Without Stability Control the O. P1129 Electric Throttle Control System. Let me know if cleaning it doesn't fix it. While every effort has been made to verify the accuracy and quality of this trouble code summary, we can not be responsible for errors or omissions. Here is a picture of a mass air flow sensor on a 2008 Toyota Rav4.
First is a brief overview of this code. The reading will be different for different automobiles, so get a good spec. If the engine is turbo charged, be sure the hoses are in good condition and have no leaks. If that doesn't do it, it's probably time to enlist the help of a professional. P0153 Heated Oxygen Sensor Circuit Slow Response Bank 2 Sensor 1.
. When testing the fuel pressure on this engine, the specifications are 44. Of course, this code can also signify a bad O2 sensor in bank 1. I'm sure there's a reason for it, but I can't get anyone to tell me what that is. Tech notes If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. Leaking turbo pressure hoses could cause a rich condition.
You can test the mass air flow sensor using a scanner or a voltmeter. I did not cover the Toyota Tacoma or Tundra. What are the causes of the P0170 code? Short of doing these two things first will result in the check engine light coming back on with the same lean code. Keep spraying all around inside and outside throttle bore. If your dealer replaced the wrong sensor; 2 , you can expect to have problems. Do this and reset the codes.
Have flushed the engine and replaced anti freeze, replaced the temperature water sensor, replaced the alternator, fitted new batteries, bought chocolates for the wife but the dam thing keeps doing it. If it is a small one, it should not be heard. However, reversing causes the engine to torque over in a different way, and potentially opens up that crack very wide. P1120 Accelerator Pedal Position Sensor Circuit. Basically it's adding fuel to try to compensate for a lean condition, real or perceived. The same thing applies for rich conditions, with factors like a faulty airflow sensor manifold, faulty fuel pressure regulator, and absolute pressure sensor. You need to clean the Mass Air Flow Sensor.
Air fuel ratio sensor has failed. Common Symptoms Symptoms for Error Code P0170 may vary depending on the make of the vehicle. However, keep in mind, the theory and operation is still the same when it comes to a lean condition on the V8 engine and all other internal combustion engines with this similar Toyota fuel system. In that case, I would recommend to use a voltmeter while backprobing the signal wire at the sensor while the engine is running so you can get a live reading. Symptoms of this code may vary depending on the vehicle and other conditions that are present. If the fuel pressure is lower than the specifications or if the fuel pressure leak down below 21 psi after the engine is turned off, the fuel pump has likely failed and will need to be replaced. P1135 Air-Fuel Sensor Heater Circuit Response.
However, this is not always the case. P0206 Injector Circuit — Cyl. P0510 Close Throttle Position Switch. If the leaking manifold gasket is confirmed following the diagnostics steps, it must be replaced. P1310 Igniter Circuit — No. The intake air temperature sensor is the samll 'bulb'. P1125 Throttle Control Motor Circuit.
What year is your Corolla? With Stability Control the O. The freeze frame data triggered at 30mph. If it is a big one, I don't see it. Low calculated load readings during a wide-open throttle acceleration can also indicate the mass air flow sensor is faulty. If you have any doubt as to repairs on your vehicle, please contact your technician. If this the codes come back, I would probably look at the oxygen sensors, you have two. This is especially the case with Mercedes-Benz and Volkswagen and other European cars.
Everything appeared fine short of a smoke test. You will see 2 small wires, and they will appear fuzzy or dirty. Begine to spray inside throttle body using little red hose that came with carb cleaner. Using a flammable Carb cleaner and the engine running I sprayed around the vacuum hoses until the idle picked up. It is located between the throttle body and the air filter case.
