On a C18XE..
Is this more likely to be a knack'd cat or O2 sensor?
o2 sensor id imagine! Is it a cheap aftermarket one in there?
Code 13 on the LET is Lambda sensor, dunno if its the same on yours...
My first thought was lambda, but I've had the voltage high/low code, never this one.
Haven't a clue what's in there tbh...
The reason I asked is because Kirsty thinks she can hear a noise from the cat (that 'fizzing' you get when the internals start to collapse, she says)..
and how exactly would the lambda sensor which detects oxygen in the exhaust manifold tell if the cat is ready to die? (especially when the cat is downsteam of the sensor)
thats like your engine ecu telling you uve got a bald tire
running with lambda open circuit will however make the engine run a bit richer than normal and this extra fuel will usually burn off inside the cat causing it to heat up and eventually (ie enough fuel) it will overheat and die
i doubt yours has got this far if the lights only been on a few days
and open circuit usually means a wiring fault so check the continuity of the wiring before touching the sensor
That's not exactly what I meant......Originally Posted by Aragorn
I'm fully aware that the ecu cannot detect a fubar cat, but codes don't always identify a specific, single issue...
We've had the eml coming up intermittently for a couple of months.
Ive got the same code comein up,,mines had a new lambda sensor on at some stage got wires electrical taped together 2ft up from the sensor itself,,,so do i need to change it (knackered) or does it have to be soldered together with it sayin open circuit?????
It's quite common for O2 sensor wires to be cut and joined when fitting a new one (I prefer to change the whole thing)...Given the comments up there ^^ I would check the condition of the join.... maybe solder the wires if possible?
Checked yesturday and looked ok,,,,,manegment lites been flashing on n off for last 3-4 days,,,,,,,,so solder them you say??? how much are they to buy new do? you no????
i buahgt a universal sensor when mine went and it came with bare wires an 3 butt connectors in the box so thats prolly what the tape is
if its been coming on intermittantly it could just be a duff sensor - 13 can actually mean any of open circuit, short circuit and out of range(or not moving) readings as far as i can tell as theres only one code relating to the lambda sensor
13 Oxygen sensor - open circuit
38 Oxygen circuit - voltage low (weak)
39 Oxygen circuit - voltage high (rich)
Slightly different for the XEV iirc.
As for cost..... I think car specific ones are about £80 depending on where you get them from.
We got one for the Senator from an online shop for a tad over £80...
im only getting 13 comein up,,,,its been doin it for a while now but its very regular now over the past few days,,,,,went for mot wednesday and failed emissions 1st time round but past the second so cant understand why im getting the code????
just got a new lambda sensor will let you know how i get on!!!!!
