DTC Troubleshooting: P0848 (26-4)
Some common causes of a P0848 trouble code include a faulty transmission fluid pressure sensor, bad electronic pressure control solenoid, and blockage within the hydraulic lines of the transmission. Mechanical failure of the transmission can also lead to the storage of this code by the PCM. P0848 Honda – (ASE) Powertrain Transmission Controls Trouble Code Description: Transmission Fluid Pressure Sensor / Switch B Circuit High. Location: Analysis: Possible Causes: Switch B End of Range – Circuit Higher Than Expected Tech description: Honda Vehicle:Honda Accord,Honda Civic,Honda Crosstour,Honda CR-V,Honda CR-Z,Honda Element.
- OBDII/EOBD diagnostics trouble codes definition. If your car supports OBD II or EOBD, then you can already use almost 5000 generic OBDII codes.These codes are from PowerTrain series (P0XXX, P2XXX, P34XX), Body Series (B0XXX), Chassis series (C0XXX), Network series (U0XXX, U2XXX, U3XXX).
- A P0848 diagnostic trouble code is quite serious, because it means either there is a problem with the amount of hydraulic pressure, or there is a problem with the sensors that monitors it. In either case, drivability issues can occur. Symptoms of a P0848 include: Unusually hard or erratic shifting; Transmission will not change gears.
| DTC P0848: | Open in 3rd Clutch Transmission Fluid Pressure Switch Circuit, or 3rd clutch Transmission Fluid Pressure Switch Stuck OFF |
NOTE:
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
| Clear the DTC with the HDS. |
| Start the engine, and warm it up to normal operating temperature (the radiator fan comes on). |
| 7-position transmission: Drive the vehicle in 3rd gear in the D3 position, and verify with the HDS in the A/T data list that the SHIFT COMMAND indicates 3rd. 5-position transmission: Drive the vehicle in 3rd gear in the S position, and verify with the HDS in the A/T data list that the SHIFT COMMAND indicates 3rd. |
| Check the 3rd PRES SWITCH signal with the HDS in the A/T data list. Is the 3rd PRES SWITCH ON? YES - Go to 5. NO - Go to 7. Pc cleaner mac. |
| 7-position transmission: Drive the vehicle in 3rd gear in the D3 position for more than 5 seconds, then shift to the D position, and drive in 4th gear for more than 5 seconds. Slow down and stop the wheels. 5-position transmission: Drive the vehicle in 3rd gear in the S position for more than 5 seconds, then upshift to 4th gear, and drive in 4th gear for more than 5 seconds. Slow down and stop the wheels. |
| Monitor the OBD status for P0848 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate FAILED? YES - Go to 7. NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the 3rd clutch transmission fluid pressure switch and the PCM. If the tester indicates NOT COMPLETED, return to 5 and recheck.n |
| Turn the ignition switch OFF. |
| Disconnect the 3rd clutch transmission fluid pressure switch connector. |
| Turn the ignition switch ON (II). |

| Measure voltage between 3rd clutch transmission fluid pressure switch connector terminal and body ground. Is there about 5 V? YES - Replace the 3rd clutch transmission fluid pressure switch, then go to 15. NO - Go to 11. |
P0848 Honda Accord 2008
| Turn the ignition switch OFF. |
| Jump the SCS line with the HDS. |
| Disconnect PCM connector B (44P). |
| Check for continuity between PCM connector terminal B9 and 3rd clutch transmission fluid pressure switch connector terminal. Mac drawing app. Is there continuity? YES - Check for loose or poor connections at PCM connector terminal B9. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n NO - Repair open in the wire between PCM connector terminal B9 and the 3rd clutch transmission fluid pressure switch, then go to 15. |
| Clear the DTC with the HDS. |
| Start the engine, and warm it up to normal operating temperature (the radiator fan comes on). |
| 7-position transmission: Drive the vehicle in 3rd gear in the D3 position for more than 5 seconds, then shift to the D position, and drive in 4th gear for more than 5 seconds. Slow down and stop the wheels. 5-position transmission: Drive the vehicle in 3rd gear in the S position for more than 5 seconds, then upshift to 4th gear, and drive in 4th gear for more than 5 seconds. Slow down and stop the wheels. |
| Monitor the OBD status for P0848 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate PASSED? YES - Troubleshooting is complete.n NO - Return to 7 and recheck. |
