Hey guys and girls,
Been reading around the forums for a while trying to fix my problem but after chasing a lot of leads ive come to a dead end.
Since the last basic service i did (oil, oil filter, air filter) I noticed my girlfriends car using excessive amounts of fuel. Not sure if it was performing this badly before but watched it closely after a service as I dont really drive it. Being a '97 model im not expecting the moon but currently only getting around 350-400km on mostly highway driving. Around town it can drop down to around 300 or less.
The first thing I did was check for codes bridging connections 4 and 15. Nothing. Received 4444.
Not knowing the history of the car I decided to go over most things to cover my bases.
replaced
- Fuel Filter
- ECT sensor
- o2 Sensor
and cleaned
- AIT sensor
- MAF sensor
- TPS sensor
- Throttle body
the last things i have done from the list are replace the o2 and ect sensor, reset the ecu and checked for codes again and now receive 4151, air/fuel ratio. Would this possibly be because the old sensors were not reading correctly and missing another more identifiable problem?
Any more light to be shed with this code or will i need to have a proper scanner plugged in for more information?
Or have I missed something completely and am stupid. Either way Id love some input just to have something to look at.
