Imagine this: you’re about to embark on a road trip, the engine hums to life, and then, silence. The dreaded crank, no start. Could it be your crankshaft position sensor, or CPS, acting up? Before you panic, remember a trusty Autel scanner can be your best friend in this situation.
Understanding the Importance of Your Vehicle’s CPS
The CPS is like the conductor of your engine’s orchestra, sending crucial information to the Engine Control Unit (ECU) about the crankshaft’s position and speed. This data is vital for fuel injection, ignition timing, and ultimately, keeping your engine running smoothly.
But how do you know if your CPS is faulty? Autel scanners, with their user-friendly interface and powerful diagnostic capabilities, can help you get to the bottom of it.
Demystifying the “How to Check CPS Autel” Question
Checking your CPS with an Autel scanner isn’t as intimidating as it sounds. Here’s a step-by-step guide to make the process a breeze:
-
Connect Your Autel Scanner: Begin by connecting your Autel scanner to your vehicle’s OBD-II port, typically located under the dashboard on the driver’s side.
-
Power Up: Turn on the ignition but don’t start the engine. This allows the scanner to establish communication with your car’s computer system.
-
Navigate to Engine/Powertrain: On the Autel scanner’s main menu, select “Engine” or “Powertrain.”
-
Select “Live Data”: This option displays real-time data from various sensors, including the crankshaft position sensor.
-
Locate “Crankshaft Position Sensor” or Similar: The exact name might vary depending on your vehicle make and model. Look for readings like “RPM” or “Crankshaft Position.”
-
Interpret the Readings: If the scanner shows readings while cranking the engine, the CPS might be working correctly. However, the absence of readings or erratic values often point to a faulty sensor.
-
Consult Trouble Codes (If Any): If your check engine light is on, your Autel scanner can read the trouble codes stored in the ECU. Codes like P0335, P0336, or P0339 are common indicators of CPS problems.

Delving Deeper: Addressing Common “How to Check CPS Autel” Queries
Q: Can I test my CPS with an Autel scanner without starting the engine?
A: While you can access live data for the CPS without starting the engine, cranking the engine is often necessary to get accurate readings and trigger potential fault codes.
Q: My Autel scanner isn’t showing any CPS data. What could be wrong?
A: This could indicate a few issues:
- Faulty Connection: Double-check the connection between your scanner and the OBD-II port.
- Blown Fuse: A blown fuse related to the engine management system could disrupt communication.
- Severe CPS Failure: In some cases, a completely failed CPS might not communicate with the scanner at all.
Q: I’m getting erratic CPS readings. Is my sensor definitely bad?
A: Not necessarily. While erratic readings often point to a faulty CPS, other factors like wiring issues, a damaged crankshaft reluctor ring, or even a loose connector can contribute to inconsistent signals.
