Trouble code P0401 means: Exhaust Gas Recirculation Flow Insufficient Detected
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
EGR FLOW INSUFFICIENT DETECTED.
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
The 1997 Honda Prelude has OBD II, there is no conversion. You will need a scan tool or code reader that is capable of reading OBD 2 codes. From 1996 up all vehicles with few exceptions are mandated by the Government to have OBD II systems. This was put into place to standardize codes and make diagnosing problems easier.
Trouble code P0401 means: Exhaust gas recirculation - insufficient flow detected
it is on passanger side floorboard on side of console
The OBD connector on a 1992 Honda Prelude is located under the dashboard, near the driver's side, typically just above the area where the brake pedal is located. You may need to remove a cover or panel to access it. It's usually a 16-pin connector, which is standard for OBD-I systems.
Yes, you can use an OBD (On-Board Diagnostics) reader on a 1995 Honda Prelude Si, but it's important to note that this vehicle is equipped with OBD-I, not the more common OBD-II system found in cars produced after 1996. To read the diagnostic codes, you may need a specific OBD-I scanner or an adapter that can interface with the OBD-I system. Remember that the available data from OBD-I is more limited compared to OBD-II.
replace the EGR valve and reset the OBD II Exhaust Gas Recirculation valve
The 1987 Honda Prelude 2.0 Si is equipped with OBD-I (On-Board Diagnostics version 1). This early diagnostic system primarily monitors engine performance and emissions control functions but lacks the extensive capabilities of later OBD-II systems, which were introduced in the mid-1990s. OBD-I systems typically provide limited diagnostic trouble codes and require specific equipment for reading the codes.
There is no obd port. You can peel back the carpet under the passenger foot area and reveal the ecu. From there you can read the led flashes to find out what codes are being displayed.
if its a us Honda then its under the dash on left if its a UK Honda then its not obd compliant until 2001 actually i believe only 1996 and up year civics have an OBD port for plugging in the scanner..
