Chrysler Error Code P1490: How to Fix It

Q: What causes Chrysler P1490 error code?

P1490 is typically caused by a faulty cooling fan resistor, damaged wiring in the low speed fan circuit, a bad cooling fan relay, or issues with the PCM's fan control output.

Q: Can I drive with P1490 code?

You should avoid driving with P1490 code as it can lead to engine overheating. The high speed fan may still work, but without low speed operation, your engine may run hotter than normal in stop-and-go traffic.

Q: How much does it cost to fix P1490?

Repair costs vary from $50-100 for a relay or resistor replacement to $200-400 for fan motor replacement. PCM replacement can cost $500-1000 including programming.

Q: Is P1490 the same as P0480?

No, P1490 is Chrysler-specific for low speed fan control circuit issues, while P0480 is a generic code for cooling fan 1 control circuit malfunction.

Abstract

Chrysler error code P1490 indicates a problem with the low speed fan control circuit, which controls your engine's cooling fan at low speeds. This issue can cause overheating problems and should be addressed promptly to prevent engine damage.
