When these readings reach below a certain level, the code P0129 is set. It sounds like your tps sensor is probably bad or the circuit to one of those 2 sensors. My car has an automatic transmission. I'm unable to take it out of town to the nearest mechanic and need to use the vehicle to get to and from work. Consult the service manual or information service for technical service bulletins that apply to the barometric pressure sensor, manifold air pressure sensor, or mass air flow sensor of your vehicle. Repair or replace open or shorted circuits as necessary.
You're welcome to contact me! Thanks Mike Aug 03, 2011 check for vaccum leak at map sensor or anywhere else no vaccum to map will show up as bad because the computer watches the voltage on it and the vaccum changes that voltage , no vaccum meens no voltage change and computer throws the light on to let you know there's a problem somewhere. Connect the scanner to the diagnostic connector and retrieve all stored codes. Clean and tighten terminal ends as required. With that being said, you will want to have the sensor replaced if cleaning does not solve the issue. As a reference, altimeter calculations used in global positioning systems have a resolution of about 20-meters. For more diagnostic or repair help, contact our to schedule an appointment. Fur Bottom Best Luxury 3d mink eyelashes bottom? P0442 Evaporator Emission Control System Leak Detected small leak This is caused by a decrease in expected fuel tank pressure.
Consult the service manual for exact specifications pertaining to your vehicle. Unplug the electrical connector and check resistance across all circuits, using the. Damaged wiring or corroded connector faces must be repaired before continuing the diagnostic process. What you want to look any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Replace the sensor if it fails to comply with specifications. The problem is that the sensor may not be the issue and it may be the circuits that feed info to the sensor.
In most cases, whenever the code P0128 is present, the thermostat is replaced. Two days ago I was driving it home from work and the engine stalled twice. If you have a scan tool with live data, check the engine temperature when the engine is cold, it should be close to outside temperature. Engine misfire codes should be diagnosed and repaired before attempting to diagnose this code. The issue needs to diagnosed and repaired first. The vehicle is likely having an issue with the air intake sensors. I bought brand new green sensor from dealer and replaced old blue sensor.
Connect the scanner to the diagnostic connector and retrieve all stored codes. Some car manufacturers then close the vent solenoid but leave the purge solenoid open. Atmospheric pressure is directly related to the particular degree of altitude, as it applies to your vehicle. Here is a brief explanation of some of the most common designs. Perform an engine vacuum test to ensure that the engine is making sufficient vacuum. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one.
If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. Without a scan tool, the engine temperature sensor can be tested with an ohmmeter. Check battery terminal ends for excessive corrosion. The pressure is translated to and measured in voltage and the electronics that create the voltages could be at fault. Make sure that system reference voltage and ground signals are present. Drive a car for 10 minutes and check the engine temperature again, it should be close to 180-220°F or 82-105°C.
My car has 107000 miles. Reinstall and make sure to give the gas cap a full 5 to 6 turns. The problem is that the sensor may not be the issue and it may be the circuits that feed info to the sensor. Posted on Nov 02, 2009 Code u110c no fuel level Remove the gas cap from the van. Most sensors on your trans.
On your specific vehicle it should be measured with the Mass Airflow Sensor. P0442 Evaporator Emission Control System Leak Detected small leak This is caused by a decrease in expected fuel tank pressure. Is there any suggestions you can give me to fix my vehicle? These types of systems are also subject to malfunctions caused by an extremely dirty air filter element. I leak in the evaporator hose or canister or in some cases a gas tank replacement. This is a good time to check battery voltage capacity and alternator output. Their is no way a backyard mechanic can do this without the proper tools to diagnose and with the knowledge to not cause further damage. This is a communication problem between computers.
I got code P0129 last week after replacing cylinder 6 coil pack and spark plug. Automotive barometric pressure sensors are very accurate with a tolerance of approximately one-meter. Conditions such as clogged catalytic converters, restricted mufflers, and low fuel pressure may also contribute to a loss of engine vacuum. This is a communication problem between computers. Since a single electrical connector is used in this system, the diagnostic process can be challenging. After driving for a short time 30-45 minutes I got the code P0175. The computer notices the canister is empty when it detects a leaner condition all the vapors are used up and it resumes normal fuel delivery.
Consult the service manual for exact specifications pertaining to your vehicle. This is a good time to check battery voltage capacity and alternator output. My first guess is you have a bad computer or an open wire somewhere. The pressure is translated to and measured in voltage and the electronics that create the voltages could be at fault. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. I normally begin my diagnosis with a visual inspection of any system related wiring harnesses and connectors that I can gain access to in a reasonable amount of time. Consult the service manual or information service for technical service bulletins that apply to the barometric pressure sensor, manifold air pressure sensor, or mass air flow sensor of your vehicle.
