Invalid data received from a control module

What it means

Here the modules are talking, but one is sending information that another cannot believe, such as a wheel speed that is impossible. The receiving module sets the code. The real fault is usually a sensor problem in the sending module.

Codes in this group

Bank 1 is the side of the engine that has cylinder 1. Sensor 1 is before the catalytic converter and sensor 2 is after it. More terms explained.

What you may notice

• Warning lights for ABS, traction control or gearbox
• Cruise control or stability control switched off
• Odd gear changes

Common causes

Most likely first:

• A sensor fault in the sending system, such as a wheel speed sensor
• Mismatched software after one module was replaced or updated
• Low battery voltage

What to check first

• Read the codes stored in the sending module: they normally show the real cause
• Fix those first, then clear this code

Have a mechanic confirm. A fault code tells you which system reported a problem, not which part has failed. The same code can have several causes, and they differ between car models. Use this page to understand the code, then have a qualified mechanic test the car before any part is replaced.

After the repair

Once the cause is fixed, the code can be cleared with a scan tool, or the warning light goes out by itself after several trips without the fault. Clearing a code without fixing the cause only hides it for a while. More about clearing codes.
