1. 17522 P1114 Bank1-Sensor2 Internal Resistant too High

2. 16524 P0140 O2 Sensor Circ.,Bank1-Sensor2 No Activity Detected

3. 17608 P1200 Boost Pressure Control Valve Mechanical Malfunction

I am getting these recurring fault codes in my Mk1 Octy VRS. Can anyone help me with this.

I haven't noticed any adverse affects to the performance with this. :confused:

Its an 03 VRS. Has been Stage 2 remapped by Jabba to 246bhp. Boost controller, Bailey DV30 dump valve, stainless exhaust, silicone hoses, air filter and relocation.

Having done a bit of research on here I have found these answers if anyone can confirm them for me??

1. 17522 P114 = heater gone in Lamda sensor 2 post cat to fix = replace

2. 16524 P0140 = Problem with abs to fix = ??? Anyone?

3. 17608 P1200 = Problem with DV or N249/N75 valve to fix = clean and regrease DV and/or replace N249/N75 valves

Hope someone on here can help before I have to bite the bullet and go to the stealers.:thumbdwn:

Cheers:thumbup:

Addition after research

1 & 2 both relate to the same O2 sensor, replacing it would be advisable.

It looks as though you are thinking along the correct lines.
