I have toyota yaris 2001 year, 1.0 VVT-I, and I have problem with check engine lamp, that lamp switched and diagnostic said, that is error code P1349 VVT-i. My car dont pull well in a second speed, hear the clicking of something in engine, my mechanic did evrything: replaced engine oil, filters, plugs, one bobin, clean the nozzles, checked valves, chain is new and milled well, cam is good, evrything seems fine, but the engine steel not work well and does not draw well. Bad ignition engines...check engine lamp light up again and again evrytime when he do something on it...

Don't go replacing anything until you have had a Toyota tech check the car and determine the cause or causes of the fault code. It may well also be throwing other fault codes that need attention that will show up on Toyota diagnostic equipment that you have absolutely no idea about.

If the car is accelerating dangerously due to a fault, most likely in an electrical component(s), you do not want to be trying "do it yourself" fixes when you do not really understand what is happening, the exact cause and the correct fix or fixes for the problem.

now this code p1349 means that the v v t-i actuator is dirty and it causes the computer to through that code so if you can you can clean that up and i would put some fresh oil in the engine i hope am of some help

Bank1 failure.

my guess, those DTCs off a cheap scan tool>? why not post source and real codes, no lie P0301 is real. but off what?

real engine: Name.

4.7 L 2UZ-FE V8

VVT-i variant??? got VVT? IF ONE SIDE FAILS, misfire there. if cam retarded. if bad, can be 14deg retarded, (huge)

see cam action here.

2003 Tundra.

if using a full real scan tool that sees all toyota extended DTCs , you might see VVT errors, $20 tools and lame autozoned , blind .

there are 4 sensors there, id bet there are codes you missed!



P0301,3,5, and 7, DTC, ONLY?

bad coil packs? no.



thats the whole left bank, bad.

RF 2-4-6-8

LF 1-3-5-7

so, VVT bad on left bank or coil pack ,

yours has 8 COP coils, so its not 4 bad COPS.

a real mech sees all this in 1 second , online, impossible

nor country. sold.\'



could the timing belt slip only on one side

did you do timing belt service, on time, if not, bingo.



misfire is

bad compression (vvt?)

bad spark , no, not all 4

bad fueling, but there is only 1 maf/map, and one full injection rate there so not fuel mix.related.



here is a tool (most AZ stores clueless)

that reads the enhanced DTC of Toyotas



http://www.amazon.com/gp/product/B001QIUGVI/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1#productDetails



using a 1996 tool , misses the boat.

but id bet your VVT is bad. left bank.

the real tool might help. here.

pit is a timing issue ,could be a vvt actuator or something else in one of the timing components

EOBD II Error Code: P0117
Fault Location:
Engine Coolant Temperature (ECT) Sensor (G62) - Low Input
Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
Coolant thermostat.
Wiring short to earth.
Engine coolant temperature (ECT) sensor.

EOBD II Error Code: P0340
Fault Location:
Camshaft Position (CMP) Sensor A (G40), Bank 1 - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) active.
Wiring from/to Camshaft Position Sensor (CMP) faulty.
Camshaft position (CMP) sensor faulty.
Timing misaligned.
Possible Solutions:
Check Wiring from/to Camshaft Position Sensor.
Check Camshaft Position Sensor.
Check Timing.

EOBD II Error Code: P0500
Fault Location:
Vehicle Speed Sensor (VSS) - Circuit Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL) Non Emission Fault - No warning light.
Wiring.
Vehicle speed sensor (VSS).
Engine control module (ECM).

- Dirty or low engine oil
- Valve timing
- Oil control valve
- Variable Valve Timing controller assembly
- Engine Control Module (ECM)

you can use MVCI check your car and clear the fault codes.

NOTE:Variable Valve Timing (VVT) sensor is also known as camshaft position sensor.
The Variable Valve Timing (VVT) system controls intake valve timing in response to driving conditions.

Possible causes are:

1. Incorrect valve timing P1346, P1349, P1351 & P1354
2. Faulty oil control valve P1346, P1349, P1351 & P1354
3. Faulty VVT controller assembly P1346, P1349, P1351 & P1354
4. Faulty ECM All Codes
5. Jumped timing belt All Codes
   
6. Faulty Camshaft Position Sensor P1346, P1349, P1351 & P1354
7. Faulty O2 Sensor (Bank 1, Sensor 1) P1133 & P1135

Code P1349 VVI Malfunction Bank 1. Bank 1 the difficult side where the intake body is.

This could be from a slight misfire from poor air. Ensure that the gas cap is on fully and not airtrapped.

P1349 - VVT System Malfunction Bank 1

Most likely for this issue you will need to take it to the dealer.
