Power Steering Sensor error

[daljames]

Hi all, just got my 206cc back from getting the gearbox rebuilt and hooked up PP2000 to get any codes. The steering gets very heavy toward lock and PP2000 says 'Permanent; power steering sensor error'. Any ideas where this sensor is located?

Had 2 other errors. Miss fire number 4 cylinder intermittant and undetermined other cylinder miss fire.

Do get a little stumble at idle every now and again. New plugs, no change. Guessing coil pack?

Thanks to all respondents in advance!!

ps, will post pics soon!
