The most common cause of a P0523 code on a Chevy Silverado is a faulty engine oil pressure sender. The pressure sender is a 5V circuit that monitors engine oil pressure.

When this component malfunctions, your engine will lose oil pressure, causing an engine failure. In such a case, the oil pressure gauge may not work properly and can cause a Check Engine Light to illuminate.


The P0523 code on a Chevy Silverado means the oil pressure sensor is reading higher than the normal operating range. This condition will typically indicate a problem with the oil system, such as bad or faulty wiring.

You can also check the level and viscosity of oil. The incorrect viscosity may cause the code to display. These are some of the most common causes of the P0523 code on a Chevy Silverado.

A malfunctioning oil pressure sensor can cause the code to display. The oil pressure sensor bolts into the engine and relays a reading to the PCM.

The sensor then converts the mechanical pressure reading into a voltage value that tells the PCM that the oil pressure in the engine is too high.

A low input value will result in a P0523 code. If you encounter the P0523 code on a Chevrolet Silverado, you should not attempt to drive the vehicle until you can confirm that the oil pressure is low.

The first cause of the P0523 code is an issue with the engine oil pressure sensor. This sensor is on a five-volt circuit, which means it is not receiving the correct signal from the engine oil pressure sensor.

When your Chevrolet Silverado displays P0523, you should take it to a mechanic for further examination. This trouble code means that the oil pressure sensor has detected an abnormal signal that is higher than its normal operating range.

Several reasons can cause this code, but the most common problem is a faulty oil pressure sensor. Ultimately, if you do not correct this problem, your engine can fail.

This diagnostic trouble code is a generic trouble code and is common for most vehicles. While symptoms are similar in all vehicles, the methods to diagnose this code vary between vehicles.

If you’re a do-it-yourselfer, it’s a good idea to consult a repair manual or an online subscription service for additional information.

First, check the oil level. Make sure the oil isn’t dirty or expired. Also, test the oil pressure sensor wiring. This part is often susceptible to wiring failure because of its location near the exhaust.

You should check the sensor’s wiring for any signs of damage or missing wiring. You can also test it with a simple multimeter. If the sensor is still showing a high value, replace it.

If this code is accompanied by the Check Engine Light, you may have an oil pressure sensor issue. If the sensor is faulty, oil pressure will eventually be unable to reach the engine.

If this happens, the engine may fail. You should seek immediate repair by a qualified mechanic. Check if technical service bulletins are applicable to your vehicle. Otherwise, contact a dealership to repair the problem.

Mistakes to make

If you are experiencing a troubleshooting issue on your Chevrolet Silverado, then you should know what causes this trouble code. The most common culprit is a bad oil pressure sensor.

Other potential causes include a faulty oil pump and a blocked oil passageway. To determine the exact cause of this trouble code, you can purchase an oil pressure test kit. These kits are mechanical oil gauges and can be used on most makes.

Checking the oil level is the most basic step to solving this problem. You should make sure that the oil isn’t too old and is the right viscosity. In some cases, wiring failure can also be the culprit.

Since oil pressure sensors are located close to the exhaust, they can be damaged or have worn wiring. If you notice wiring damage or the oil pressure sensor has failed, you can easily test it using a simple multimeter.

One mistake to make when driving a p0522 Chevrolet Silverado is ignoring the code. This particular code means that your Oil Pressure Sensor is faulty.

Testing this sensor is the best way to determine if this is the cause of the problem. If you can’t find it, you’ll need to purchase a special socket and a scan-tool.
