SOURCE: I got the code P0847

Does it have any shifting problems? Hard shift or slipping? If not you may just need the 3rd clutch pressure switch. It will need to come from Honda I don't know pricing but I would think less then $100 and shouldn't take long to replace.

SOURCE: Stuck in 5th gear

That just recently happened to me. If your stick wont move into any of the gears, then you need a clutch. But if you can shift into the gears but dont go anywhere, then you need a new transmission.

SOURCE: '02 ACCORD 1-2 Shift Shudder,

The shift control solenoid externally mounted on the transmission can fail and causes a harsh 1-2 shift. Replacing the shift solenoid and flushisng the transmission with genuine Honda automatic transmission fluid may eliminate harsh shifting characteristics. A broken internal spring can cause the same issue. If the shift control solenoid does not repair the problem, the transmission will have to be replaced.

In both cases (CR-V and the Civic) there is a linear solinoid that can cause the problem or if not then a broken spring inside the transmission that can create the same issue. The cheapest thing to do is to replace the linear solinoid and flush the transmission. If there is no change then the transmission will need to be replaced. The spring is deep inside the transmission and would require complete disassembly for replacement, and it's ususally more cost effective to replace the transmission as a unit.

Honda has issued a bulletin on this issue. As far as I can recall it's been about 50/50 between the spring and the solinoid to repair the problem. Some customers choose to live with the issue due to the cost involved.

Hope helps.

SOURCE: Location of A/C compressor clutch relay for 2004 Honda CRV

its under the hood in the box near the battery on the drivers side. I believe its the tall black one, but I could be wrong about which one since there are a number of them-- I know its in that box near the battery though.

P1775 code in showing up on my 2008 jeep wrangler x. How do you fix that?


we can not answer what you can do or fix.
only how to diagnose, or is this just a please guess for me post?
got tools, got a real scan tool?
is this a 5 buck code reader that misses most codes.
or a real one (ask for good tools)
if a real tool, it will show all codes, and you must know them all
or go astray. P0841? present? too>?

42RLE box.::: one code only, my guess.

i have this car, (m/t) and full FSM, on it,
Ill decode this and tell you what page to read in the FSM
it shows what to do next and the tests to prove this out.
P= power train
P1 means factory code ( so dont read ford codes)
SOLENOID SWITCH VALVE LATCHED IN TCC POSITION
TCC means torque converter clutch. lock up device. failure.
that means transmission, (id didnt say its bad)
the transmission on your car is automatic, unlike my stick
it has a TCM brain, hidden in the PCM brain
but its real and there. for sure. inside.
and it shifts for you, this brain,. in DRIVE

here is the 1st page on this code. in fsm book.

The Solenoid Switch Valve, an internal, hydraulically operated valve, controls the direction of the transmission
fluid when the LR solenoid is energized. When the solenoid switch valve is in the downshifted position and the
LR solenoid is energized, fluid is directed to the LR element for 1st gear. When the solenoid switch valve is In
the up-shifted position (2nd, 3rd, and 4th gear) and the LR solenoid is energized, fluid is directed into the
Lockup Switch Valve which controls the Torque Converter Clutch. When shifting into 1st gear, a special
sequence is followed to insure solenoid switch valve movement into the downshifted position. The LR pressure
switch is monitored to confirm switch valve movement. If the solenoid switch valve movement is not confirmed
(i.e. no LR pressure when the LR solenoid is energized), 2nd gear is substituted for 1st. No 1st gear (2nd gear is
substituted). The transmission Torque converter FEMCC operation is inhibited. MIL on after 5 min. of
substituted operation.
Monitor Conditions
When Monitored:
Prior to a shift into 1st gear.
possible causes:
RELATED DTC P0841 PRESENT?
(T16) TRANSMISSION CONTROL OUTPUT CIRCUIT OPEN
(T50) L/R PRESSURE SWITCH SENSE CIRCUIT OPEN
(T50) L/R PRESSURE SWITCH SENSE CIRCUIT SHORT TO GROUND
(T50) L/R PRESSURE SWITCH SENSE CIRCUIT SHORT TO VOLTAGE
INTERNAL TRANSMISSION
POWERTRAIN CONTROL MODULE

the book says have the dealer
do a full transmission check using there (unique) fancy tool..
seems to be good advice.

below is the interface tcm.<> box.
solenoid and read back switches.
if the trans is not bad, then this switch is bad (fibbing)
or the wires rusty there... re-seat them yet?

Using the switches also makes the shifting smother and saves fuel.

Honda stream 2009 'D' blinking light. diagnostic says po843 code


take it in, get it fixed ? stream?) not sold here, so alldata.com has nada.
or if DIY person
RTM , read the manual the FSM. its all there, look up 843
it tells you all the tests to do , that isolates the true cause of failure.

D flash means the tranny TCM is unhappy.
the CEL glowing too.
the P0843 means.
Data:
P0843: Open in Transmission Fluid Pressure Switch A (2nd Clutch) Circuit, or Transmission Fluid Pressure Switch A (2nd Clutch) Stuck OFF

first google hit.

After driving a bit the "d" drive indicator starts flashing on my 2009 CSX. Diagnostics indicate P0843 code. What is this?


code p0843 refers to transmission fluid pressure (TFP) sensor A --high input===causes --wiring ---short to positive --TFP sensor---ECM/TCM
replace the sensor .

Error code PO 843


Hi there:
This is a Powertrain fault code, DTC P0843 - Transmission Fluid Pressure Sensor/Switch "A" Circuit High


Generally this could be some gear pressure switch located behind the transmission was broke. Other details in THIS LINK.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

D" blinking is showing on


The PCM senses an abnormality in the powertrain system. Get the code checked, probably a pressure switch though.

The flashing D is a warning signal that there is a transmission problem. Sorry. Below is Honda recommendation for fluid changing.

Also, you coould check this Honda Auto Trans Flush Procedure - Official

Hope helps.

Our 2000 Honda Odyssey shifts hards between 1st and 2nd gear when accelerating fast. The check engine light and TCS lights are on. We just had the transmission replaced 2 years ago. Had it hooked up and it...


I'm not sure why you got that code definition. P1259 in the factory manual reads, "VTEC system malfunction". According to the manual you are supposed to reset the powertrain control module (PCM) then road test--accelerating in first gear to over 4000 rpm and hold that rpm for at least two seconds. If the code does not repeat then do the road test two more times just to be sure. If the code does repeat during the three acceleration tests, then the VTEC pressure switch and solenoid valve should be checked. If the code does not repeat during the three acceleration tests, then the system had an intermittant fault. As for the TCS light being on, I know this may sound simple but is the TCS switch off? If it is, that will cause the light to come on. The TCS light is more applicable to an ABS brake system problem. If the transmission has a fault, you should see a diagnostic code that begins with P07xx or P17xx. The green D4 drive light may also blink. Based on your symptoms of excessive shock in 1-2 upshifts, the book suggests the shift solenoid valve C could be defective, or the 2nd clutch pressure switch or the circuit could be defective, or there could be foreign material in the separator plate orifice, or seven other possible causes. I would suggest clearing the code and replacing the transmission fluid with genuine Honda fluid and then see if the code and the symptoms return.
