#215 of 914 ......slight pinging......
Jan 07, 2007 (10:28 am)
I have a 2000 Echo sedan with 250,000 kms on it. Love the car and have never had any mechanical problems. A few years ago I did encounter a slight pinging sound at low speed and low load. It sounded like the timing was off. I know these cars have the variable valve timing and adjustments are non-existent. I did the routine maintenance by changing plugs, air filter, etc. The problem did not completely go away. It turned out to be belts that were loose and slipping. I had the belts tightened in the meantime but eventually replaced all the belts with Toyota parts. All went well until about two months ago. The pinging has returned and now I notice it at all times and all speeds. On the highway there is no pinging unless I put the car under slight acceleration. I never go over 100 kph. I have had the belts tightened and cleaned but the problem still persists.

Could be carbonization in the combustion chambers (this has the effect of raising your compression ratio) or possibly could be a faulty knock sensor that is supposed to adjust your timing as you drive?
You might try using premium gas and see if that temporarily cures the problem. Using premium might be cheaper than digging into the car to fix it otherwise.
Slight pinging is okay, but continual pinging under load is dangerous for an engine.

Thank you Mr. Shiftright. I will go with the premium gas solution first. Using premium fuel wouldn't eliminate the carbonization, would it? All the 250,000 kms are highway miles so I wouldn't think carbonization should be an issue. As for the knock sensor....where would it be located and is it just a feature of the computer?

Here's info on a knock sensor and what it does:
Location varies with the car. Sometimes on the intake manifold or sometimes on the engine near the bell housing. Usually it's "high up".
No high octane fuel won't get rid of carbonization. Some additives claim to do this but I'm a bit skeptical. Heavy carbon is very tough to remove. It's even hard to scrape off with a knife!

Thank you once again Mr. Shiftright. I hope to find a solution to the pinging in the next week. Once I do I will post the answer.
#220 of 914 Re: exhaust leak [sidnee27]

I have a 2000 Echo I had a small exhaust leak it was under the center console so to speak there is a joint there where the exhaust comes out of the motor and bends to go straight under the veh. I took it to a local muffler shop they fixed it for $100.00 it was worth it because I delayed a little and the leak got worse and fumes started to come in the car. I hope this helps

Well I did take care of the pinging problem. I had two or three people test drive the car but only one mechanic told me it was the belts. I told him how they were serviced and should have solved the problem. He recommended a pair of Goodyear Gatorback belts. I tried them and he was right.
Mr. Shiftright.....thank you for all your help and sorry to have been such an inconvenience.
At present I am trying to score a sweet deal on a 2003 Echo sedan with 27,000 original kms. We may become a two Echo family.
#222 of 914 Looking to find Borla Axle-back exhaust
Feb 07, 2007 (5:10 pm)
Maybe it's just me, but I'm finding it hard to locate a place that sells the axle-back, twin outlet pipe exhaust for the Echo Hatchback. I live in Toronto and would probably have to order it ... I know. But even on ebay, on the web in general, I'm having a hard time finding aftermarket hop-ups for my RS.
Does anyone know any places (other than the dealership) that I can order/pick up parts for my RS hatchi?
#223 of 914 Brakes, Rotors, Pads
Feb 23, 2007 (12:20 pm)
In April of 2005 I had to replace Front Rotors on my 2002 Echo at 29,000km at a cost of $112 labor and $110 Parts They were rusted out and could not be machined. I contacted Toyota Canada and after review they sent me a $200 voucher. I now have a 2005 Echo that required front pads, shims, machining of rotors(caught in time), and caliper servicing at 19,360 km (16 months) at a cost of $282.56. I have contacted Toyota Canada again and am awaiting their review for compensation. I have read some other comments and this seems a little too common. I love the Toyota product and quality, but I think they need to reconsider their out sourcing of brakes and brake components. I noticed in message 183 on Sept 20 that "jmrbk" had his rotors covered under warranty at 18,000 km. Is that because they were warped and not rusted. I was under the impression that brakes and components were not generally covered under warranty. Anyway, will get back when Toyota is done reviewing my file.

Yes, the first time (at 18,000 miles) the rotors were warped and they did cover it under warranty. The second time, they were rusted and I had to pay for new rotors. I wrote a lengthy letter to Toyota in California and they did compensate me $400 (I spent close to $500). The way that worked, though, is once I had receipts totaling $400 or more worth of work at a Toyota service dealer, I could submit them and they would then send me a check for $400. I did that this past December and they did quickly send me the check.
At this point, I am planning on needing to replace the rotors every 18,000 miles (which seems totallly illogical) but Toyota denied any known defects.
Good luck! I will be interested to hear what Toyota - Canada tells you.
