P0776 on 2012-2016 Honda CR-V: Pressure Control Solenoid 'B' Fixes

What's Unique About the 2012-2016 Honda CR-V

On this generation of Honda CR-V (specifically the 2012-2014 models with the 5-speed automatic), the transmission solenoids are often mounted externally in packs, making them more accessible than on many other vehicles where they are located inside the transmission oil pan. This design simplifies diagnosis and replacement, often making it a feasible DIY job. The issue is frequently resolved by replacing the solenoid and changing the fluid, without needing more invasive transmission work.

Symptoms You May Notice

• Harsh or jerky shifting, especially between lower gears
• Delayed gear engagement
• Transmission slipping between gears
• Inability to shift into higher gears (stuck in a low gear)
• Flashing 'D' (Drive) indicator light on the dashboard
• Illuminated Check Engine Light
• Vehicle entering 'limp mode' with reduced power
• Transmission overheating
• Decreased fuel economy

Most Likely Causes

1. Faulty Pressure Control Solenoid 'B' 🔴 High Probability → Shop Transmission Valve Body Solenoids are wear-and-tear items that can fail electrically or mechanically over time. Debris in the fluid can cause them to stick, preventing proper hydraulic pressure regulation.
   How to confirm: A mechanic can use a high-end scan tool to command the solenoid on and off while monitoring transmission pressures. Resistance can also be checked with a multimeter across the solenoid's terminals; an open or shorted reading indicates a failed solenoid.
   Typical fix: Replace the A/T Clutch Pressure Control Solenoid Valve assembly. 🎬 Watch: Diagnostic guide for the P0776 solenoid code On these CR-Vs, Solenoid 'B' is often sold in a pack with Solenoid 'C'. The specific part is a dual linear solenoid.
   Est. part cost: $100 - $250
2. Low or Contaminated Transmission Fluid 🟡 Medium Probability → Shop Transmission Assembly Fluid breaks down over time and can become contaminated with clutch material. Leaks can also lead to low fluid levels, causing pressure issues and solenoid malfunction. Honda transmissions of this era are known to be sensitive to fluid condition.
   How to confirm: Check the transmission fluid dipstick for level and color. The fluid should be red and clear, not dark brown, black, or smell burnt.
   Typical fix: Perform a transmission fluid drain-and-fill (or multiple) using only Honda Genuine DW-1 ATF. 🎬 Watch: Step-by-step transmission fluid drain and fill Do NOT use a high-pressure fluid flush, as this can dislodge debris and cause further issues.
   Est. part cost: $60 - $150
3. Clogged Transmission Filter ⚪ Low Probability → Shop Transmission Assembly If the transmission fluid has not been changed regularly, the filter can become clogged with debris, restricting fluid flow to the solenoids and valve body.
   How to confirm: This is typically discovered during a fluid change or solenoid replacement. The filter will be visibly dirty.
   Typical fix: Replace the in-line transmission fluid filter. 🎬 Watch: How to change the transmission fluid and filter
   Est. part cost: $20 - $50

Rare But Worth Checking

• Damaged Wiring or Connectors: The wiring harness leading to the transmission can be damaged by heat or road debris, causing a poor connection to the solenoid. Always inspect the connector and nearby wires for damage before replacing the solenoid.
• Faulty Transmission Control Module (TCM): → Shop Transmission Assembly In very rare cases, the computer that controls the transmission can fail, sending incorrect signals to the solenoid. This should only be considered after all other possibilities have been exhausted.
• Defective Transmission Valve Body: → Shop Transmission Valve Body The valve body contains a network of passages and valves that direct fluid flow. If a passage is blocked or a valve is stuck internally, it can mimic a solenoid failure. This is a more complex and expensive repair.

Diagnosis Steps

1. Check the transmission fluid level and condition. If it is low, top it off with Honda DW-1 ATF and check for leaks. If it is dark or smells burnt, a fluid change is necessary.
2. Use a professional scan tool to check for other transmission-related codes and view live data from the transmission sensors.
3. Inspect the wiring harness and connector going to the pressure control solenoid assembly for any signs of damage, corrosion, or loose connections.
4. Locate the Pressure Control Solenoid 'B' assembly on the exterior of the transmission case.
5. Test the solenoid's resistance with a multimeter. Compare the reading to the manufacturer's specification (typically between 5 and 30 ohms). An open or shorted reading indicates a failed solenoid.
6. If a bi-directional scan tool (like the Honda HDS) is available, command the solenoid on and off to listen for an audible click and monitor pressure changes.
7. If the solenoid is faulty, replace the solenoid pack, gasket, and any associated O-rings.
8. After replacement, perform a transmission fluid drain-and-fill with Honda DW-1 ATF. Some experts recommend multiple drain-and-fills to replace a higher percentage of the old fluid.
9. Clear the trouble code and perform a test drive, allowing the transmission to shift through all gears to confirm the repair.

Parts You'll Likely Need

• A/T Clutch Pressure Control Solenoid Valve Assembly (B/C) (OEM #28260-R90-004) — This is the component that directly causes the P0776 code when it fails electrically or becomes stuck. This part is a dual linear solenoid assembly.
  Trusted brands: Honda (OEM)
  OEM price range: $150-$250
  Aftermarket price range: $80-$150
• Automatic Transmission Fluid (ATF) (OEM #08200-9008 (DW-1)) — Fresh, correct fluid is critical for the new solenoid to operate correctly and for overall transmission health. A drain-and-fill requires approximately 3-4 quarts. Using non-Honda fluid is not recommended.
  Trusted brands: Honda (OEM)
  OEM price range: $12-$18 per quart
• Solenoid Gasket (OEM #28262-R90-003) — The gasket provides a critical seal between the solenoid body and the transmission case to prevent fluid leaks. It should always be replaced with the solenoid.
  Trusted brands: Honda (OEM)
  OEM price range: $10-$20
  Aftermarket price range: $5-$10

Related Codes That Often Appear With This One

• P0777 — This code means 'Pressure Control Solenoid B Stuck On', which is the opposite fault but relates to the exact same component. NHTSA ODI #11645682 notes that on similar Honda platforms, P0776 and P0777 can appear together, leading to recommendations for significant transmission work.
• P0741 — This code relates to the Torque Converter Clutch solenoid. Fluid quality or pressure issues that trigger P0776 can sometimes affect other solenoids as well.

Technical Service Bulletins (TSBs) & Recalls

• Honda TSB 15-086: Notes that some 2012-2014 CR-Vs might experience a judder or vibration under light acceleration. The recommended fix is a PCM software update and a transmission fluid change, indicating the transmission's sensitivity to software and fluid condition.

Mechanic-Grade Diagnostic Values

• Shift Solenoid 'B' Coil Resistance — expected: 13.8 - 17.1 Ohms. Failure: A reading outside of this range (open circuit or short) indicates a failed solenoid coil.

Scan Tool Commands That Help

• Honda Diagnostic System (HDS): Miscellaneous Test Menu -> Shift Solenoid Valve B Test — This is a key diagnostic step to confirm if the solenoid is mechanically functioning. The HDS commands the solenoid to activate, and the technician should listen for an audible 'click'. If no click is heard, it strongly suggests the solenoid is stuck or has failed, justifying its replacement.

OEM Part Supersession History

• 28260-PRP-014 → 28260-R90-004 — Part update or consolidation by the manufacturer.
  Heads up: Both part numbers refer to the same dual linear solenoid assembly and are generally interchangeable for this application. However, it is always best to verify with the VIN.

Model Year Variations Within This Range

• 2012-2014: These models use a 5-speed automatic transmission where the P0776 code directly points to the externally mounted dual linear solenoid (Part No. 28260-R90-004).
• 2015-2016: These models use a Continuously Variable Transmission (CVT). A P0776 code on these vehicles points to an issue with the control valve body or belt/pulley assembly inside the CVT. The repair is significantly more complex and expensive, often requiring specialized tools like a borescope to inspect for internal damage.

Other Known Issues on This Vehicle

Issues unrelated to this code that are worth knowing about as an owner of this generation:

• VTC Actuator Rattle on Cold Start 🟠 Medium — Very common on 2012-2014 models. A loud rattle for 1-2 seconds immediately after a cold start. (Ref: Honda TSB 09-010, TSB 16-012)
• Vibration at Idle or Low Speeds (CVT Models) 🟡 Low — Common complaint on 2015-2016 models with the CVT transmission. Can cause a noticeable shudder or vibration when stopped in gear or during light acceleration. (Ref: Honda TSB 15-046)
• Premature Starter Motor Failure 🟠 Medium — A frequently reported issue across the generation, leading to a no-start condition.
• Parasitic Battery Drain 🟡 Low — Some owners report the battery dying after the vehicle sits for a few days. This has been linked to issues like a stuck A/C relay.
• Oil Dilution (2015-2016 Earth Dreams Engine) 🔴 High — The direct-injected 'Earth Dreams' engine can suffer from gasoline mixing with the engine oil, particularly in cold climates with short-trip driving patterns. This thins the oil and can lead to premature engine wear. (Ref: Honda extended warranty programs and software updates were issued for some models.)

Used vs. New Parts: Buying Guide for This Vehicle

When a used part is the smart pick: A used OEM solenoid from a reputable salvage yard can be a cost-effective option, especially if the donor vehicle has low mileage. Given the high cost of a new OEM part, a tested, used component is a reasonable choice for budget-conscious repairs.

Donor-vehicle mileage cap: roughly under 80000 miles for the part to have meaningful remaining life.

What to inspect on the donor part:

• Ensure the part is a genuine Honda OEM part (look for markings).
• Inspect the electrical connector pins for any signs of corrosion or damage.
• Check the small filter screens on the solenoid body; they should be clean and free of metallic debris.
• Ask the seller if the part has been tested or if it comes with a short-term warranty.

OEM-only on this vehicle (don't cheap out):

• Pressure Control Solenoid Assembly

Brands owners have reported issues with on this vehicle:

• Unnamed/generic brands from online marketplaces are a gamble. Honda transmissions are known to be sensitive, and an aftermarket solenoid with slightly different flow or resistance characteristics can cause persistent shifting issues even if it clears the code initially.
