The Nissan code 0115 which converts to P0170 which is fuel system too lean, bank 2. The O2 sensor on that bank is very new because I got a code for that earlier. The car is running very rough and …
Can a bad O2 sensor cause a p0170?
A bad O2 sensor could cause a P0170, or P0173. Repair cause of oil leak and replace oil-fouled O2 sensor. Among several codes my car has, one is P0447 which is listed as EVAP emission system – vent control valve circuit open. No idea as to where to start checking as i am not sure if this car has a sensor in the fuel tank.
What does fault code p0172 and p0175 mean?
P0172/P0175 Diagnostic Theory for Shops and Technicians. When a vehicle has the fault code P0172 and or P0175, it means that computer can no longer automatically adjust the mixture between air and fuel. Code P0172 applies to Bank 1 and P0175 applies to Bank 2.
Is the p0172 fuel injection system too rich?
P0172 with P0175 or MAF DTCs – If you note both P0172 and P0175 or concurrent MAF-related DTCs, then you can likely rule out individual cylinder, ignition, and fuel injector problems. Instead, focus on the fuel injection system and the MAF.
What happens if your DTC p0172 goes into limp home mode?
Depending on the nature of the failure, DTC P0172 may or may not be accompanied by drivability issues. At the very least, you will experience poor fuel economy, because, with the ECU in “limp-home mode,” it is no longer looking at HO 2 S and AFR sensors for feedback.
Can a stuck fuel pressure regulator cause a rich condition?
A stuck Fuel Pressure Regulator can cause a rich condition since the Fuel Pressure will be too high, causing an “over fueling” condition. Be sure to verify proper Fuel Pressure under various driving conditions.
