sensors advice

[dumhuve]

Hi! just joined. I have a -98 disco 1 and was reluctant to buy it back in -01 but
my wife loved it soo... and over 8 years later it's been a very good vehicle for us.
It still has a very solid feel at 140k, something that a jeep or explorer probably
wouldn't have.
Now, the engine and abs lights are on and according to shop diagn.
it needs both "downstream oxygen sensors" @ $ 790,00 plus tax installed.
Problem 2 is that it needs right front abs sensor @ 650,00 plus tax installed.
the brake/brakes do "tap" occassionly.

I've seen aftermarket sensors online and I would like to get them wire socket ready. I got moderate skills. Thank's for any advice!!

I replaced my o2's 3 years ago with NTK's @ $42ea.
The wiring color code was the same, I just cut my old connectors off, and soldered on the new - job done in a couple of hrs. (I didn't hurry)

Your abs sensor malfunction may be an unseated sensor.
tap in to re-seat.

I suggest a free download of the repair cd - search "free rave cd"

It covers more than you need for LR repair.

luck,greg

I agree with Greg, buy aftermarket as solder them in... or you can buy new. They are only $130 each new http://www.roverparts.com/Parts/AMR6244.cfm

ABS Sensors...

Fronts http://www.roverparts.com/Parts/STC1749.cfm

Rears http://www.roverparts.com/Parts/STC1750.cfm

But my 97 hasn't had working ABS in 7 or my 8 years of ownership... I feel safer this way (I do off road a bit) ABS and off road are not fun.

Thank's for the advice guys. I'm about to degrease the engine compartment as well
as underneath and have a closer look, maybe paint thinner will cut all that grease, ha ha.
Are there 2 or 4 O2 sensors btw?

 

[greg409]

It will have (4) - (2) ea side - (1) b/4 & (1) after ea cat

I just checked - the ntk's I bought were now $88 - the p&p were $100+ as joey said.

I'd do the p&p

luck,greg

When the shop diagnos says downstream sensors I suppose they refere to
the rear ones. Do they take metric and what size btw? I got slight surface rust even
in CA. I sprayed wd40 but they do seem pretty stuck. Are the sensors the exactly
the same for front and rear?

 

[joey]

on your 98 both sensors are the same... the rears just tell you if the cats are working.

I am pretty sure they are the small metric ones... basically 2 major sizes of heads on O2 sensors... LR use the small ones.

 

[greg409]

Yeah they're tight, when reinstalling you might smear A SMALL DAB of antiseize on threads

don't get any on sensor area.

luck,greg

A friend of mine is the editor for a 4 wheel mag in sweden and he said that
it's good to have the exaust hot while trying to loosen, hm make sense I guess
but I never would have thougt of it.

Just an FYI, NTK is a division of NGK (or vice versa) and are OEM for Land Rover.
