Question about 2004 Toyota Avalon

VSC and TRAC OFF problem

The VSC Warning Light and TRAC OFF is on. The EGR Position Sensor was replaced, the injectors cleaned,fuel line pressure okay, ECT sensor okay, no water in fuel tank, brake fluid level okay, but lightis still on. The dealer service mechanics are at a loss to the reason. Four times in their shop.After each time at the shop the light stays off for about ten days then comes back on again.

I'm working on a 2000 suzuki esteem 4 door car it acts like its not getting enough fuel but has good fuel pressure


The air filter is okay?
Personally, I would look at the MAF sensor - try disconnecting the electrical connector and driving the car. A warning light will appear on your dashboard, yes .. but if the car behaves as it should that points towards a faulty maf sensor.

Also try removing and cleaning your EGR valve

Here's a couple of links that may help:

problems with egr valve and catalytic converter for suzuki esteem 98


You can also try disconnecting the O2 sensor - see what the car runs like.

My advice would be to NOT follow all the advice you get. Try things yourself. Your car runs ... but somewhere in the MAF sensor- EGR valve - O2 sensor there's a glitch. Do the simple things first - disconnect the MAF, clean the EGR ..

Vsc code c1336


That code relates to a crankshaft position sensor signal. It you have a check engine light come it disables the VSC and Trac system. Until you get that sensor fixed the VSC and the TRAC system will be inop. So whenever you have a check engine light come on that is what you will see. Even though you cancel the check engine light the fault still exists and the VSC/ TRAC light will come back on. That is a sure way to tell that something is wrong.

There can be a misfire too from the cylinders.

An engine that hesitates, stumbles or misfires when accelerating or when it is under load is an engine that is either sucking too much air, not getting enough fuel or misfiring. If the Check Engine Light comes on, you may find any of the following codes:

• P0171, P0174 Lean fuel condition codes
• P0120 to P0124 Throttle position sensor codes
• P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR related codes

If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.

Another common cause is dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your scantool. If the numbers are high, it tells you the engine is running lean and the injectors need cleaning. Treat mild cases with a high quality fuel-injector cleaner additive. Severe cases require professional cleaning equipment.

Also if this sensors apply to your vehicle, camshaft sensor or crankshaft sensor if sensors bad you don't get any spark. Also run a scan on the car.

Good luck and rate this solution, please.

Check the fuel pressure, fuel pump (which is inside the fuel tank), fuel pressure solenoid (if fitted) and fuel pressure regulator (if fitted). Check and replace the fuel filter and check the injector flow rates in case you have clogged or faulty injectors.. I would lean towards a fuel supply issue here so look at the fuel filter and fuel pump first..

If the light came on it should have a code for a scanner. That would indicate the problem. But there are a few things to look at. Under the airhorn which bolts to the intake manifold there is a breather groove for the EGR valve. This groove must stay clean.

Since you are demanding more EGR flow with higher speeds the blocked groove is causing a restriction and causing the other components to trip a warning.

I do not know your Pollution equipment. On older U.S. cars there were airpumps that were belt driven and some had a type of air filter that needed cleaning.

Another part called a (TPS) throttle position sensor can affect the engine performance.

Check your switches for the VSC, some get bumped on (due to their location) and some get stuck in the "on"position.

1999 Ford Taurus mechanical problem


Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
