  1. Problem solved took out bulb to engine warning light ta da!! Well I give in with this silly fault.
  2. Some other symptoms I forgot to mention, when cold the car will idle high then low, irratically only lasts a few seconds and only when cold. But recently the fuel tank would show empty on the digital display when starting up, and the tank is full. I turn the ignition off and on and it reads correct fuel amount, very strange. Any ideas anyone, it sounds like it could ba an ecu on the way out?? Alan
  3. I've checked the O2 sensor connection which is the one after the CAT i believe, looks ok, what connectors and where on the ECU should I look. Is there a diagram which is easy to follow to trace the o2 harness inside the car.
  4. Hmmm I'll check that as I recently fitted a TNS 200 which is spliced into the speed sensor wire. Let you know how it goes. Al
  5. Just remove the EFI fuse for 10 seconds, works great and no loss of stations on radio.
  6. No they are both brand new genuine toyota sensor fitted by toyota. Now my car is running great, still get the p0141 code after 10-30 miles or so. What about the egr/Vacum switching valve?

  8. Nope had CAT checked, all OK. What about a bad wiring harness, or coil?? I'm running low on options. When I disconect the o2 sensor after the CAT it runs great!! Plug it back in and it hop, skips and jumps!! Anyone got any ideas Just an update the code is P0141 O2 Heater Circuit

  10. Yes the code is for the o2 sensor it was the heater circuit can't rember which bank or sensor but it's the one after the cat. P0135 if remeber correctly was the code, but all sensors have been replaced twice with no effect so that rules them out. How can I check the CAT short of replacing it.
  11. Hi everyone, first time I'm starting a post and it's a biggie. Are you seated? Good, we'll begin. Last year I took my car to the garage to get fixed as it had some running problems. It would hiccup and stutter between 1500-3000rpm but if you put your foot down it was fine and it only happened when hot. They struggled to find any problem and there was no check engine light at this point. After going back to the garage several times they replaced the o2 sensors as they could not find anything else to try. This did not fix the problem and the car was sent to Toyota garage. They had the car for 1 Month and replaced things trying to find the problem, they replaced the crankshaft position sensor, they were just about to take the head of, which was not covered by warranty and they noticed the cover of the oil control valve looked tampered with they replaced this and it fixed the problem great!!! The car had a new water pump fitted quite recently, by reg vardy, and its my suspscion they damaged it. So problem solved they test drove and it drove great. I went to pick up the car that night and just as they drove the car out of the garage it ran out of fuel. They put some fuel in for me and I drove it home. On the way home the check engine light came on(C.E.L). I took it back and they said it was on o2 sensor thay reset it but it came back on. They have now replaced all o2 sensors twice!! and still the light comes on. I have replaced the spark plugs, air filter, checked the fuel pump and filter, and replaced the air flow meter myself. ran umpteen fuel treatment through the car and still the light comes on and now it has a little hiccup and hesitates now and then. The light will come on wihout fail within 10-30 miles. Toyota said on my last visit, that it could be a loose or corroded connection within the cars wiring harness but they could not be sure. Please help this has been going on for over a year!!! Any suggestions?? Alan Car Toyota Yaris 1.3 CDX 2000 W reg
  12. Update for you guys with this problem,if it only does it when hot ask mr T to check the oil control valve, that's what mine was, all fixed now after 2 months of searching. Will save you a lot of grief!!
  13. AAAAAAAAGHHHHHH Just had my Yaris back at Reg Vardy again for third time and all they can say is "Computer says no!!" don't they use common sence any more and actually look at the vehicle. I have already change the spark plugs they seem to be burning ok form the colour of the cores but I did notice a bit of oil fouling around two of the pugs when I changed them. I checked it again last week and the new plugs did have oil creeping past the metal O-ring and onto the white ceramic body og the plug. Could this be the source of my problems I told the garage about this problem when I put it in the first time I assumed they would check it out. I asked what they did today and all they've done is drive it and plug it into a diagnosic unit, I asked if they checked the compression or valve clearances as I have just clocked 60,000 and they have not. Somebody help!!!!! Al Mr T now have my car they thought it was an o2 sensor, then they changed the crankshaft sensor. Now they are strippping the engine to check valves. I bought my yaris to have a reliable car but this seems like quite a problem to fix. They have had my car for over 2 months!!. Anyone shed some light on their opinion. The have not changed the ECU but they recon it's not that. Help
  14. Ignore my last post, you cannot use the wirning loom from the tns200 or 300 as there is not enough wires which send the signal to the colour monitor. How do I know I had to take out all of my exsisting wiring after trying to figure out why my tns200 wiring would not work. I have the part number I'll post it here later. also you have to do a bit of splicing to the 12P connector to allow your audio controls to still work will give details if needed. But I now have a TNS500 in my toyota 2000 yaris. MINT!!
