With Parts Avatar Canada, your one stop destination for hassle free shopping and superior quality parts, we assure you not only the best at rock bottom prices to keep you on a payroll but also to equip you with a straightforward guide to crack the OBD’S. The OBD Code P0529 is a generic diagnostic code that appears when the ECM receives an incorrect voltage signal, in this case an intermittent signal from the electric cooling fan circuit. If the voltage recorded differs more than 10% from the manufacturer’s current voltage levels, a P0529 code is stored. Many vehicle models have sensor at the end of the cooling fan that senses movement while the vehicle is operating. In a vehicle issued with an electric fan, this sensor verifies the fan speed and checks on the detected speed matching with the fan speed commanded by the vehicle’s ECM. The fans generally consist of a primary cooling fan and one or more secondary cooling fans. Most commonly used the single-speed engine cooling fans, but some automakers utilize the fan with multiple speed settings while the others utilize the electro-hydraulic cooling fans that use the voltage and hydraulic pressure. It is advised to check the vehicle service manual for the fan set up and type.

All the engine cooling fans are monitored by the ECM, which uses the data to calculate fan activation and speed. When the engine reaches a current temperature (differs by manufacturer and vehicle make/model), the ECM sends in a signal to the fan relay. Also, the fan relay has constant supply of fused voltage and one or more ground signals from the ECM. Subsequently, the cooling fan relay(s) help take the low voltage (or ground) signal and then further turn it into the signal required for the cooling fan motor to function.

What causes this problem with the Fan Speed Sensor Circuit Intermittent?

• Defective, disconnected, or shortened wirings.
• Faulty cooling fan motor.
• Distorted cooling fan relay.
• Broken or unsound cooling fan speed sensor.
• Loose, burnt or defective electrical connectors.
• Damaged or inaccurate engine coolant temperature sensor.
• In a rare case, a damaged ECM.

1. Engine Coolant Temperature Sensor - Coolant Temperature Sensor is a sensor used to control the temperature of the Engine’ coolant. So, to maintain an optimal temperature, the coolant temperature sensor should be restored/repaired immediately.
2. Fan Clutch - trying to fight the error code P0529? An inferior quality Fan Clutch can always be hazardous for the system also it is one of the primal causes behind the occurrence of the error code P0529. Tune into Parts Avatar for premium quality Fan Clutches at economical prices.
3. Cooling Fan Speed Sensor - The cooling fan speed sensors function to verify the fan speed commanded by the PCM or the ECM. So, a faulty one should be changed as soon as possible in order to combat the complications caused by the Error Code P0529.
4. Fan Speed Sensor Wire - Having problems with the Fan Speed Sensor Wire? Don’t you worry, Parts Avatar has it all. Corroded or shortened Fan speed sensor wires can often end up being the root cause behind the Error code P0529.
5. Fan Speed Sensor Connector - Get your Error Code fixed instantly with new Fan speed sensor Connectors. Parts Avatar is just the right place offering the best fan speed sensor connectors across the country.
6. Cooling Fan - A distorted Cooling fan can end up being the chief host inviting the Error Code P0529. So, replacing one can be one of the wisest decisions to avoid a problematic system.
7. Cooling Fan Motor - trying to mend the Error Code P059? Well, it could be due to a jammed or an unsound Cooling Fan Motor. So, what are you thinking? Get yours changed now from Parts Avatar. We are just a click away, tune in now!
8. Cooling Fan Relay - Facing the Error P0529? Well, get that fixed with a new Cooling Fan Relay at Parts Avatar, available online at the best prices.
9. Fan Belt - looking for a new Fan belt to fight the Error Code P0529? Tune into Parts Avatar for superior quality belts just at the prices you have been looking for.
10. Powertrain Control Module - abbreviated PCM; this is an integral control unit. So, a defective one should be replaced/repaired instantaneously.
11. Engine Control Module - this essential unit can often lead to worsening the Error Code P0529. Get yours changed now to avoid any harmful effects of the Error Code P0529.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P0529 code by mentioning some major symptoms below:

Common Symptoms

• The check engine or warning light appearing on.
• The vehicle may at times fail to display any other symptoms except for a stored trouble code.
• The Engine heating excessively.
• Malfunctioning Air Conditioner.

We have listed out some ways which would help you to correct the occurrence of OBD Code P0529. They are mentioned here as follows:

Many amendments that can fix the P0529 trouble code include:

• All the corroded, defective and disconnected wires and connectors should be replaced or repaired.
• Damaged engine coolant temperature sensor should be restored or repaired.
• Correct the faulty cooling fan speed sensor.
• Mend the unsound engine cooling fan motor.
• The damaged or malfunctioning engine cooling fan relay should be replaced
• In a rare case, replace/restore the distorted ECM.
• Lastly, all the codes should be cleared and the vehicle should be retested to see if the code sets again.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade Engine Coolant Temperature Sensor, Fan Clutch, Cooling Fan Speed Sensor, Fan Speed Sensor Wire, Fan Speed Sensor Connector, Cooling Fan, Cooling Fan Motor, Cooling Fan Relay, Fan Belt, Powertrain Control Module, Engine Control Module, Blown Fuse and a lot more for our precious customers.

• An OBD-II scanner should be used to check for a stored P0529 trouble code.
• Visually verify for any damage in the wiring and components.
• Use a scanner, activate the engine cooling fan and inspect for voltage and ground signals
• Check the system fuses if voltage is absent in engine cooling fan motor.
• Look for engine fan relay, test voltage readings and compare with manufacturer recommendations
• Inspect and test engine temperature
• Verify for broken or damaged engine coolant temperature sensor, and compare the temperature to manufacturer recommended resistance values
• If there is no defect in the primary cooling fan, and if secondary cooling fans are present, check secondary cooling fans for any damage or faults.
• Utilize an RPM to voltage conversion chart to test speed.

Common Mistakes When Diagnosing the P0529 Code

A technician at times might fail to diagnose the problem accurately, so in order to make the diagnose a hassle-free process we have listed here a few common mistakes that should be taken care of while diagnosing the problem.

At times. The cooling fan is replaced instead of the wiring, harnesses or the relays. It is always advised to troubleshoot for any electrical problems before replacing the cooling fan.
