Where is a air temperature control sensor in a 2004 GMC Canyon located at


There is none on your vehicle , temperature control is by a cable .There is a evaporator temperature sensor , this is used to keep the evaporator from freezing up !
Air Temperature Control The air temperature control regulates the HVAC system air temperature in any mode. An air temperature control cable mechanically links the air temperature control to the air temperature door.
Evaporator Temperature Sensor The evaporator temperature sensor will not allow an A/C request to the body control module (BCM) at temperatures less than 0°C (32°F).

1995 honda odyssey starting problems


Hello! in 1995 stored trouble codes used the On Board Diagnostic I software (OBDI)..Scanners will not work...The control unit LED can indicate any number of simultaneous component conditions by blinking separate codes, one after another...An instrument panel mounted indicator lamp will light and stay lit. If the lamp is on, or if a system malfunction is suspected even though the lamp is off, it is necessary to inspect the electronic control unit LED display. The LED display is on the ECM (ECU), which is located just below the RH side of the instrument panel. The indicator lamps operate whenever the ignition is On and a DTC is stored in the ECM (ECU) memory.
When an abnormality is detected the ECM (ECU) display blinks. The LED blinks a certain number of times, with the number of blinks indicating the number of the DTC. After the LED blinks a number of times there will be a two second pause and the LED will blink out the number of the next DTC..here are the codes..If there is a code send it to me...If there isn't a code I'll take it from there...guru.saailer

After going over 40mph the check engine light goes on n it gives the code 440


How did you read that code on your car? A 92 Accord is supposed to give you pre-OBD honda codes, which are all below 100. Please check the code again and re-post it.

Fix engie light code p0442 Evaporative Emission Control, small leak detected


OBD II Code P0442 Evaporative System Malfunction, Small Leak Our emissions expert has put together the following information about the P0442 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
Related Information Check Engine Light
Emission Gas Definitions

OBD II Fault Code
  • OBD II P0442
Fault Code Definition
  • Evaporative System Malfunction, Small Leak
Symptoms
  • Check Engine Light will illuminate
  • In most cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be a noticeable fuel odor caused by the release of fuel vapors
Common Problems That Trigger the P0442 Code
  • Defective or damaged fuel cap
  • Distorted or damaged Fuel Tank Filler Neck
  • Small tear or puncture in the Evaporative system hose(s) and/or Carbon Canister
  • Defective Fuel Tank Sending Unit gasket or seal
  • Small split in a seam of the Carbon Canister
  • Defective Evaporative Vent Valve and/or Evaporative Purge Valve
  • Defective or damaged Fuel Tank
  • Defective Fuel Tank Pressure Sensor
  • Defective Leak Detection Pump
  • Slightly loose and/or worn clamps or hardened O-rings anywhere in the EVAP system
Common Misdiagnoses
  • Fuel cap
  • Evaporative Purge Valve
  • Evaporative Vent Valve
Basics
The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions-dictated by engine temperature, speed, and load-the EVAP system stores and purges these captured fuel vapors back into the combustion process.
Want to Learn More?
The EVAP system is designed not only to capture, store, and purge any raw fuel vapors that leak from areas in the Fuel Storage system, but also to run a series of self-tests that confirm or deny the operational and vapor holding ability of the system. This is an important task because at least 20 percent of vehicle-produced air pollution originates from malfunctioning Vehicle Fuel Storage systems.
There are many ways to "leak test" the EVAP system, but most perform the leak test when the vehicle is sitting (like over night) or during the initial start-up after the vehicle has been sitting over night. The EVAP system's operational performance is also tracked by the Power Train Computer by reading the change in the oxygen sensor voltages and short term fuel trim whenever the stored vapors are released or "purged" back into the combustion process. These values should indicate that fuel is being added to the system and that the overall mixture is getting richer. The purging process occurs when the vehicle is under acceleration, which is when most vehicles require additional fuel.

P0442 Diagnostic Theory for Shops and Technicians
The P0442 code indicates that there is a small leak in the EVAP system, but this is somewhat misleading. What the code really indicates is that the EVAP system will not hold a specified level of vacuum for a specified amount of time when it performs its leak test.
Here is how the evaporative leak test is performed by the Power Train Computer:
  1. When the leak test is performed, the vehicle must have been sitting for at least four to eight hours so that the engine temperature and outside air temperature are identical. There must also be between 15 and 85 percent fuel in the tank-this is to provide a baseline for the test since gasoline and diesel are volatile fluids that expand and vaporize easily with warm temperatures.
  2. When the leak test initiates, the Vapor Canister Vent Valve is closed to prevent any fresh air from entering the EVAP system. The Purge Valve is also sealed off.
  3. The Leak Detection Pump operates to build a vacuum in the entire Evaporative System (see the Leak Detection Pump information below). After a specified time interval-usually about ten seconds-the Purge Valve is shut off and the vacuum level in the system is measured by the Fuel Tank Pressure Sensor.
  4. Finally, a countdown initiates, which measures the rate at which the vacuum decays in the system. If the vacuum decays faster than the specified rate on two successive tests, then the Power Train Computer will fail the EVAP system and trigger the P0442 code. Most modern EVAP systems will fail the leak test with a pin-sized hole anywhere in the EVAP system, which amounts to 0.020 of an inch or a ½ millimeter.

Ask your autoparts store how much the parts are and decide if it has a point to even do it, its a 19 year old car. You should also ask if that employee works on the side and would do it for you, if you aren't comfortable.
