So checked the exhaust and no sign of any leakage. Have driven for 50 miles since clearing the codes and the eml hasn't come back on yet. When I do a scan only the ignition switch faults show.
Is it now a matter of waiting to see if they reappear or should I be more proactive? According to Ross tech the codes could mean;
18609/P2177/008567 - Bank 1; System Too Lean off Idle: Upper Limit Exceeded
Possible Symptoms
Malfunction Indicator Ligh (MIL) active
Possible Causes
Fuel Pump (G6) faulty
Mass Air Flow (MAF) Sensor (G70) faulty
Intake System leaking
Exhaust System leaking
Wrong Fuel Pressure Sensor (G247) on Fuel Rail
MAF sensor air flow disruption
Possible Solutions
Check Mass Air Flow (MAF) Sensor (G70)
Check Fuel Pump (G6)
Check Fuel Injectors
Check Intake System
Check Exhaust System
Confirm correct Fuel Pressure Sensor (G247) part number
Check Air Filter, air box, etc.. Air flow is disrupting MAF readings
And
17522/P1114 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
Possible Symptoms
MIL On
Possible Causes
Faulty O2 Sensor
Wiring Harness Issue for O2 Sensor
Possible Solutions
Inspect O2 Sensor and Wiring Harness. See Repair Manual
Any advice most welcome, thanks.
