P0322 Fault Code

Ignition/Distributor Engine Speed Input Circuit No Signal

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0322 fault code indicates that there is no signal from the ignition or distributor engine speed input circuit. This code can arise in various vehicle systems that rely on the engine speed input for proper operation. When the engine control module (ECM) detects a lack of input signal from the crankshaft position sensor or camshaft position sensor, it triggers this code.

What are the symptoms of the P0322 code?

• Check Engine Light (CEL) is illuminated
• Engine may not start or has difficulty starting
• Rough idle or engine stalling
• Poor acceleration or performance issues
• Possible fluctuations in engine RPM while driving

What causes the P0322 code?

• Faulty crankshaft position sensor
• Damaged wiring or connectors in the speed input circuit
• Failed camshaft position sensor
• Problems with the engine control module (ECM)
• Poor connections or ground issues in the ignition system

How to fix P0322?

• Inspect and replace the crankshaft or camshaft position sensor if faulty
• Check and repair any damaged wiring or connectors in the input circuit
• Ensure good ground connections and clean any corrosion
• Test the engine control module for proper functionality and replace if necessary
• Clear fault codes and perform a test drive to ensure the issue is resolved
