How to Diagnose a P069E Chevy Silverado

Fuel Pump Control Module

If you’ve ever received a code reading “Fuel Pump Control Module Requested MIL Illumination”, it’s probably because your Chevy Silverado’s fuel pump is having trouble.

The code is not specific to this vehicle; it applies to any model with an OBD-II scan tool. However, if you get this code in your vehicle, it is a good idea to take it to your mechanic as soon as possible.

Regardless of why you’re seeing the P069E code, you’ll need to diagnose the underlying cause of the problem. In most cases, it’s the fuel pump control module.

However, there are some other issues that might be affecting its performance. Listed below are a few things you can do to troubleshoot this code. This article will walk you through some basic diagnostic tests you’ll need to perform.

Check for good power, ground, and resistance on the fuel pump control circuit. Refer to the wiring diagram or a DVOM to determine what’s wrong with the module.

If the codes are unreadable or the pump is not operating properly, replace the module or reprogram the ECM. If you find no obvious signs of malfunctioning, you may have a more serious problem.

The P069E code is a common sign of a malfunctioning fuel pump controller. It illuminates the Malfunction Indicator Lamp (MIL) when the fuel pump controller is malfunctioning.

When you get this code, you may experience a reduction in engine power or even a no-start condition. The repair will cost anywhere from $100 to $300, depending on the make and model of your vehicle.

Fuel Pump Wire Harness

If you’re experiencing problems with your vehicle’s fuel pump, you should consider installing a new wiring harness. These harnesses can save you money on fuel, and provide reliable performance.

A Racetronix harness features heavy-gauge stranded copper wiring, three to four gauges thicker than the factory wires. The increased thickness decreases resistive power loss, resulting in a 10-20% improvement in pump performance.

The wiring harness also features weatherproof relays and fuse holders, as well as factory-type connectors, enabling you to plug it directly into the fuel pump module with no splicing or modification.

An upgraded wiring harness will increase the fuel pump’s performance by 20% or more, depending on the model. Unlike the factory wiring, Racetronix’s fuel pump wire harness is plug-and-play, removing the added load on the factory wiring harness.

The boosted voltage is delivered to the fuel pump through an intermediate high-current (30 amp) connector, making installation easy.

To troubleshoot the P069E code, check the fuel pump wire harness for any damage or short circuits. Make sure the wire harness is properly inserted, and that there is no openings or shorts in it.

If the wires are still intact, the fuel pump controller may be at fault. You can check these by consulting your vehicle’s information source. The fuel pump wire harness is located on the powertrain control module.

A faulty wiring harness can cause this code to come up in the dashboard’s diagnostic software. To diagnose the P069E code, follow the steps outlined below.

Check the wiring harness for any shorts and traces back to the ECM. If the fuel pump control module is faulty, you may need to replace the ECM or have it reprogrammed.

Intermittent Electrical Fault in The Fuel System

When your Chevrolet Silverado starts with a bogus reading of no fuel, you should investigate the problem. It could be a loose drive belt or worn out alternator. In either case, you should examine the belt for any damage and adjust or align it properly.

Other parts of the fuel system you should inspect are the wiring, fuses, and voltage regulator. A fault with the voltage regulator could lead to intermittent failure of electrical accessories.

In some cases, the vehicle may not run at all and go into limp mode. This problem can also affect the throttle position sensor. Whether or not it is related to this symptom will depend on the particular model.

Some owners have discovered the problem only after they had to take their vehicle to a mechanic. Some people had to learn the hard way and spend hours trying to determine what was causing the failure.

When this problem occurs, the positive battery cable may be the root cause of the issue. If this happens, the positive battery cable could take out individual systems fused in the main fuse box.

This causes power door lock actuators to automatically activate and may be the cause of the intermittent electrical problem on your Chevrolet. If the problem is the ignition switch, the positive battery cable could be the cause.

The best way to determine the source of an intermittent electrical fault is to get a wiring diagram for your vehicle. This diagram will show how components are connected to one another, how power is routed, and how a circuit is grounded.

If you notice multiple instances of an intermittent electrical fault, chances are that you have loose wiring and a faulty fuse. Consequently, if you’re not able to isolate the source, it is unlikely to be the cause.

In a newer Chevrolet Silverado, a failed driver module could be the culprit. This device controls the operation of the fuel pump. It is located in the fusebox, so replacing this part is a fairly simple procedure.

An ignition coil could also be the culprit if your car has multiple cylinders. A failed ignition coil can cause a misfire and can be replaced for around $100.

Cost of Diagnosing a p069e Chevy Silverado

If your vehicle has been giving you trouble for a while, then you may be wondering how to diagnose the problem. This code indicates a fuel pump controller malfunction, and it will cause your vehicle’s Malfunction Indicator Lamp to illuminate.

The symptoms of this code are intermittent and can make your engine run less smoothly or even stall. While you can fix this problem yourself, you may need the assistance of a technician to diagnose the problem correctly.

There are some common causes of this code, including damaged hoses or faulty EVAP purge volume control valves. The fix is simple, and it will cost between $75 and $150.

You can take the vehicle to a certified mechanic for diagnosis. The diagnostic fee is usually applied to the repairs. This will save you money since you’ll be able to estimate the cost of the repairs in advance.

If your vehicle has the same code as yours, there’s a good chance that it’s a catalyst system problem. To make sure that the problem is not related to the catalyst system, bring it to a reputable repair shop for diagnostic work.

If the problem persists, you may need to replace some of the parts. The cost of diagnosing a p069e Chevy Silverado depends on the level of expertise and experience.

Diagnostic cost for a p069e Chevy Silverso varies between $75 and $150 per hour. The diagnosis will determine if the fuel pump control module is functioning correctly.

If the issue persists after the 45-second time frame, the error code will be extended to P069E. This code is also common in many American-made vehicles, including Ford, Buick, and Cadillac.

The cost of diagnosing a p069e Chevy Silverado varies by make, but most auto repair shops charge between $75 and $150 an hour.

Fuel pump voltage can be faulty or activated, which causes the cylinder to overheat and fail to rev. Check the fuel pressure with a mechanical gauge to make sure it’s within spec.

If it’s within spec, it’s likely the problem is with the fuel pressure sensor. Once you’ve identified the issue, the next step is to fix it.
