Known Problems

On vehicles with a manual transmission, worn shift bushings can cause the transmission to pop out of gear, especially when coasting down in 1st or 2nd gear. Replacing all the shift linkage bushings is pretty straight forward and not expensive and will commonly correct this concern.

If the engine will not crank over, the most common problem is the starter. These will tend to go out at about 100,00-125,000 miles. Sometimes it is only the starter solenoid, but often the complete starter (including solenoid) needs to be replaced.

The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.

The anti-lock brake system (ABS) may function erratically or illuminate the warning light due a damaged wheel speed sensor. A wheel bearing and/or CV joint with excessive runout can cause the ABS trigger rings to rub against the ABS sensors and damage them.

You may be able to prevent automatic transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned, the transmission system should be completely flushed.

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

A rough idle and even an emissions inspection failure for high HC and CO can be caused by improperly adjusted valves. Also, exhaust valves may become to tight which can lead to valve failures. Our technicians tell us that regular valve adjustment inspections are a must.

At higher mileages, an anti-lock brake system wheel speed sensor may wear out and illuminate the ABS warning light. It is recommended to replace the sensor with a factory part and be sure to clean all rust and debris from the mounting area because the mounting distance is critical. Failure to do so may result in the new sensor setting false trouble codes.

Over the time the exhaust gas recirculation (EGR) system may become plugged with debris, the oxygen sensor may also be getting slow or 'lazy' around this time. When servicing or cleaning  the EGR system, it is a good idea to replace the oxygen sensor because it works in tandem with the EGR system.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

The Ignition Coil, pick-up coil, and radio noise suppressors inside the Distributor are prone to failure. Our technicians recommend to replace the distributor with a complete genuine Toyota distributor if any of its components fail.

The timing belt tensioners may make a rattling noise at a higher mileages. This is due to the adjustment being at its limit. Our technicians tell us that the range of the adjuster may be lengthened by elongating the slot where the spring attaches by 2-3 mm to remedy this problem.

The Throttle Position Sensor can get out of adjustment due to wear in the throttle body or due to carbon build up. This will cause the idle timing to advance more than 30 degrees which will cause very high HC and NOx emissions. Conversely, the Throttle Position Sensors can wear out and not properly advance the timing which causes a lack of power and poor fuel economy.

It is important to regularly check the valve clearance as the exhaust valves may become too tight. This will lead to valve failures which are expensive to repair.

A loss of power on the freeway may due to an internally leaking fuel pulsation dampener. This commonly occurs on higher mileage vehicles.
