Hi There, It sounds like your vehicle may be a bit low on transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) or you may potentially have a bad transmission control solenoid. As you know, the transmission works on hydraulic pressure built up from the fluid...

Hi There, The knock sensor is a component that creates an internal voltage signal based upon vibrations it detects as a result of detonation internally in the motor which creates a knocking vibration. An engine can ping (or knock) due...

An illuminated Check Engine Light can be caused by many different issues on a vehicle that is 15 years old; it could be anything from a gas cap, to a bad sensor. I recommend hiring a mechanic, such as one...

The code P0013 is for a problem with the camshaft sensor or the camshaft actuator solenoid for the variable valve control. Further testing will be needed to see if the sensor or solenoid is in need to be replaced.

If the transmission will not go into reverse or roll back then it is inside the transmission clutch bands worn out or the reverse band servo piston is not moving. Have a transmission specialist test the transmission pressures to see...

There is no history of premature failure of Toyota OEM coils in this application. Aftermarket coils might be a different story, though. A typical cause of coil failure is faulty spark plugs that create a high resistance (or faulty wires...

Hi Jayden. Thanks for contacting us today. It's quite possible that you have a dead battery or bad battery cables. You can try to jumpstart the car, but make sure to pay careful attention to ensuring you connect the cables...

Many vehicles with dual zone climate control will have what is called a dual climate control valve. This dual climate control valve essentially takes the place of the heater control valve. The only difference is The Duel version has to...

The shift solenoids are external on this transmission and can be replaced once the correct one is identified after pinpoint tests of the failure codes are done.

This is caused by a combination of the reversing mechanism built in the motor and the slides getting dry of lubricant. You could have the tracks and slides cleaned and lubricated to see if it helps. If it still does...

Hello there, a few things can cause the AC to intermittently work. The most common would be the AC condenser (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-ac-condenser), AC fan, low Freon, or a failing temperature control module (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-ac-control-module). Depending on how humid your area is, mold...

The first thing to check is to see if the check engine light is on and diagnose any service codes before continuing. If the problem occurs only when the vehicle is first started, then have the fuel pressure checked to...

Fluctuating RPM is not a typical symptom of a mispositioned timing belt. To rule a mispositioned timing belt in or out, though, check engine vacuum. If intake vacuum is 4-5 inches below spec., then that would be consistent with incorrect...

It is very possible that the quality control of those particular parts may not be what it used to be. It just depends on how many times you've had to replace it. Sometimes Parts can last for years and other...

It sounds like the engine stalled but you presently have a no start condition, specifically no starter motor operation. To get the vehicle started, first check to be sure that the engine immobilizer system (security system) is not activated thus...

You're right, this could be a gas cap problem. But it could also be any number of other problems. The check engine light comes on (https://www.yourmechanic.com/article/the-check-engine-light-demystified) whenever the computer detects a fault in the car's emissions systems and the computer...

It sounds like your car needs a new thermostat. The thermostat is a valve that blocks the circulation of the coolant until it reaches a certain temperature. Then it opens just enough to regulate the engine temperature. Thermostat replacement usually...

The code P0420 can be caused by the catalyst, O2 sensors before and after the catalyst. If both O2 sensors and catalyst was replaced then you may have an exhaust leak at the manifold or pipes. I suggest you have...

A clicking noise on turning is often due to failure of the outer CV joint(s) on the axle. If the front end of the vehicle is not tracking smooth and straight, underlying causes of that fault range from wheel and...
