Warranty Extension: MIL Comes On With DTCs P0301 Through P0304
BACKGROUND
American Honda is announcing a powertrain warranty
extension as a result of a settlement of a class
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 through P0304 and cause the MIL to
come on.

DIAGNOSIS
1. Connect the HDS to the vehicle and check for the
following DTCs: P0301, P0302, P0303, P0304.
• If any of these DTCs are stored, go to step 2.
• If none of these DTCs are stored, this bulletin
does not apply. Continue with normal
troubleshooting.
2. Check the PCM software and note if it is earlier
than shown below, then go to step 3 (all 2012 and
2013 vehicles are up to date).

3. Remove and check the spark plug(s) on the
affected cylinders (example: if P0301 is stored,
check the spark plug on cylinder No. 1).
• If the spark plug(s) are not fouled, this bulletin
does not apply. Continue with normal
troubleshooting.
• If this vehicle has any of the above DTCs, the
spark plug(s) are fouled, and the software is an
earlier version, go to REPAIR PROCEDURE A.
• If this vehicle has any of the above DTCs, the
spark plug(s) are fouled, and the software is a
current or later version, go to step 4.
NOTE: Below are examples of good and fouled
spark plugs.

4. Note which DTCs are stored in the vehicle.
• If the vehicle has one or more of the following
stored DTCs: P0301, P0302, P0303, go to
REPAIR PROCEDURE B to clean the pistons,
replace the piston rings on the cylinders 1–3, and
replace the spark plugs on cylinders 1–4.
• If the vehicle has DTC P0304 with or without any
of the other three DTCs stored, go to REPAIR
PROCEDURE B to clean the pistons, replace the
piston rings on cylinders 1–4, and replace the
spark plugs on cylinders 1–4.

2. Spray the piston head and piston ring grooves
thoroughly with Honda throttle plate cleaner.
3. 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.
12 of 15
5. Once the cleaning bit is in the appropriate ring
grooves of the piston, make sure the tool handle
clicks in to place.
NOTE: There is only one notch on the tool for the
handle to engage.
13-082
6. 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”.
NOTE: Below are some examples of before and
after pictures. Depending on mileage and running
conditions, the pistons will achieve different levels
of cleanliness.
7. Remove the piston groove cleaning tool and clean
off the carbon from the tool bit.
8. Finish cleaning the piston with throttle plate cleaner
and the nylon brush. Do not use a steel wire brush.
