Hello All,
Just joined this community, have owned a CR-V for the last 3 and a half years, with no real trouble from the car. but have ran in to a problem that has got me stumped. so apologies in advanced for the long post. As have been searching through this forum to find a solution and tried different fixes all with no avail.
Was on holiday in south Yorkshire and after driving back up to Scotland (300 miles drive), the next day i went out to start the car, and got the PGM-FI error on the display, hooked up ODB2 scanner and obtained the following code P0181, (Fuel Temperature/Engine Coolant Temperature (ECT) Sensor/Intake Air Temperature (IAT) Sensor voltage correlation.
On checking the car i found that the hose between the airbox and turbo had a 2 inch split in it, so suspected that was the possible issue, so replacement hose ordered and fitted. Codes cleared, next morning same error.
Suspected that possibly debris had got in to the system and blocked\fouled the MAF sensor, removed sensor and cleaned, error cleared, next morning same issue.
Ordered a replacement MAF sensor and fitted, cleared code, next morning same issue, error is back.
After more trolling through the forums and the web, found a link to the Honda Maris website and bought an hours access, checked the site and found that i should have done a MAF sensor learning clear and a DPF regen after the MAF sensor was fitted, so done this and cleared codes next morning same error. Maris website diagnostics said replace Fuel Temperature sensor, So ordered replacment from COX Autoparts, and fitted, code cleared, next morning same error.
More searching on the web and the forums suggested possible glow plug issues, ODB scanner not picking up any error codes related to glow plug issues. but tested plugs in-situ. plug number 2 shown to have intermittent readings, so new set of Bosch plugs ordered and fitted, codes cleared, this morning same error is back.
Engine coolant temperature sensor was replaced last year due to failure.
So now completly stumped as to what could be causing the issues. Car runs fine with no loss of power and fuel economy is in the ball park of 50 - 55 MPG.
some data from the ODB2 scanner with the car idiling at 800rpm
Fuel Rail pressure 24.36 Mpa
Fuel RaIl pressure Target 28.04 Mpa
Fuel Rail Control Valve Target Pressure 23.81 Mpa
IAT Sensor 1 21 Deg c
IAT Sensor 2 34 Deg c
MAP 99Kpa
Map Target 99Kpa
Car has always been run with BP diesel where possible and the occasional can of Original Syprin diesel addative through the tank every 12 months. Car has 87k on the clock and has been serviced at regular intervals. Even local mechanic is stumped as to what could be causing it.
any help\suggestions welcome
Colin.
