P0757 on 2008-2012 Honda Accord: Shift Solenoid 'B' Stuck On Causes and Fixes

What's Unique About the 2008-2012 Honda Accord

For the eighth-generation Honda Accord, the diagnostic procedure is straightforward. Honda's official service documents emphasize checking the automatic transmission fluid (ATF) condition first. Technicians are instructed to drain the fluid through a strainer to look for metal debris, as this indicates a more severe internal transmission failure that would not be solved by replacing just the solenoid. This highlights the importance of fluid maintenance on these transmissions. Shift Solenoid 'B' is not a standalone part but is integrated into the Dual Linear Shift Solenoid assembly (OEM P/N 28260-R90-004), which also contains other solenoids.

Symptoms You May Notice

• Harsh, jerky, or delayed gear shifts.
• Transmission gets stuck in a single gear or fails to shift.
• Vehicle enters 'limp mode' with reduced power.
• Check Engine Light is on.
• Flashing 'D' (Drive) indicator light on the dashboard.
🎬 Watch: Why the D light flashes and how to fix it.
• Increased fuel consumption.
• Transmission may feel like it's slipping.

Most Likely Causes

1. Low or Dirty Automatic Transmission Fluid (ATF) 🔴 High Probability Fluid level and condition are critical for the proper hydraulic operation of Honda transmissions. Over time, fluid breaks down and can become contaminated with clutch material, causing solenoids to stick.
   How to confirm: Check the transmission fluid level on the dipstick when the engine is warm and off. Note the fluid's color and smell; it should be red and not smell burnt. The official Honda procedure involves draining the fluid through a strainer to inspect for debris.
   Typical fix: Perform a transmission fluid drain and fill using Honda-specific ATF DW-1. If significant debris is found, the transmission may need to be rebuilt or replaced.
   Est. part cost: $40-$80 for fluid
2. Failed Shift Solenoid 'B' (Dual Linear Solenoid Assembly) 🟡 Medium Probability Solenoids are electro-mechanical parts that can fail either electrically (coil burns out) or mechanically (plunger gets stuck from debris or wear).
   How to confirm: After confirming fluid is okay, a technician can use a diagnostic tool (like Honda HDS) to command the solenoid on and off while listening for an audible click. The solenoid's resistance can also be tested with a multimeter to check for an open or shorted coil. A common specification for Honda shift solenoids is 12-25 Ohms. No click or an out-of-spec resistance reading indicates a failed solenoid.
   Typical fix: Replace the faulty dual linear shift solenoid assembly. It is located on the exterior of the transmission case, making it accessible without removing the transmission.
   Est. part cost: $100-$250
3. Clogged Transmission Filter or Passages ⚪ Low Probability Debris from normal wear can accumulate and restrict fluid flow, preventing solenoids and valves from operating correctly.
   How to confirm: This is typically found during a fluid service when inspecting the old fluid and the in-pan filter for excessive sludge or metal particles.
   Typical fix: Replacing the transmission filter and performing a fluid flush. In severe cases, the valve body may need to be removed and cleaned.
   Est. part cost: $20-$50 for a filter

Rare But Worth Checking

• Internal Transmission Failure: If metal shavings or significant clutch material are found in the transmission fluid, it's a strong indicator of worn clutches or other internal hard-part damage. In this case, simply replacing the solenoid will not fix the root problem and a transmission rebuild or replacement is likely necessary.
• Faulty Transmission Control Module (TCM) or Wiring: While uncommon, damaged wiring between the TCM and the solenoid, or a failed driver circuit within the TCM itself, can cause this code. This should only be considered after the fluid and solenoid have been ruled out. A visual inspection of the harness for corrosion or damage is a key step. A poor ground connection at G101 (located on the left side of the engine for L4 models, or right front for V6) can also cause intermittent electrical issues.

Diagnosis Steps

1. Check the automatic transmission fluid (ATF) level and condition. Top off if low.
2. If the fluid is dark, burnt, or has particles, perform a drain and fill with Honda-specific ATF DW-1. It is highly recommended to drain the fluid through a fine mesh strainer to check for metal debris.
3. If significant metal debris is found, the transmission likely has internal damage and may need to be rebuilt or replaced.
4. If the fluid is clean and the code returns, locate the Dual Linear Shift Solenoid assembly on the exterior of the transmission case.
5. Inspect the wiring harness and connector going to the solenoid for any signs of damage, corrosion, or loose connections.
6. Use a professional scan tool (like Honda HDS) to activate Shift Solenoid 'B'. Listen for a distinct 'click'. If no click is heard, the solenoid is likely bad.
7. If a scan tool is unavailable, remove the solenoid assembly. Test the resistance of the 'B' solenoid with a multimeter. Compare the reading to the manufacturer's specification (typically 12-25 Ohms). An out-of-spec reading confirms a bad solenoid.
8. If the solenoid clicks and tests good electrically, the issue may be an internal blockage in the valve body or an intermittent electrical problem.
9. If all else fails, the problem may lie within the transmission valve body or, rarely, the TCM itself.

Related Codes That Often Appear With This One

• P0756 — This code is for 'Shift Solenoid B Stuck Off'. It's the opposite fault for the same component and may appear intermittently if the solenoid is failing electrically or mechanically.
• P0700 — This is a generic transmission fault code, indicating that the Transmission Control Module (TCM) has stored a specific fault code (like P0757). It often appears alongside more specific transmission codes.
• P0741 — This code for 'Torque Converter Clutch Circuit Performance or Stuck Off' can sometimes appear with other transmission codes if fluid degradation or debris is affecting multiple components, like the TCC solenoid and the shift solenoids.

Mechanic-Grade Diagnostic Values

• Shift Solenoid 'B' Coil Resistance — expected: 12 - 25 Ohms. Failure: A reading of 0 Ohms (short circuit) or infinite/OL (open circuit) indicates a failed solenoid coil.
• A/T Clutch Pressure Control Solenoid Valve B Resistance (part of the same assembly) — expected: 3 - 10 Ohms. Failure: A reading outside this range indicates a failure in that specific part of the solenoid assembly.

Scan Tool Commands That Help

• Honda Diagnostic System (HDS): Shift Solenoid Valve B Test (found in the Miscellaneous Test Menu) — This bidirectional command allows a technician to manually activate the solenoid. A distinct 'click' should be heard, confirming the solenoid is mechanically and electrically responding to the command. No click points to a failed solenoid or a wiring issue.

Wiring & Ground Locations

• G101 (L4 Engine) — On the left side of the engine.. This is a primary ground point for the engine and transmission components. A loose or corroded connection here can cause erratic voltage and unpredictable behavior from electronically controlled parts like shift solenoids.
• G101 (V6 Engine) — On the right front of the engine.. Similar to the L4 engine, this is a critical ground point. Ensuring it is clean and tight is a crucial step in diagnosing any electrical fault in the transmission system.
• Dual Linear Solenoid Connector — On the exterior of the transmission housing, often visible under the battery tray area.. This is the direct electrical connection to the solenoid assembly. It should be inspected for corrosion, bent pins, or a damaged locking tab, as a poor connection can mimic a failed solenoid. The connector harness has two wires.

Real Owner Repair Stories

• Honda Accord Forum (2012 Honda Accord 2.4 SE) — Flashing 'D' light, check engine light on, transmission would suddenly stop shifting (act like it was in Neutral) at highway speeds (70 mph) and also at lower speeds in 3rd gear.
  ❌ Tried (didn't work) The owner removed the solenoid assembly (P/N 28260-R90-004) and tested it. The resistance measured 6 ohms (within the 3-10 Ohm spec for that part of the assembly) and the solenoids clicked when 12V was applied, indicating the part was likely good.
  ✅ What actually fixed it The owner noted that the connector itself was damaged. After reinstalling the original solenoid with a new gasket and presumably repairing or securing the connector, the issue was resolved. This highlights that the wiring/connector can be the fault even if the solenoid tests good.

OEM Part Supersession History

• Not specified, but multiple revisions exist. → 28260-R90-004 — Standard part evolution and updates.
  Heads up: The part 28260-R90-004 is listed as compatible for the entire 2008-2012 generation (and up to 2015 for some models), indicating good backward compatibility.

Model Year Variations Within This Range

• 2011-2012: For the 2011 model year facelift, Honda made revisions to the five-speed automatic transmission, primarily to improve fuel economy. While the core components like the solenoids remained the same, internal gear ratios and TCM software logic may differ slightly from the 2008-2010 models.
• 2008-2012: The V6 models use a different engine (J35Z series) and have different ground point locations (G101 is on the right front) compared to the 4-cylinder models (K24Z series, G101 on the left side). While they share the same 5-speed automatic transmission and P0757 code, the physical layout for diagnosis differs.
