This code will trigger the check engine light as follows:The adaptive fuel strategy in the vehicle's computer constantly monitors the fuel delivery system https://www.engine-light-help.com/P0171-check-engine-light.html to make sure the engine is running at an optimum air to http://mechanics.stackexchange.com/questions/8758/check-engine-code-p0171-system-too-lean-is-it-safe-to-drive fuel ratio, which is 14.7:1. The computer adjusts injector pulse width to regulate the amount of fuel going into the engine. The oxygen sensors relay information to the Powertrain Control Module (computer), informing it of the oxygen content in the exhaust. This information is translated by the computer, and used to check engine determine if more or less fuel is needed. The computer will then adjust fuel flow (and possibly other related engine operating characteristics), to keep the correct air fuel mixture. This loop continues as long as the engine is running. Please refer to our article Oxygen Sensor Code Diagnosis for more info on this system. A P0171 check engine light code is set when check engine code the computer has reached a rich calibration limit and can not add enough fuel to maintain the correct mixture.

I read the codes using an OBD code reader and got P0171 - System Too Lean (Bank 1) and P0133 - 02 Circuit Slow Response (Bank 1, Sensor 1). The light is on solid, not blinking. From what I can research online this seems like the most probable causes are the intake gaskets needing to be replaced or needing a new Mass Airflow Sensor. Though I haven't done any smoke diagnostics so I can't rule out another cause. My question is: is it okay to drive my car while it shows these codes? I don't want to do permanent damage running too lean. If I drive to the mechanic's or to pick up parts will this cause issues? Or should I get it towed? obd-ii cel p0171 p0133 share|improve this question edited Feb 12 '14 at 6:20 asked Feb 11 '14 at 15:04 culix 137118 Those codes should probably be P0171 and P0133. –Pᴀᴜʟsᴛᴇʀ2 Feb 11 '14 at 16:48 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted This should not cause you an issue, but this sounds more like a problem with the O2 sensors than with the intake gaskets. When was the last time you had them changed? If you are over 100k miles without new ones, I'd highly suggest this first. One way to check your theory for the intake gasket is by using a spray bottle with water (on jet, not spray). With the engine running at normal operating temps, spray the area of the intake manifold gasket. You are wanting to hear a change in tone of how the engine is running. When you find a hole (or leaking area), there will be a distinct difference in how the engine runs. The O2 response being slow is what is inclining me to think of this. As O2 sensors get older, the don't normally go bad per-se, but rather they get lazy. They will continue to get more l
