When is the p0480 Chevrolet cooling fan relay control circuit detected?

Most auto repairs shops charge between $75 and $150 per hour. When is the P0480 CHEVROLET code detected? The P0480 code is detected when the Powertrain Control Module (PCM) detects that the commanded state of the driver and the actual state of the control circuit do not match. P0480 CHEVROLET Possible Symptoms

When is the p0480 control circuit code detected?

The P0480 code is detected when the Powertrain Control Module (PCM) detects that the commanded state of the driver and the actual state of the control circuit do not match. The PCM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.

What’s the difference between p0480 and P0 482?

NOTE: P0480 speaks of the basic circuit, however codes P0481, and P0482 relate to the same problem with the only difference is they relate to the different fan speed relays. Check engine light (malfunction indicator lamp) illumination and code P0480 set

How much does it cost to repair a p0480 Chevy?

The cost of diagnosing the P0480 CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.

Why does my van have a p0480 code?

Our van – with 103k miles now – brought up a code P0480 last Spring (at about 100k miles), it’s the cooling fan relay circuit error, so I ordered and replaced the cooling fan relay with the Mopar replacement part in June. Within a day, the code reappeared (after I cleared it with a scan tool). It would occasionally go away, and then come back.

How does the p0480 cooling fan relay work?

The PCM (powertrain control module) senses the increase in engine temperature through the CTS (coolant temperature sensor) located near the thermostat. When the temperature reaches about 223-degrees F (value depends on make/model/engine), the PCM will command the cooling fan relay to turn on the fan.

When do I get a p0480 code on my ECM?

The P0480 code is detected when the Engine Control Module (ECM) detects that the commanded state of the driver and the actual state of the control circuit do not match. P0480 DODGE Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) Engine overheating P0480 Dodge Description

When does the pcmcontrol turn on the cooling fan?

The PCMcontrols the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. The cooling fan relay will be commanded ON when the following conditions are met: – The engine coolant temperature reaches 106°C (223°F) or more. – The A/C clutch requested. – The vehicle speed is less than 38 MPH.

What does p0480 mean on a cooling fan?

All our repairs are backed by our 12-month / 12,000-mile warranty. P0480 is a general OBD2 trouble code that refers to the a malfunction within the cooling fan control circuit. This code is similar to P0481 and P0482 codes. P0480 means that the cooling fan 1 control circuit has a malfunction.

What is the diagnostic code for cooling fan 1?

P0480 is a diagnostic trouble code (DTC) for “Cooling Fan 1 Control Circuit Malfunction”.

What causes a faulty fan control relay 1?

Potential Causes. The causes for this DTC may include: Faulty fan control relay 1. Fan control relay harness is open or shorted. Circuit electrical connections poor. Faulty cooling fan 1. Faulty coolant temperature sensor. Fan cooling fan harness is open or shorted.

Where are the cooling fan relay fuses located?

Open the fuse block and inspect the cooling fan relay fuses. If they are good pull the cooling fan relays out. The bottom of the fuse block lid will usually indicate placement, but if not, look in the owner’s manual. The vehicle’s PCM’s function is to act as a ground to operate components, not to supply power.
