306Xsi Lambda sensor

My lad has been told the lambda sensor has failed on his 1995 Xsi.
Anyone know if this a standard 4 wire sensor? Been quoted £95 from Pug
but there are some on Ebay for a hell of lot less. How easy is it to
replace this?

TIA

Mine went on my 1997 XSi last year. I got a new one from
http://www.lambdasensor.com/ It was a brand new sensor and it cost about
£45. I rang up and spoke to the guy, and he was helpful and ensured I
ordered the correct one for my Peugeot. I then paid a local garage £20 to
fit it as it's quite a fiddly job. I've had no problems as yet from it.

 

What were the symtoms when it went? He's not getting very good fuel
consumption and Pug dealer says the sensor has gone. Would this cause
high fuel use ?

I had the orange engine management light illuminated on the dashboard. I
flashed the code out using a Gunsons unit and it indicated lambda sensor
failure.
If the lambda sensor needs replacing the engine management light should be
light on the dashboard. Get proof from the peugeot dealer (be very careful
trusting what a peugeot dealer mechanic says), or better still go to an
independant garage and get the ecu unit code read. Sometimes just cleaning
them will give them another 6 months or so.

 

That's part of the problems he has, the management light comes on,
goes off for a while and then comes back on. So guess Pug were right
and the sensor has gone.
Thanks for the help and info.

cheers,

Mine used to go on and off as well. When it's on I'm led to believe that the
car will be in 'limp home mode'. basic engine management settings and poor
fuel effiency. Get it fixed as quickly as you can. I'd order a new lambda
sensor off the web or a decent car parts place other than a Peugeot dealer,
and either fit it yourself or get a decent garage you know to fit the new
sensor.

Good luck.

 

Thats the problem I have, getting 30 mpg with my 1.4 306 so its going to
garage for some diagnostics.

 

30mpg on what type of driving?

With our 1998 306 1.4l I get about 38-40mpg on a 400 mile round trip on
the motorway at 70-80mph. I think I can, on 90% motorway drives, push
up to 440 miles out of a tank before the light comes on (6 litres left I
think I read somewhere).

On a 75% round town, 25% 20 mile round trips style driving, I might get
360 - 375 miles out of a 50 litre fill up - so about 32 - 34mpg.

I've never considered these to be too bad, especially as I tend to be
quite hard on my acceleration etc. When our clutch was dodgy, my
driving style was more sedate and I believe our fuel efficiency
increased. I'd probably also do better driving at 60-70mph rather than
70-80mph.
