Got a P1349 the other day when my check engine light came on. It suggested that I was experiencing a VVT malfunction. The OBD code reader lists two probable causes- open or short circuit condition or poor electrical connection. Symptoms include, loss of power, missfire/pinging and this is intermittent. What are common/most likely solutions for this make and model?
RepairPal Certified shops can diagnose and repair your 2002 Toyota Echo. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
1. Verify that the engine oil level is correct.
2. Locate the VVT oil control solenoid on the front of the cylinder head. It has a 2-cavity connector with a solid Red and solid Black wire. Unplug the solenoid, and with the engine running, jump battery voltage and ground to the solenoid. The engine RPM should change and the engine should run poorly and possibly stall.
3. If the RPM does not change, verify that the solenoid operates and the oil passages are not restricted.
4. Follow Toyota TSB #EG009-03 for the updated intake camshaft VVT assembly to repair the problem if everything tests good..
Refer to Toyota TSB #EG009-03. The VVT assembly would be covered for 5 years or 60,000 miles from Toyota
What if the oil level is a little higher than normal? I got an oil change a few days ago and noticed afterwards the level was a bit over the normal mark.
check your cam timing valve assembly part. I got the same thing on my 2000 Avalon (part # 15330-0A010) and the dealer replaced it after i replaced the bank 1 cam position sensor and MAF myself with no improvement. The problem went away immediately after the cam timing valve assy was replaced and it ran like it's good old self. Hope it helps.

Yes proper level would be nice...
