Hi everyone,
I need some advice with my Mazda 3 2.2 diesel, 2015.
The car has done around 150,000 km and has always been serviced by Mazda.
Hi everyone,
I need some advice with my Mazda 3 2.2 diesel, 2015.
The car has done around 150,000 km and has always been serviced by Mazda.
The problem started after I had battery issues. The car would not start, so I tried to jump-start it. The first few jump-start attempts did not work. After trying for a while, I finally managed to start the car.
Since then, I started getting a Master Warning Light on the dash.
To be clear, the only warning I can see on the dash is the yellow triangle / Master Warning Light. I do not have any other warning light showing on the display. I do not see a red oil pressure light staying on, and there is nothing else obvious on the dashboard display.
When I checked/cleared the warning, the message or fault comes back as Low Oil Pressure.
I already cleared the code, but it keeps coming back.
The strange thing is that the issue only started after the battery/jump-start problem, so I am trying to understand if this could be related to an electrical or voltage issue rather than a real oil pressure problem.
The old battery was:
EFB Start & Stop 60640
12V 60Ah 640A EN
The replacement battery fitted is:
VARTA N70ZZL EFB 12V 75Ah 820A
The car starts and the engine sounds good. There is no obvious knocking, rattling, or abnormal engine noise, but the warning returns after clearing.
I want to know if the jump-start could have damaged or confused the oil pressure sensor circuit, or if this is likely to be a real oil pressure issue.
I understand that if the warning says Low Oil Pressure, it should be treated seriously. I am not trying to ignore it. I just want to know the correct diagnostic order before replacing parts.
Has anyone had a similar issue on a Mazda 3 2.2 diesel around 150,000 km, especially after a battery change or jump-start?
Could a bad jump-start cause a false Low Oil Pressure warning through the oil pressure sensor, wiring, ground, fuse, or ECU voltage?
Or should I assume it is a real oil pressure problem until a mechanical gauge test proves otherwise?
Any advice from Mazda diesel owners or mechanics would be appreciated.
