open. Check PCV system for cracks and was unable to see any which added to the confusion.
Thing's I've done to try and fix problem:
-replaced breather hose because of crack
-went through all the vacuum lines and replaced where needed
-have two n75j's that I'm unsure if they work or not (is n75j the stock valve for the AWW?)
-cleaned the maf
-replaced valve cover gasket
-changed plugs
-replaced dv with splitter
Other things for diagnose:
-little wet around 2 of the injectors on top of the plenum (old o rings?)
-when running splitter full atmospheric I can hit 10psi but with it closed off can't get past 5psi

I have a 2003 Ford Taurus. It has been running rough for awhile. It doesn't happen all the time, alas. I took it to my local repair guy. They first said, oh this happens when the AC is on. But I knew it happened otherwise.
The check engine light came on yesterday, blinking, but didn't stay on. And it was running rough. Check engine light came on, on a Sunday so I had to wait until Monday to bring the car in. They just called and said they can't find anything wrong, ran it on the computer, says it's running fine. I said, did you check the spark plugs, wires, etc? (I am good at googling, to be armed with some kind of info)
I am thinking they just put it on the computer. I suppose it has to be running bad to show anything (?) and even then, it's no guarantee. Anyway. It seems like I am "sentenced" to driving this car until it strands me, catches on fire (I read about that possibility and I have on occasion smelled something burning), or if luck has it, when it is running rough, and I bring it in while it's running rough, the computer finds the problem.

So my truck is reading a code at P0172 which means bank one is too rich. I replaced all of my o2 sensors, cleaned my MAF, and replaced PCV and hoses connected to it. What else could it be?

I have a 2005 F150 Fx4 5.4 that keeps throwing a p0172 code. I've replaced all spark plugs, C.O.P's, fuel injectors, Mass airflow sensor, 1 o2 sensor, checked all vac lines and there ok.

Having some idling issues. Pulled codes P0172 and P0304. Basically running rich on fuel bank 1 and misfire on cylinder number 4. My question is what is the locations of each...? From what I have read number 4 cylinder is closest to the drivers side and fuel bank 1 is on the passengers side. I have changed the MAF, plugs and checked the ignition coils. All looks to be good. I am guessing possibly fuel injector?

I had to change my fog light fuse tonight, no reason found for that. However, I somehow triggered an error code, P01C1. I managed to reset it, but what this code means?

I have a trouble with my 2008 prius; red triangle engine light is coming and when i try to push the gas pedal it feels like it's freeze, the car does not accelerate so I have to stop.
After i turn it off and start again it drives ok, but a triangle is still there and there is error code POA90 ( two different scanners show same code with two descriptions; the first is "MOTOR PERFORMANCE"; the second describe it as "14-volt power module system voltage high").
Specially it happens when i drive up the hill and push the gas pedal harder. What it can be? I took the car to the Toyota dealer; they looked for 8 hours and find nothing; i can't do it again as the car do not have a warranty and the dealer charge for hours.

I am trying to determine the P106 error message (MAP sensor, or 5V error). Where the MAP sensor is located as well as what else I should be looking at? Something else that has been odd is when the ECS error comes on the check engine comes up as well. I just had my car in for the ECS, brake light recall with no change.

What may be the issue with my truck. Drove earlier in the day and hauled trailer. Ran fine. Got it home and once I unloaded trailer and went to start up truck again it died a minute into backing up. I tried to restart and turns over but dies in 3-5 seconds. Tried again a few hours later and next morning and same thing.
Pulled code and came up P0172- Bank 1 running rich. I had replaced the Mass Air Flow sensor a few months ago. Since it was still under warranty I went and got a new one in case that was the issue, but didn't fix. When I try to start it smells like gas. Sounds like fuel pump is coming on fine. Checked air filter.
Of course is still hooked up to the trailer and in a tight spot in the yard at the moment so anything basic/inexpensive I can try myself first would be great.

Bought my 2010 Prius with some issues, most of which are now fixed.
The remaining issue is the mentioned A/C error code: B1498 A/C Communication malfunction (A/C inverter local)
What part this is, and the OEM part number? Where is it located in the car?
Previous owner claimed it was some error with the A/C Control unit.

So got this P0A93 code when I was driving on the highway about 65mph, scared to me death when big yellow warning light came on so I returned home and turn the car back on after 30 mins the code and all the warning lights were gone I checked under the hood felt the pump everything was good. I just got done 90k maintance on the car from dealer. So my question is that could be computer error or it could be water pump malfunction? On warranty manual the warranty for inverter with converter covers under 100k so dealer should be able to cover the water pump if it's broken? I driven the car today again at normal temperature and full blast AC on, then again no engine check light on and warning light no message.

So I changed my spark plugs, due to an error code saying p0301 which means cylinder one misfiring. I reset the engine light disconnecting the negative battery terminal. Once it reset it ran rough for a few miles. I put about 50 miles on it and it seems better.

I was cruising down the highway and my check engine light came on. I was a few minutes from a auto store and they said my code was p1296. I found out it is either the thermostat or the coolant temperature sensor. I wanna know where it is located in the engine bay. I have a 02 VW Jetta 1.8T.
