The connection between power steering and your check engine light

A check engine light on your 2008 Honda Accord can come from dozens of sources, but a failing power steering pump is one that often gets missed. The power steering system connects to your engine's computer through a pressure switch and flow sensor. When the pump wears out or the fluid level drops, these sensors send a signal to the engine control module, which triggers the check engine light—even though nothing is technically wrong with the engine itself.

The 2008 Accord's power steering pump is driven by a serpentine belt and pressurizes fluid to make steering easier. As the pump ages, internal seals wear, the pump cavitates (draws air instead of fluid), or the pressure relief valve sticks. Any of these failures can cause the computer to log a code related to power steering pressure or flow, which shows up as a check engine light on your dashboard.

Key Takeaways

  • A check engine light paired with stiff steering or whining noises usually points to power steering pump failure rather than an engine problem.
  • The 2008 Accord's power steering pump can fail due to worn seals, low fluid level, or a stuck pressure relief valve, all of which trigger sensor codes.
  • You need a diagnostic scan to read the specific code—P0517, P0518, or codes in the C-series range are common for power steering issues on this model.
  • Replacing the pump typically costs between $400 and $700 in labor and parts, depending on whether you also need a new serpentine belt or hose work.
  • Checking your power steering fluid level and condition is the first step before assuming the pump itself has failed.

Symptoms that point to power steering pump trouble

The check engine light is rarely the only sign. Most owners notice at least one other symptom before the light appears. Stiff steering—especially when turning at low speeds or when the car first starts—is the most common complaint. The steering wheel becomes noticeably harder to turn, and the effort does not decrease as the engine warms up the way it normally would.

A high-pitched whining or squealing noise from the engine bay, particularly when you turn the wheel or accelerate, is another red flag. This noise comes from the pump cavitating—pulling air instead of fluid because the pressure has dropped. Some owners also report a burning smell near the engine, which happens when the power steering fluid overheats due to the pump working harder to compensate for internal wear.

Leaking fluid under the car, especially a reddish or pink puddle, suggests the pump seals are failing. Even a small leak can lower the fluid level enough to trigger the pressure sensor and set the check engine light. If you see any combination of these symptoms plus the light, the power steering system is almost certainly the source.

Reading the diagnostic code to confirm the problem

A diagnostic scan tool is the only way to know for certain what triggered your check engine light. You can borrow or purchase an inexpensive code reader (around $25 to $50), or visit a parts store—many read codes for free. Plug the scanner into the OBD-II port under the steering column on the left side of the dashboard, and it will display the code.

For power steering issues on the 2008 Accord, watch for codes like P0517 (power steering pressure switch low), P0518 (power steering pressure switch high), or codes in the C-series range (C1xxx codes relate to the ABS and power steering control module). If you see one of these, the power steering system is the culprit. If the code is something else—like P0300 (random misfire) or P0171 (system too lean)—the check engine light is coming from the engine itself, not the steering pump.

Write down the exact code before you talk to a mechanic. This saves time and prevents unnecessary testing. Some shops will charge a diagnostic fee; others will waive it if you bring them the code and decide to have them do the repair.

Checking power steering fluid before replacing the pump

Before you assume the pump has failed, check the fluid level and condition. The 2008 Accord's power steering reservoir is a translucent plastic tank on the driver's side of the engine bay, near the firewall. The tank has minimum and maximum marks on the side. The fluid should be bright red or pink; if it is dark brown or black, it has been overheated or contaminated.

If the level is low, top it off with Honda power steering fluid (or equivalent Dexron II ATF, which the Accord uses). Wipe the dipstick or filler cap with a clean cloth before checking—dirt in the system can damage the pump further. After topping off, start the engine and turn the wheel lock to lock a few times to circulate the new fluid. If the light goes out within a day or two of driving, low fluid was the problem.

If the fluid level is full and the light remains on, or if the fluid is dark and the level keeps dropping, the pump itself is failing and needs replacement. Do not ignore a dropping fluid level—running the pump dry will destroy it completely and may damage the steering rack.

What replacement costs and what the job involves

A new power steering pump for the 2008 Accord costs between $150 and $300 depending on whether you choose OEM (Honda) or aftermarket. Labor typically runs $250 to $400 at an independent shop, though dealer rates are higher. Some shops bundle the job with a serpentine belt replacement (which is smart preventive maintenance since the belt drives the pump) or a power steering fluid flush, which adds $100 to $150.

The job itself takes two to four hours. The mechanic removes the serpentine belt, disconnects the pressure and return hoses, unbolt the pump from its bracket, and installs the new one. The hoses are inspected for cracks or leaks; if either hose is damaged, it must be replaced too. After installation, the system is bled of air and refilled with fresh fluid.

If you are handy, this is a job you can do yourself with basic tools and a jack, though you will need a way to dispose of the old fluid responsibly. Many auto parts stores accept used power steering fluid for free. If you go the DIY route, budget extra time for bleeding air from the system—trapped air will cause noise and poor steering feel.

When to replace the serpentine belt at the same time

The serpentine belt drives the power steering pump, alternator, water pump, and air conditioning compressor. If your belt is more than five years old or shows cracks, fraying, or glazing, replace it when you replace the pump. The belt costs $30 to $80, and labor is minimal since the mechanic is already removing it to access the pump.

Replacing the belt at the same time prevents a second breakdown a few months later. Many shops recommend this as routine maintenance on a 2008 Accord, especially if the original belt is still in place. Ask your mechanic to inspect the belt during the diagnostic phase—if it looks worn, factor a belt replacement into your estimate.

Preventing power steering pump failure on older Accords

Power steering fluid degrades over time, especially in older cars that have never had a flush. Dark, burnt-smelling fluid accelerates pump wear. Changing the fluid every 50,000 to 100,000 miles keeps the pump lubricated and extends its life. This is not a factory-recommended service on the 2008 Accord, but many independent shops offer it as preventive maintenance for around $100 to $150.

Keep the serpentine belt in good condition and check the power steering fluid level monthly. A small leak caught early is much cheaper to fix than a failed pump. If you hear whining or notice stiff steering, do not wait for the check engine light—have the system inspected right away. Catching these problems early often means a hose replacement or fluid top-off instead of a full pump replacement.

Frequently Asked Questions

Can I drive my 2008 Accord with the check engine light on if the power steering still works?

You can drive it, but not safely for long. If the power steering is working now, it is failing—the light would not be on otherwise. The pump can fail completely without warning, leaving you with no power steering information. This is dangerous at highway speeds or in heavy traffic. Have it diagnosed and repaired within a few days.

What does it mean if the power steering fluid is dark brown?

Dark fluid means it has been overheated or contaminated with debris from internal wear. This is a sign the pump is already damaged. A fluid flush alone will not fix it—the pump needs replacement. Continuing to drive with dark fluid will accelerate the damage and may harm the steering rack as well.

Is the power steering pump the same on all 2008 Accords?

The pump is the same on all 2008 Accord sedans. The coupe uses the same pump as well. Make sure your mechanic orders the correct pump for your engine size (2.0L or 3.0L), as they are not interchangeable. Always confirm the part number before installation.

How long does a power steering pump last on a 2008 Accord?

Most pumps last 100,000 to 150,000 miles if the fluid is kept clean and the serpentine belt is in good condition. Neglected fluid or a worn belt can cause failure as early as 80,000 miles. Regular fluid checks and belt inspections extend the pump's life significantly.

Will the check engine light go away on its own after I replace the pump?

No. After the pump is replaced and the system is bled and refilled, the mechanic must clear the code using a diagnostic scanner. The light will not turn off automatically. Some shops clear it as part of the repair; others charge a small fee. Confirm this is included before you approve the work.
