My toyota gaia has an engine check light on what is the problem


You need to connect it to a code reader. That gives you the code, the code tells you the problem and the fix. A local garage will usually read the codes for no charge in the hope of getting the work. It takes less that 2 minutes to do. Or you can get a code reader and do it yourself.

Fast idle land rover discovery


I had the same problem on my 96 Discovery. It turns out, if the low end of the new TPS reads even a little bit higher than the old TPS, then the engine will rev high. It can be reset at LR dealership to map the new TPS, or you can hog out the screw holes on the new TPS and turn it clockwise until it reads as low or lower than the old TPS, or you can try cleaning the old TPS and reinstalling it. I was able to fix it by rotating, but I also was able to read the TPS signal at the OBD2 diagnostic port.

Replaced the O2 sensor unit and the ECM(programs installed) but I'm still getting CHECK ENGINE LIGHT(P0001). what is the possible problem and how can this be resolved?


P0001 Fuel Volume Regulator Control Circuit/Open The above code is about an oxygen sensor code for the heater circuit located in bank 1 sensor 1. (bank 1 is at exhaust manifold by the #1 cylinder head, bank 2 is on the 2nd cylinder head. On some engines, both exhaust manifolds could have one oxygen sensor each side and the 2nd cylinder head will have the sensor 2). On the oxygen sensor itself, it has 4 wires which are color coded. Two of wires are for the heater circuit that heats the oxygen sensor to make it reach optimum operation quickly. Those 2 oxygen sensor heater wires could be shorted between the sensor and the ecm (engine computer) or other engine components.
oxygen%20sensor%20heater%20copy.jpgThe common fix for this code is to check the integrity of the heater wires. Check the wires for insulation and routing which could be loose or touching a hot exhaust that can short the wires. If the engine has too many miles, it is possible that the heater circuit inside is worn and shorted which needs a replacement of the oxygen sensor. If you have a DVOM, you can also test the continuity of the heater wires from the oxygen sensor to your computer pins.
More detailed fixes will be provided as soon as you give the symptoms of the obd2 trouble code. ATS will provide the wiring diagram so you can trace the color coded wires. Use an obd2 code reader or scanner so you can access this obd2 trouble code. When you have this obd2 code list, use it as a reference and give the code to ATS. We will then send you all the possible fixes for the obd2 trouble code. ATS has lots of fixes for obd2 gm codes, obd2 ford codes, dodge obd2 codes and all obd2 import codes such as Toyota obd2 codes, Honda obd2 codes, Nissan obd2 codes, etc. All fixes for this obd2 codes are guaranteed or your money back.
Important TIPS about Oxygen sensor:
The oxygen sensor content of the exhaust gas indicates when the engine mixture is operating lean or rich. When the oxygen sensor detects that the engine is operating rich, the signal voltage is high, and any decreases in the signal voltage means the engine running is lean. The engine computer supplies a reference voltage like one volt or five volts, and then shows the change in the sensor return voltage as the sensor's resistance is changing. If you have connected everything properly, when you crank the engine, you should see the check engine light coming out.
Unheated oxygen sensors rely on the heat of the exhaust gases to reach the working temperature, therefore they might start to cool down while the engine is idling and revert back to a default air-fuel ratio setting. This type of sensor usually has a single wire connector, though others have two. Unlike the fuel pump relay, the 02 sensor heater circuits have a separate fuse for each sensor and grounds, which are controlled by the engine computer.
To read a voltage across the heater, one side must be connected to (+) and one side must be connected to (-), which is accomplished by the computer or a transistor. It can read 12V between each wire and a separate ground if it was connected to positive and the other was not yet connected to ground connection (for details, please contact ATS).after you replace oxygen sensor you have to drive for so many miles before it resets its sef

My 98 land rover discovery is very hard to start in the morning but when it does it blows out white smoke from the exhaust until the car warms up, then nothing comes out if the exhaust and it drives...


Gas should be black so you may have a problem inside the tank. Rust is the first thing to come to mind.
Also white smoke is usually a sign of water in the combustion chamber. So you may also have water in the fuel tank too. I would guess that there is a hole in the fuel-tank. Do you smell fuel inside or at the rear of the vehicle? Because the car has a OBD2 port you should be able To have generic codes read. So bring it to Auto-zone and see if they can plug into your car's OBD2 port. They provide this service for free. The only other way to have codes read is to bring it to the dealer.
