2009–11 Models: Complete the diagnosis procedure and if necessary, update the PCM software and replace the affected spark plugs. If the vehicle returns after the updated PCM software and spark plug replacement have been installed, clean the pistons and replace the pistons rings along with the spark plugs (Procedure B).
NOTE: Make sure the software update has been completed, spark plugs replaced (Procedure A), and the vehicle returned to the customer before making any additional repairs. Failure to do so will result in claim review by your DPSM and possible debit.
American Honda is announcing a powertrain warranty extension as a result of a settlement of a class action captioned, Soto et al.v. American Honda Motor Co., Inc., Case No. 3:12-cv-1377-SI (N.D. Cal.).
The piston rings on certain cylinders may rotate and align, which can lead to spark plug fouling. This can set DTCs P0301 No. 1 cylinder misfire detected, P0302 No. 2 cylinder misfire detected, P0303 No. 3 cylinder misfire detected, P0304 No. 4 cylinder misfire detected, and cause the MIL to come on.
American Honda is extending the powertrain warranty to cover repairs related to engine misfire (that triggers DTCs P0301 through P0304) to 8 years with unlimited mileage from the original date of purchase and has settled a class action based on this remedial measure.
This warranty extension does not apply to any vehicle that has ever been declared a total loss or sold for salvage by a financial institution or insurer, or has a branded or similar title under any state’s law.
Owners of affected vehicles were sent a class action settlement notice regarding this warranty extension starting in October 2013.
Before doing work on a vehicle, verify its eligibility by doing an iN VIN status inquiry.
Refer customers seeking information about settlement benefits to www.enginemisfiresettlement.com, or instruct them to call 888-888-3082.
- Connect the HDS and check for the following DTCs: P0301 No. 1 Cylinder Misfire Detected, P0302 No. 2 Cylinder Misfire Detected, P0303 No. 3 Cylinder Misfire Detected, P0304 No. 4 Cylinder Misfire Detected.

Piston Cleaning and Ring Replacement Procedure
- Spray the piston head and piston ring grooves thoroughly with Honda throttle plate cleaner.
- While holding the piston upright in your left hand, take the piston ring groove cleaner tool in your right hand and line up the cleaner tool guides with the second (middle) piston ring groove.
- Press the handle on the piston ring groove cleaner tool and slide the cleaning bit onto the appropriate piston ring grooves.
- Once the cleaning bit is in the appropriate ring grooves of the piston, make sure the tool handle clicks into place.
NOTE: There is only one notch on the tool for the handle to engage.
- Hold the piston steady and rotate the tool counter-clockwise five to six times to remove any carbon deposits in the piston ring grooves. Do not rotate the tool clockwise.
NOTE: You can watch this procedure in the Tech2Tech segment “How to Clean Piston Ring Grooves”.
- Remove the piston groove cleaning tool and clean off the carbon from the tool bit.
- Finish cleaning the piston with throttle plate cleaner and the nylon brush. Do not use a steel wire brush.
NOTE: Below are some examples of before and after pictures. Depending on mileage and running conditions, the pistons will achieve different levels of cleanliness.
- Install the piston rings as shown.
NOTE: The first (top) ring has a 1D manufacturing mark and the second (middle) ring has an SPR manufacturing mark.
The manufacturing marks must be facing upward.
- Position the ring end gaps as shown.
NOTE: If the ring gaps are not positioned correctly, excessive blowby may occur.
- Apply new engine oil to the piston, the inside of the piston ring compressor, and the cylinder bore.
- Install the piston/connecting rod assembly into the cylinder bore with the arrow on top of the piston facing the timing belt side of the engine.
NOTE: Be careful not to damage the cylinder wall when installing the piston.
- Measure the diameter of the connecting rod bolts to determine if they need replacement. Calculate the difference in diameter between point A and point B. It should not be more than 0–0.1 mm (0–0.004 in).
- Apply new oil to the connecting rod bolt threads and flanges. Torque the bolts to 20 N•m (14 lb-ft) then tighten the connecting rod bolts an additional 90 degrees.
- Reinstall the remaining components in the reverse order of removal.
- Replace spark plugs 1–4.
- Replace the oil filter and refill all fluids.
- Do the idle learn procedure.
American Honda Motor Co., Inc. offers SAE J2534 compliant reprogramming software for Honda and Acura vehicles FREE of charge. This J2534 software, when used with a properly built J2534 pass-thru device , will automatically check for the latest vehicle calibration information.
Do NOT program a control module unless you are directed by a service procedure or an applicable Honda/Acura Service Bulletin. Control Module updating should only be undertaken by a skilled professional using proper equipment and procedures, or module damage can occur. The process of updating to the latest software not associated with a specific symptom may not resolve other specific customer concerns. Unauthorized or self-directed programming may cause unintended and irreversible effects and lead to vehicle harm and/or customer dissatisfaction.
American Honda urges end users to always use the LATEST production release of the J2534 Honda Reprogramming software. Using the latest version of the software is the best way to ensure successful reprogramming of applicable control modules.
It is possible to damage the vehicle’s electronic control modules during reprogramming. Ensure the following conditions are met BEFORE programming a control module:
- The vehicle battery must be fully charged before programming the control module. Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming.
- Turn OFF or disable any system that may put a load on the vehicle battery.
- Make certain all tool connections are secure. Do NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
THE ON-SCREEN REPROGRAMMING PROCEDURE MUST BE FOLLOWED EXACTLY AS OUTLINED BY THE SOFTWARE. FAILURE TO FOLLOW THESE INSTRUCTIONS WILL CAUSE THE REPROGRAMMING TO FAIL.
Some modules may require additional programming/setup events performed before or after programming. Please refer to the appropriate Service Bulletins for details. (e.g. IMA Battery Module)
The information in Service Bulletins is intended for use by trained, professional technicians with the knowledge, tools, and equipment to do the job properly and safely. The procedures should not be performed by “do-it-yourselfers”. American Honda reserves the right to supersede this information with updates. The most recent information is available through American Honda’s on-line technical resources.
