Hello my people, Please I have a toyota siena that is guzzling a lot of fuel. This car was shipped directly from the US and has never been worked on. No issue with the car apart from the fuel ish and the check engine light on. Its bn scanned and it brought forth code p0300 P0301 P0303 Vvt system malfunction bank 1 Please wat could be wrong? Unfortunately the car is in the east as all d professionals seems to be based in lagos. Please I'll need any professional mechanic in umuahia dat can fix this for me. Not kazeeem biko. Lol 1 Like |

AmandaLuv: The error codes your vehicle is experiencing, are in line with the excessive fuel consumption you have started. I am sure if you look hard within your zone, you would find a proper mechanic.... NB: You can export GAZZUZZ to umuahia for this repair. (All extra expenses would be footed by OP) |

P0300 MEANS P = Powertrain Code (engine or transmission) 0 = Generic OBD Code defined by SAE 3 = Ignition System or Misfire 00 = Specific Code for the Exact problem of this ride, we need to consult the code books to tell us what/which circuit and component is at fault which yields the following information: Random/Multiple Cylinder Misfire Detected The P0300 code means that your engine is misfiring but the PCM/ECU is unable to localize the fault to a particular cylinder or to some specific cylinders. 1 Like |

AmandaLuv:All the misfire you have and the VVt malfunction are concentrated on bank 1and this a pattern that the issue is concentrated on bank 1. I am sure your kazeems must have confirmed the ignition systems (sparks plugs ,coil and igntions electricals) and fuel injection (injectors ,fuel pump) ok and thus eliminate that the misfire is due to those factors. Concentrate the effort on the the VVt system on bank 1,check the VVt solenoid ,VVt wiring and the oil for dirts, first and if confirm ok ,then u will need to confirm if the valve timing as the last resort as this can be a clue to the cause of the misfire on bank 1. 1 Like |

Re: I Need A Professional Advice N Mechanic Please by AmandaLuv(f): 9:28am On Jun 06, 2017 |
honmusa:I once took the vehicle to a mechanic who checked everything. He checked the ignition Coil, spark plugs, he also checked the exhaust to see if its smoking/bringing out fuel but none of this and confirmed the vehicle very OK. When I went back to complain of d vehicle still consuming fuel he said I have to buy a new injector that's why I wrote him off becos d car has never bn used in Nigeria and I wondered how I'll start changing parts on a new vehicle. |

AmandaLuv: P1349 MEANS P = Powertrain Code (engine or transmission) 1 = Generic OBD Code defined by SAE 3 = Ignition System or Misfire 49 = Specific Code for the Exact problem of this ride, we need to consult the code books to tell us what/which circuit and component is at fault which yields the following information: Variable Valve Timing (VVT) System Malfunction Bank 1 Blocked Oil Valve Filter Detected The VVT system is partly 1. Mechanical 2. Electrical 3. Hydraulic The key to finding out what is the root cause of the problem is to identify which of these aspects of your vehicle's VVT is out of specification. So simple things first, let's eliminate the hydraulic aspect. What is the oil level? Can you check? And update? What kind of oil do you use? If you have ever done an oil change since it landed in the country? When was the oil last changed? What is the odometer reading? Do you have the complete service history of this vehicle? Can you email me the VIN so I can check how properly maintained it was - assuming it was shipped in from America? I might hasten to add, that the P1349 might be responsible for the P030X codes, so we need to concentrate on and eliminate P1349 as that is capable of eliminating the P030X codes. 2 Likes 2 Shares |

AutoElectNG:Thank u so much sir, the oil was changed a month ago with Mobil(4ltrs) and another Mobil(1litre), the odometer reads 222,145. Dnt know the service history. Will have to ask around to get the VIN number cos I dnt know it. Could d fault be electrical or mechanic? |
Re: I Need A Professional Advice N Mechanic Please by AutoElectNG: 10:04am On Jun 06, 2017 |
AmandaLuv: I need to know the specification of the Mobil Oil that was used. 20w50 5w20 5w30 Secondly, I need to know, before this oil change, was this code there? and the check engine light? How to find the VIN? check the driver's door http://www.oakbrooktoyota.com/blog/location-toyotas-vin-number/ |

Re: I Need A Professional Advice N Mechanic Please by AutoElectNG: 10:46am On Jun 06, 2017 |
AmandaLuv: Please drain this oil Use 5w30 instead Also replace the oil filter And let me know if this code still comes up after a week of driving or after covering no less than 500 miles (800km) But you have not addressed two key aspects of my inquiries - 1. Does this code precede the oil change? Or did it come after the oil change. 2. Is the oil level low? |
Re: I Need A Professional Advice N Mechanic Please by AmandaLuv(f): 11:08am On Jun 06, 2017 |
AutoElectNG:im Sorry. The check engine light has bn there since the vehicle was brought back. The oil level is not low. Please wats d difference in the two engine oil? Which is more expensive as I just spent money changing d oil. Sorry for taking up your time. |
Re: I Need A Professional Advice N Mechanic Please by AutoElectNG: 11:18am On Jun 06, 2017 |
AmandaLuv: Good to know that the check engine light has always been on. Good to know the about the oil level. 5w30 is more expensive than 20w50. 5w30 is what is recommended for your vehicle. Remember that the VVT system is partly hydraulic in nature, by using 20w50, you are using too heavy an oil weight, an oil weight that is does not meet the specifications around which the engine was designed to operate. I could recommend deeper diagnostics, but I want to eliminate the possibility that the oil is responsible for the problem first. You could learn a thing or two from this thread: http://www.rav4world.com/forums/99-4-3-mechanical/165489-sae-5w30-vs-5w40-vs-20w50.html Or you could run the oil for the whole 5000 miles , then at the next oil change switch to 5w30 so we can see if the oil was the problem.

Re: I Need A Professional Advice N Mechanic Please by honmusa(m): 12:04pm On Jun 06, 2017 |
The issue is more than oil change !!Though changing to factory spec oil to is a step in right direction .p1349 DTC code due to using dirt in the oil will not localise misfire to a particular bank and it will not even bring about a significant high fuel mileage noticeable to the user cos it will be an intermittent DTC . I am strongly believe that P1349 that set up a misfire code is electrical(vvt solenoide ,vvt wiring ,ecu) or mechanical (VVt actuator and valve timing ) |

Re: I Need A Professional Advice N Mechanic Please by AutoElectNG: 5:53pm On Jun 06, 2017 |
All I want is to start with a known good baseline - which is using the correct oil, once I discovered that the oil in use is the wrong one. I have already alluded to the fact that this issue could have three angles to it hydraulic, mechanical or electrical. I have also made it clear that I am doing the simple things first. There are several more steps to follow to determine what's wrong/resolve the issue. Jesus said: (John 16:12) . . .“I still have many things to say to you, but you are not able to bear them now." I am taking the steps one at the time, and I will not progress until I receive feedback from the OP that a particular step I recommend has been sorted out, then we can go to the next. There is no need to bombard OP with all that I know at a go, or all the steps that need to be followed. Hope that helps. 3 Likes |
