Hello all,
I am really hoping someone is able to help. I have 4x fault codes showing on my 2003 K12 Micra; 1x has been there for a week or so, the other 3x appeared today.
The codes are:
P0037 - Bank 1 Sensor 2 Heater Circuit Low
P0107 - MAP/BARO Circuit Low Input
P0113 - IAT Sensor 1 Circuit High Input
P0444 - EVAP Emission Control System Purge Valve C Open
I presume a single filter/sensor is triggering the bottom 3x fault codes as strange for all these issues to come about at the same time?
I have tested the vacuum solenoid valve by connecting 12v to it and i can hear it clicking. I have also blown air through the holes and the valve has worked as expected. The solenoid is not leaking air. I measured 10v coming from the connector that plugs into the solenoid, with the car battery on 12.5v.
I have cleaned the throttle body, replaced the camshaft, crankshaft, coolant temperature sensors. The oil and liquid levels are good.
I did notice the intake seals at the back of the engine block look a little worn and could probably do with renewal - i do not know if this is likely to be a cause of the error codes i now have?
I have had a few issues with the car in the run up to these fault codes. These issues are:
- Struggling to start in the cold weather - needing multiple attempts and some throttle to get it started; although when i remove the breather hose from the vacuum solenoid to the air intake on top of the engine, this seems to help it turn over, then reapplying the hose.
- the past day or so the engine has completely cut out whilst driving - no juddering etc, just a calm shutdown. If i turn the ignition, it comes back to life.
- occasional rough idle - sometimes at a standstill the engine almost stalls itself and i need to give it a bit of gas to keep it turning over. There are no issues with driving.
- my coolant temperature light stays on blue for long periods of time and goes off and comes back on at various intervals during driving, sometimes it does not go off. I have a replacement thermostat, but have not yet installed this. I am hoping this cures this issue.
Please, is anyone able to shed some light as to what might be going on here? I am not 100% on what the fault codes are trying to tell me, but have tried to figure them out as best i can.
