P070A OBD Error Code: Problem & Solutions

<<See All OBD Codes

Having troubles with your vehicle’s transmission? Is it giving you a harsh time shifting properly? Chances are you have some issues with the transmission fluid level sensor circuit, causing the flashing of OBD error code P070A. Well, now you must be scratching your head thinking what can you do to solve it on your own. Don’t worry as you are at Parts Avatar, we have the best and most budget friendly solutions for you. To know them take a look at the sections below.

If your vehicle is facing low fluid level, then a warning light will be illuminated by your vehicle’s transmission fluid level sensor, also known as the TFL. TFL sensor is responsible for informing your vehicle’s engine control module (ECM) regarding the level of transmission fluid in the transmission. In case it detects that there exists an incorrect signal from the vehicle’s transmission fluid level sensor, it will set the error code P070A. Interested in knowing about few common causes that result in this error code? If YES, then take a look at the section below.

What causes this problem with the Transmission Fluid Level Sensor Circuit?

• Transmission fluid level sensor that is faulty
• Transmission fluid level running low
• Problematic wirings
• Powertrain control module being at fault itself

Common Symptoms

• Flashing of the transmission fluid warning light
• Flashing of the check engine light
• Fall in the transmission performance

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P070A:

• Check and fix the transmission fluid level sensor, if found faulty
• You will need to undergo a complete diagnosis of the related transmission and ignition parts to check for any damage
• In case you come across any damaged transmission parts, then it will be definitely a good idea to replace them with a new one
• If the powertrain control module itself is faulty or facing any reprogramming error then you will need to either repair and fix it or replace it altogether
• Also, check for the transmission fluid level, if its low then it’s definitely a good idea to refill it

However, if you face any issue then we have stocked a wide range of best priced transmission fluid level sensor, PCM, transmission Wiring, transmission fluid warning light, engine light, transmission parts, ignition parts and more to help you out in fixing your car.

Here are some steps which you should follow in order to diagnose this P070A fault code:

• To start your diagnosis, check the transmission fluid level and also the transmission fluid level sensor and all the related wirings. In case you come across any faulty wirings or connection such as loose connectors, corroded connectors etc., then repairing them is definitely a good idea.
• After this, the next step would involve checking the technical service bulletin for information regarding the related issues. I case you do not find anything then you will need to conduct a step by step inspection of your transmission system. You can also refer to the manufacturer’s diagnostic flow chart in order to test the system efficiently.
• We strongly recommend you to inspect the relating wirings before you commence further. Also refer to the factory wiring diagrams in order to understand what wires are what.
• Next on our list is to check the reference voltage side of the circuit while keeping the ignition on. After this you will need to use a digital voltmeter to check the PCM reference voltage which should be somewhere between 5 to 12 volts.
• To be able to do this you will have to connect the negative meter lead to ground and connect the negative meter lead to ground and the positive meter lead to the sensor B+ terminal on harness side of the connector.
• In case you come across out of limit (OL) condition then there might be an open circuit between the PCM and the sensor that you will need to repair after locating it.
• There will exist continuity if the meter reads numeric value. In a situation where everything is good so far, you will need to check for the power coming out of the PCM. In order to do so you will have firstly turn on the ignition and set the meter to DC volts.
• Now, connect the reference voltage terminal on the PCM to the positive meter lead and ground to the negative lead. In case you come across no reference voltage from the PCM, then in that case your PCM is at fault. But the chances of the PCM going bad is quite rare, so we recommend you to do a double check.
• Next, with the ignition off check the ground side of the circuit for continuity by using a digital multimeter set to ohms. To do so connect the meter between the chassis ground and transmission fluid level sensor ground terminal. There will be an open circuit between the PCM and the sensor if you happen to come across the out of limit reading.
• In case everything is fine then it the sensor that is faulty. Now, turn off the ignition and set your multimeter to read ohms.
• Lastly, remove the transmission fluid level sensor connector and connect the meter to the sensor terminals. The sensor will be open internally of the meter reads out of limits (0L), you should definitely replace it in this case.

Common Mistakes When Diagnosing the P070A Code

In order to avoid any misdiagnosis, we recommend you to first check the transmission fluid level and all its related wirings. Also refer to the TSB’s with regard to this issue.
