Check around the air filter area (that's where it is on my car). I just noticed mine was bad. I have a scanner that is used to read codes and gives live sensor data. I noticed my intake air temperature was always showing from 170-172 degrees, regardless of outside air temperature and period of time that car was running. I hooked the scanner up to my truck and saw a more expected 45 degrees on this 40 degree day. Autozone (and several other auto parts chains) will hook up your vehicle for free to check this out.
The intake air temperature sensor can be found on the top of the air intake manifold. The temperature sensor should be labeled as such.
In a 2003 Toyota Tacoma PreRunner, the air intake temperature sensor is typically located in the air intake manifold or near the air filter box. It measures the temperature of the incoming air to help the engine control unit (ECU) optimize fuel injection and ignition timing. To access it, you may need to remove the air intake assembly for better visibility.
It is part of the mass air flow meter which is located in the air intake tube just after the air cleaner.
The IAT sensor on a Toyota Tacoma is found inside the air intake. The sensor clips into the plastic tubing used for the air intake system.
The 2006 Toyota coolant temperature sensor is located on the front of the engine. The coolant temperature sensor will be a few inches above the thermostat housing.
On a 2007 Toyota Tacoma, the Intake Air Temperature (IAT) sensor is typically located in the intake manifold or the air intake duct, depending on the engine configuration. For the V6 engine, it is often found near the throttle body. If you’re working on the 4-cylinder engine, it may be integrated into the mass air flow (MAF) sensor. Always consult the vehicle's service manual for precise location details.
The knock sensor for a 2009 Toyota Tacoma is typically located on the engine block, near the intake manifold. Specifically, it can be found on the driver's side, beneath the intake manifold. Accessing it may require removing the intake manifold for proper replacement or inspection. Always refer to the vehicle’s service manual for precise location and procedures.
should be on air intake hose
In a 1999 Toyota Tacoma, the mass air flow (MAF) sensor is typically located in the intake air duct, between the air filter and the throttle body. It is usually mounted directly on the air intake tube, making it accessible for inspection and replacement. To locate it, follow the air intake from the air filter toward the engine, and you should find the MAF sensor along that path.
The mass air flow (MAF) sensor on a 2005 Toyota Tacoma is located in the air intake system, specifically between the air filter and the throttle body. It is usually mounted on the air intake duct. To access it, you'll need to remove any necessary components that may obstruct the sensor. Make sure to disconnect the electrical connector before removing the sensor for maintenance or replacement.
Under the intake manifold above the fuel filter. Hard to see, hard to reach.
