Input Circuit for Engine Speed on Ignition or Distributor Does Not Have a Signal, P0322 Volkswagen and Audi Error Code
The DTC P0322 for a Volkswagen or Audi shows a wide variety of potential issues. It’s possible that this is something you can diagnose on your own and fix, or it might be something else different. When this DTC is stored, the description will often read “Ignition/Distributor Engine Speed Input Circuit No Signal,” “Engine Speed Sensor (G28) – no signal – intermittent,” or something along those lines. In rare cases, the description may read “Engine Speed Sensor (G28) – no signal – constant.”
Exactly what does this imply, then? It may be interpreted in several ways. It’s possible that the crankshaft and the distributor aren’t lined up properly, or that the Powertrain Control Module (PCM) has detected an unusual input coming from the crankshaft position sensor or the distributor. Statistically speaking, the second option is more likely to be correct.
The PCM is unable to regulate fuel flow or ignition timing when it receives an invalid or non-existent input from the crankshaft position sensor. Ignoring this issue might result in expensive engine repairs down the road, which brings us to our next inquiry.
I have a P0322 error code on my Volkswagen or Audi; am I safe to drive?
Turning the key to start the car usually results in the car stalling or turning off. As a result, this is not something that often requires debate. There are, however, situations in which the car will continue to operate normally. For the reasons described above, it is strongly recommended that you do not operate the vehicle while the P0322 DTC is present.

Fixing a Vehicle with the P0322 Engine Error
Although this DTC may appear in other Volkswagen and Audi engines, we will focus on the 2.0t engine and how to diagnose and repair it. Please let us know in the comments if you’re seeing this code and don’t have access to a 2.0 version of your car.
The Best Way to Determine Whether the Crankshaft and Distributor Are Out of Alignment
When this is the problem, although it isn’t very often, your engine will operate extremely badly and you’ll get a fault code P0300.
Determine If Your Crankshaft, Camshaft, or Distributor Is Bad. Tracking Device
The P0322 DTC is mostly caused by a problem with the crankshaft position sensor in your car. If it doesn’t solve the issue, then try the camshaft position sensor and the distributor position sensor. These aren’t easy DIYs even if you have the right equipment, so if you’re not confident with your abilities, we recommend taking it to the shop.
Methods for Detecting Broken Wiring, Connectors, and Harnesses
This may be a very time-consuming job, but it might be the cause of the DTC your car is showing.
Summary for The VW/Audi P0322 Engine Fault Code
To sum up, the DTC P0322 is more often than not caused by a defective crankshaft position sensor in a Volkswagen or Audi. Driving on this code is not advised since improper engine timing might result in expensive repairs. Verify your vehicle’s compatibility with any of the aforementioned replacement components before purchase. Leave a comment telling us whether it fixed the engine error!
