Title: Code P1151 on a 24V
Post by Pegasus on Sep 24^th, 2006, 5:40pm

Hi,
just done a scan for hiacekim's 24V at the Kent meet today:

Got Code P1151 and scan shows upstream cat sensor on bank 2 is flat. Enhanced also gives the result of sensor failure detected (O2S21-FL).
The obvious is replace sensor or is there something simpler that can be done?

Also, LTFTs ~-14%, STFT on bank 2 goes up to 32% (lean) :o

Bank 1 cat, MAF, TPS, etc look fine.

Zipped file available if anyone wants to see it

Cheers

Paul

hi there

the ltft might be down to the fuel pressure regulator.

see this (http://www.fordscorpio.co.uk/fuelreg.htm)

Sad to see you're selling it though :(

All the best
