P1131 & P1151 FIXED! Cracked PCV Hose Causing Lean Codes on My 2002 Mustang GT

Check Engine Light? P1131 and P1151 codes on your Ford Mustang? In this video, I walk through my diagnostic process on my 2002 Ford Mustang GT Convertible and show how I found and repaired the problem. Using a simple OBD2 scanner, I pulled codes P1131 and P1151, which indicated a lean condition on both banks of the engine. Instead of immediately replacing oxygen sensors or fuel system components, I inspected the intake and vacuum system and discovered a cracked and collapsed PCV valve hose creating a vacuum leak. In this video you'll see: • How to read P1131 and P1151 trouble codes • Common causes of lean-condition codes • How to inspect for vacuum leaks • How to identify a failed PCV valve hose • PCV valve replacement on a 2002 Mustang GT • PCV hose replacement • Clearing check engine codes with an OBD2 scanner • Test drive and repair verification Vehicle: 2002 Ford Mustang GT Convertible 4.6L SOHC V8 Parts Used: • PCV Valve (EV-257) • Dorman PCV Hose (46080) If your Mustang has a rough idle, hissing noise, vacuum leak, or check engine light with P1131 and P1151 codes, this repair may help solve your problem.
