Pip 12 Posted January 31, 2019 I bought a Yaris brand new back in 2005 for the wife. This has and still is the most reliable little runabout I’ve had. It’s never had any thing go wrong and it still has everything working properly. Now around 2 years ago it threw up the eml light but still runs perfectly and still flew through the last two mots. The code is showing cam shaft sensor. P0146; it use to be intermittent on for a day,off for 3 and so on. Now it is on permanent and when I reset it, it comes back on after 1 mile or less. The mot is due soon and I’m wondering if to reset it before mot to get it through or spend a fortune just to extinguish eml. As I said it runs perfectly and passes emissions test every year. I’m not going to sell this as it’s just an old runaround. It’s cheaper to go around the south to auctions in it rather than in any stock vehicles. just feel reluctant spending on my own and the sensor alone isn’t cheap. Shame as it’s not even on 60k yet.

NOACROSS 414 Posted January 31, 2019 Are you sure the chain hasn’t stretched. I had this on one a while back. 2 Share this post Link to post Share on other sites

Dave2302 387 Posted January 31, 2019 I can't see how changing a Cam sensor is going to cost you more than £20 ?????????????????????????? If it still pops the code after that then yeah, may be chain stretched, but that is more a Vauxhall and Nissan thing rather than Toyota Edit, Just priced Cam Sensor, 3 options, £17.00, £22.00 or £96.00, still hardly a fortune though, but i can't be more specific without Reg / VIN Share this post Link to post Share on other sites
Pip 12 Posted January 31, 2019 Must be the sensor. For this one it’s about £100 not too bad if it solves it. Just looked again all oil is like the day it went in, all waters are fine and just driven it 20 miles to the block and drives perfectly. Ticks over so quiet but will fail mot on eml Share this post Link to post Share on other sites
Nick M.K. 574 Posted January 31, 2019 Is VEMO OE? i always thought they were a budget brand of ECP... Share this post Link to post Share on other sites
It's me 615 Posted January 31, 2019 if it is due to chain lash and the sensor showed is the correct one then there is no point changing it as they work or they dont however they work by the whats called hall effect so if you broke off the fixing lugg and twisted it in its hole ever so slightly and fastened it up with a washer then the hall would be slightly out to the chain and thus the crank sensor to cam sensor would be more in time and the light would stay off just sayin.............. 1 Share this post Link to post Share on other sites
Dave2302 387 Posted January 31, 2019 You won't know if it's Chain Slack until you try a Sensor, especially as it isn't rattling. Like I said, slack is not such an issue on these as it is on Micras and Corsas etc. Shame yours is the dear one outta the 3, that VEMO is the wrong one if yours is the £97 one I dunno about you guys, but i don't fit cheapo sensors these days, too much Chinesium shit about, fair enough if it's an older car I'm not suggesting Main Stealers, but get a decent OEM one like a Bosch, Hitachi, Nippondenso, (I dunno who makes 'em for Toyota), but you get the picture Share this post Link to post Share on other sites

I have had Exedy and Valeo clutches in Japan Parts boxes , FAE sensors also Valet and Valeo thermostats when ordering the cheapest unknown, Lemforder power steering pump reboxed by Febi , Mercedes stamped parts from Febi etc Helps if your are not in a hurry I admit in case you get cheap tat occasionally. I always use Febi or Lemfoerder on my own MB's, they are the OEM for MB. Get a "First Line" Ball Joint for a Mercedes from your factor and compare it to the Febi / Lemfoerder Equivalent, you can see and feel the difference, that is why we (myself and a local fleet owner mate) no longer use "First Line" .................... Most of my Customers, and my own Cars will clap them out before the next MOT, yeah ok the factor will give us another, but you soon get tired of doing the same job several times over !! All the OEM parts I've ever fitted does stellar mileage, even the local 'Prawn' big Sprinters that get hammered and abused between Kyle of Lochalsh and Manchester every night of the week don't bugger up Febi Swivels, the First Line stuff was frightening, monthly vehicle checks and they would be fucked every other one, it was that that stopped us using them !!

KSMOTORS 1 Posted February 3, 2019 Have had Yaris's with the same fault and sadly turned out to be be timing chain stretch even though no symptoms except the EML on. Share this post Link to post Share on other sites
Dave2302 387 Posted February 4, 2019 /\ /\ /\ Yeah, but surely you agree with me that you gotta try a Cam Sensor first before you either bite the bullet and do a chain job, or sell it cheapo SOR ..................... One could always borrow a Cam Sensor off another Yaris from a friendly Trader / Mechanic workshop if you don't want to buy a £96 Sensor 1 Share this post Link to post Share on other sites

We find the Yaris great little things but have had them EML on due to chain stretch but still as quiet as a church mouse, then the other ones sounding like a threshing machine on full pelt at idle but no EML on!

BHM 994 Posted February 6, 2019 14yr old Yaris that he’s keeping? All I’d do is clear the code as I pulled up to the MOT station. Share this post Link to post Share on other sites
Dave2302 387 Posted February 6, 2019 I believe, (correct me if I'm wrong and I'll go look at the current Testers Manual), but an "Engine" Malfunction Lamp is only an MOT fail if the Emissions are also high, so it would Fail on "Emissions", and Advise "EML on" but a lot of Testers are a bit confused by all these lamps .................. SRS / ABS / Traction / TPMS / Brake Wear, Brake Fluid Level etc etc ................ Yes, definite fail .................. Safety Items !! EML is more complex than that, could be a minor sensor that has no bearing on Emissions or Safety HTH Share this post Link to post Share on other sites
BHM 994 Posted February 6, 2019 EML illuminated is an automatic fail. Unless the tester has grit in his eye & doesn’t see it Tbh does the E stand for Engine or Emissions? It depends upon which manufacturer’s manual you are reading. Share this post Link to post Share on other sites
Dave2302 387 Posted February 6, 2019 Hi, /\ /\ /\ yeah, you're quite correct, these days, (since last years rule changes), it is now an Automatic Fail, so my above post is bollox, please disregard, no milfs or small furry animals were harmed in the making etc etc etc Share this post Link to post Share on other sites
Scooby who 41 Posted February 6, 2019 I don't see the problem. Get a used sensor on eBay or from the breakers and if that doesn't fix it change the timing chain and sprockets. If it's the chain you'll know as it rattles like hell This is a two hr job at most, and really quiet straight forward. I've personally done many in the past and happen to have a new kit in a box I'll take £30 for. Easy fix either way Share this post Link to post Share on other sites
