What P0322 means
P0322 means the speed and reference input of the ignition – today the crankshaft position sensor – delivers no signal although the engine is turning. Ford proves the rotation with the camshaft sensor: if it shows more than one engine revolution without a crank signal (from 500 rpm, detected within 5 s), Ford sets P0322 or, depending on the engine, P0335; with electronic throttle the throttle software adds P2106 and goes into limp mode. Without a crank signal there is no ignition or injection, so the engine stalls or does not start. Saab's Motronic 2.8.1 (900 V6) sets P0322 when the engine fails to start; its inductive sensor should measure 500–600 Ω and give 2–5 V AC while cranking. Systems without a camshaft-based check may store no code at all on a total failure.
P0322 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0322
- Engine cranks but does not start
- Engine stalls while driving
- Tachometer shows zero
- Check engine light on, with electronic throttle limp mode (P2106)
Common causes of P0322
- Most likelyCrankshaft position sensor failed (often heat-related)
- Most likelyOpen or short in signal, ground or 5 V supply, corroded connector
- PossibleSensor loose, air gap too large or tone wheel damaged
- Less likely5 V reference pulled down by another sensor on the same supply
- Less likelyEngine module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0322 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 3 | Area: ignition system or misfire. |
| 22 | The exact fault in that area. |
What to do next
- Note P0322 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0322
What does P0322 mean?
P0322 means "Ignition/Distributor Engine Speed Input Circuit No Signal". P0322 means the speed and reference input of the ignition – today the crankshaft position sensor – delivers no signal although the engine is turning. It is a generic code, so it means the same on every make.
Is it safe to drive with P0322?
Drive gently and only to a workshop. With P0322 the car can go into limp mode (reduced power) to protect itself.
Will P0322 fail an emissions test?
Yes, it can. P0322 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0322 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0322 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
