I have a 2003 Silverado 1500 with the 5.3 in it. For the past couple months the trucks been getting the p0172 and p0175 bank 1 and 2 running rich. I have clean the maf sensor and put a new air filter and spark plugs in and cleaned the pcv valve, throttlebody and map sensor too checked for leaks around the intake manifold and around the throttle body and found no leaks also put in new o2 sensors and the codes still come back up every time. Wondering if anyone else has had this problem or know what could be causing the codes? I’ll post a picture of the freeze frame data from the codes too.
In this video we show the step by step process for changing the high pressure fuel pump on Cliff's 2014 Silverado with the 5.3L EcoTec V8. This issue is related to fault codes Powertrain P0172 and Powertrain P0175. The exact issue is fuel being blown past the HP fuel pumps seals and into the crank case which contaminates the motor oil. If left uncorrected, this can damage internal components as the oil will break down due to the fuel and lose its lubricating ability. ?? LINKS TO PURCHASE TOOLS & PARTS FEATURED BELOW?? A quick indicator that the fuel pump is likely at fault is a smell of fu
My 2011 Sierra, 169K miles old, just started to stumble on cold starts about 2 weeks ago. Today I got the P0175 code. There's plenty of troubleshooting to do for that code and I'll start on it asap (it's cold in MI). This is the first issue I've had with the motor ever and am wondering if one event could be causing this. About 5 weeks ago I inadvertently filled up with 93 octane. That was the first time in 479 fuel fill ups that I've deviated from 87 octane. The motor has always started on the first turn whether with key or remote start since new. But in the past month it takes a couple of tu
I have a 2006 gmc Sierra 1500 with the flex fuel 5.3l vortec. A few weeks ago I had a check engine light turn on for p0175 (system to rich bank 2), the light turned off the next day. now about 2 weeks later it turned back on with p0172 (same code except it is bank 1). Any Idea why my truck is throwing these codes, or what it might take to repair it? Any help is appreciated, thanks.
