P0859 - OBD Trouble Code

<<See All OBD Codes

Error code P0859? Well, here’s how you can comprehend and crack the error code. When the powertrain control module detects an error relating to the traction control input signal circuit, the code P0859 is stored. Still not there? Well, we have got you covered!

Numerous aspects of the vehicle's drive system specially with no regards to engine power and fuel delivery are all regulated by the traction control system. If when the PCM fails to receive a signal from the traction control system, the trouble code P0859 is stored. 

What causes this problem with the Traction Control Input Signal High?

• A damaged traction control switch leads to the P0859 code being stored in a majority of cases. The switch itself can either be malfunctioning or completely defective. It is often reported by the mechanics that in such cases the switches are damaged due to liquid contact.
• Wires that are shorted or corroded often trigger the code P0859. Also, a defective or burnt sensor connector has been cited by the mechanics to be the most common cause leading to an error code P0859

1. Powertrain Control Module - Abbreviated PCM; this is an integral control unit. So, a defective one should be changed immediately.
2. Traction Control Module - Having problems with the traction control module? Don’t you worry, Parts Avatar has it all. A defective traction control module could end up being the root cause behind the error code P0859.
3. Electronic Brake Control Module - A distorted electronic brake control module can end up being the chief host inviting the error code P0859. So, replacing one can be one of the wisest decisions to avoid a problematic system.
4. Scanner - Weary and damaged scanner can often be problematic. So, to add some spark to your ride you definitely need the perfect quality scanner offered at Parts Avatar. Isn’t that just the perfect deal?

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0859 code by mentioning some major symptoms below:

Common Symptoms

The symptoms for this code P0859 range from strictly traction-related concerns to a fault in the transmission system. It should be noted that specifically if a P0859 code-afflicted car is driven on slippery surfaces, traction issues are most commonly reported. Problems like harsh or failed shifting may also follow as soon as the code is stored. Both the dashboard trouble indicator and the trouble code will be activated. This highlights problem as well as indicates a diagnosis.

Have a look at some ways with which you can correct the P0859 code:

• A faulty or an unsound traction control switch should be replaced or repaired
• Wirings that are corroded, defective or loose should be mended as per requirements
• One should connect the module in question to a memory saver in order to avoid costly reprogramming, if they are being repaired by themselves
• All the voltage readings should be compared to the manufacturer's default specifications
• Lastly, the vehicle should be test driven to make sure the trouble code has vanished

Wondering on how are you going to diagnose the error code P0859? Parts Avatar to the rescue! We not only believe in providing our customers with finest quality products but also ensure equipping them with all the information we got. Here are a few steps that can make the detection and diagnosis easy.

Firstly, using an OBD-II code reader the code should be diagnosed. A thorough visual inspection should be performed of the components related to the traction system (especially the traction control system's activation switch) for any traces of malfunction. All the wirings surrounding the traction control system should be inspected to verify any possible traces of damage or disconnection. A specialized scanner such as an auto hex should be used to point out the error in case the problem lies in the vehicle’s control module.

Common Mistakes When Diagnosing the P0859 Code

Here are a few common mistakes listed that should be taken care of in order to prevent a misdiagnose:

While diagnosing the error code P0859, one might often blame a malfunctioning traction control module, with actually the real problem lying in a defective electrical circuitry or a distorted switch.
