Pls house, my Toyota sienna bus(2005) is consuming lot of fuel, pls what's the way out

Pls Onyeoma Gazzuz and others
If a car's engine oil fill above gauge; can it affect it operation in way?.
Thanks as always

Yes, over filled oil can lead to froth formation, (air bubbles) making it difficult to properly lubricate moving parts as well as difficult for the oil pump to do its job. Drain excess to prevent stories.

Dear Boss,

I use a lexus RX 300, I recently noticed that the temperature rises every time am speeding and also recline or goes back to normal if not speeding....the coolant is for sure leaking or evaporating, however, i have checked tbrough with a mechanic and cant find d leaking point, i also have to fill d radiator with water daily.....not a thermostat problem as the thermostat is not inside....

Please what could possibly be wrong....

An inefficient cooling system, most times due to blockage. Check for restriction and blockage in the entire system. Also, find that leak and fix it. Hope the engine doesn't blow a blue smoke when revved?

Dear Boss

The mechanic already did that and still can not find the leakage, however we changed some hose as precaution....now the mechanic is talking about changing the water pump.....can this be a possible problem knowing fully well that the temperature is normal when not speeding...it rises only when I speed

I believe a bad water pump will cause an overheat in traffic, not only on top speed. Replacing your radiator is a better attempt. But it is better to check first before throwing parts at the car.

OK, another observation I remembered is that - whenever i opeñ and fill the radiator with coolant, the coolant begins to sip from the top
of the opened radiator cap......I expect the coolant to get sucked-in but not in this case.....can this also assist in you diagnosis

If that does not work, try a new radiator. That was the fix in my case

hello house.
what may be the cause of fan belt not moving.

Pls help is needed

That toyota model is notorious for knock sensor malfunction which would disable overdrive meaning your gear wont get into the final gear.
Your engine 1MZ-FE has a terrible knock sensor which has a fragile socket and its harness could have been chewed by rodents.

To solve this issue, your engine air intake will have to be removed and its 'V' on the engine, exposed to reveal the culprit.
Id advice replacing both wire harness and knock sensor with tokumbo unit removed fron am engine or OEM brand new unit.

As for your heated O2 sensors wires which were snapped cut, replace the heated O2 sensor with genuine OEM denso or direct tokumbo piece. NOTE: the replacement Heated O2 sensor should bear same part number.

Shalom!

Hello house. Thanks for recommending GAZZUZ for the Mobil Oil.

I noticed that while driving, my RX330 2006 gives off a rattling sound like stones in a plastic jar whenever I veer right.

What do you think could be the cause of this noise?

Good day Gazzuzz and other car gurus.

I drive a corolla 2007 sport I bought last October. 
It's engine is heavily slugged cos the former owner was using the wrong oil grade.
So, in December, I flushed it with Liqui Moly and switched to mobil1 synthetic oil
The problem now is, the oil gets short persistently despite driving the car for just once a week, about a 100 km to and fro.

The car drives smoothly, doesn't smoke nor leaks.

What could be the problem sirs and kindly suggest solutions.

Many thanks.

What is d mileage of the car? The issue with most of the car is that mileage will have been around 245,000 MPH but our dealer will roll back to 105,000, I will advise to change d PCV valve and thank me later.

PCV is not 280k oh
Maybe 5k ish.. Your symptoms don pass PCV case but no harm in trying..

Person weh hin car miss dey check under bed, inside gutter..

Any good mechanic that has diagnostic tools that can check Cars in Ibadan (Honda Accord )
Please refer if you know one.

Just wanted to ask if anyone knows of a good and cheap OBD scanner to buy

GAZZUZZ:
What is OBD-II?

On-Board Diagnostic systems are in most cars and light trucks on the road today. During the '70s and early 1980's manufacturers started using electronic means to control engine functions and diagnose engine problems. This was primarily to meet EPA emission standards. Through the years on-board diagnostic systems have become more sophisticated. OBD-II, a new standard introduced in the mid-'90s, provides almost complete engine control and also monitors parts of the chassis, body and accessory devices, as well as the diagnostic control network of the car.


Where'd it come from?

To combat its smog problem in the LA basin, the State of California started requiring emission control systems on 1966 model cars. The federal government extended these controls nationwide in 1968.

Congress passed the Clean Air Act in 1970 and established the Environmental Protection Agency (EPA). This started a series of graduated emission standards and requirements for maintenance of vehicles for extended periods of time. To meet these standards, manufacturers turned to electronically controlled fuel feed and ignition systems. Sensors measured engine performance and adjusted the systems to provide minimum pollution. These sensors were also accessed to provide early diagnostic assistance.

At first there were few standards and each manufacturer had their own systems and signals. In 1988, the Society of Automotive Engineers (SAE) set a standard connector plug and set of diagnostic test signals. The EPA adapted most of their standards from the SAE on-board diagnostic programs and recommendations. OBD-II is an expanded set of standards and practices developed by SAE and adopted by the EPA and CARB (California Air Resources Board) for implementation by January 1, 1996.


Why do we need it?

The Environmental Protection Agency has been charged with reducing "mobile emissions" from cars and trucks and given the power to require manufacturers to build cars which meet increasingly stiff emissions standards. The manufacturers must further maintain the emission standards of the cars for the useful life of the vehicle. OBD-II provides a universal inspection and diagnosis method to be sure the car is performing to OEM standards. While there is argument as to the exact standards and methodology employed, the fact is there is a need to reduce vehicle emitted pollution levels in our cities, and we have to live with these requirements.


Does my car have OBD-II?

All cars built since January 1, 1996 have OBD-II systems. Manufacturers started incorporating OBD-II in various models as early as 1994. Some early OBD-II cars were not 100% compliant.

There are five basic OBD-II protocols in use, each with minor variations on the communication pattern between the on-board diagnostic computer and the scanner console or tool. While there have been some manufacturer changes between protocols in the past few years, as a rule of thumb, Chrysler products and all European and most Asian imports use ISO 9141 circuitry or KWP2000. GM cars and light trucks use SAE J1850 VPW (Variable Pulse Width Modulation), and Fords use SAE J1850 PWM (Pulse Width Modulation) communication patterns. CAN is the newest protocol added to the OBD-II specification, and it is mandated for all 2008 and newer model years.

You may also tell which protocol is used on a specific automobile by examining the connector socket carefully. If the dash connector has a pin in the #7 position and no pin at #2 or #10, then the car has the ISO 9141 protocol or KWP2000. If no pin is present in the #7 position, the car uses an SAE protocol. If there are pins in positions #7 and #2 and/or #10, the car may use the ISO protocol. The CAN protocol uses pins #6 and #14.

While there are OBD-II electrical connection protocols, the command set is fixed according to the SAE J1979 standard.


How do we measure OBD-II output?

Pre-OBD-II cars had connectors in various positions under the dashboard and under the hood. All OBD-II cars have a connector located in the passenger compartment easily accessible from the driver's seat. Check under the dash or behind or near the ashtray. A cable is plugged into the OBD-II J1962 connector and connected to AutoTap or another scan tool. AutoTap is available in PC/laptop. Other scantools on the market range from simple hand-held meters that display trouble codes, up to a large console computer-based unit costing thousands of dollars.


What good does it do to measure OBD-II output?

OBD-II signals are most often sought in response to a "Check Engine Light" appearing on the dashboard or driveability problems experienced with the vehicle. The data provided by OBD-II can often pinpoint the specific component that has malfunctioned, saving substantial time and cost compared to guess-and-replace repairs. Scanning OBD-II signals can also provide valuable information on the condition of a used car purchase.


Tell me about that "Check Engine Light".

The service industry calls the Check Engine light on your dash an "MIL" or Malfunction Indicator Light. It shows three different types of signals. Occasional flashes show momentary malfunctions. It stays on if the problem is of a more serious nature, affecting the emissions output or safety of the vehicle. A constantly flashing MIL is a sign of a major problem which can cause serious damage if the engine is not stopped immediately. In all cases a "freeze frame" of all sensor readings at the time is recorded in the central computer of the vehicle.

Hard failure signals caused by serious problems will cause the MIL to stay on any time the car is running until the problem is repaired and the MIL reset. Intermittent failures cause the MIL to light momentarily and they often go out before the problem is located. The freeze frame of the car's condition captured in the computer at the time of the malfunction can be very valuable in diagnosing these intermittent problems. However, in some cases if the car completes three driving cycles without a re-occurrence of the problem, the freeze frame will be erased.

OBD-II and your car's health

Because of their investment in the equipment required, most repair shops charge a fee, some-times substantial, to attach the scanning equipment and diagnose problems using the OBD-II system signals. Home mechanics and small shop technicians have been restricted from working with these signals by the cost and technical complexity of the equipment. With the introduction of more economical and user friendly scanning devices, it is now practical for almost anyone to access OBD-II signals and use them for their own testing and repairs.

Scanners vary greatly in their complexity. The best connect easily and use software to quickly and automatically call up the OBD-II information. A system connecting to a laptop or desktop computer provides expanded memory for data and a graphing utility.


Proprietary Sensor Readings

Though not part of the EPA's OBD II standard, the diagnostic read-outs used by dealership technicians are also read through the OBD II connector. These service codes show you such things as knock sensor operation, FI pulse width, ignition voltage, individual cylinder misfires, transmission shift points and ABS brake condition.  There can be over 300 readings available, depending on the vehicle manufacturer and model. Vehicles vary in the readings they will support. Scanners vary widely in the number of these signals that they can read.  Some show just the basic OBD or OBD II signals, others show the full range of service codes.


OBD-II and performance tuning

While the vast number of drivers want nothing more than dependable, economical transportation, many of us are looking to OBD-II for extra performance. Earlier on-board computer systems had chips that could be replaced to adjust engine parameters for extra speed and power. While the OBD-II systems are sealed and do not allow chip replacement, they do provide a real time data acquisition system that is useful to tuners.

Power loaders can actually reprogram the performance parameters of the OBD-II system to accommodate performance options. At the current time the number of models they can service is limited, but the range is being extended. Be sure the person doing your reprogramming keeps the car in compliance with EPA emission standards. As aftermarket manufacturers develop additional solutions, we will add their information to our links.

I think their is some debris inside your engine that needs to be flushed out. Try to see a mechanic soon so it doesn't cause unnecessary damage to your engine.

Cheap is relative, what's your budget. If you can do up to 100usd then I will recommend bluedriver

I bought Toyota avensis 2000 model. The formal owner converted it from injector to carburetor. The problem is, the car is consuming a lot of fuel. In fact the fuel consumption is double. What should I do to reduce fuel consumption. They have try to set the carburetor but no solution yet.
