P24CA — Particulate Matter Sensor Temperature Circuit Intermittent

What Does P24CA Mean?

P24CA is a diagnostic trouble code indicating: Particulate Matter Sensor Temperature Circuit Intermittent. This code relates to the powertrain system. The vehicle's computer detected a condition outside normal operating parameters and stored this code.

Symptoms of P24CA

⚠️ Check Engine Light (MIL) illuminated
⚠️ Particulate Matter Sensor Temperature signal cutting in and out
⚠️ Related system working sometimes but not consistently
⚠️ Reduced engine performance

Common Causes

🔍 Loose or intermittent connection at Particulate Matter Sensor Temperature
🔍 Wire chafing causing intermittent contact
🔍 Particulate Matter Sensor Temperature failing under heat or vibration
🔍 Corroded connector pins with partial contact

Frequently Asked Questions

What does P24CA mean?

P24CA indicates: Particulate Matter Sensor Temperature Circuit Intermittent. The vehicle's computer has detected that the Particulate Matter Sensor Temperature is not operating within its expected parameters and stored this diagnostic trouble code.

Can I drive with code P24CA?
