C240. Motor cranks then stalls
Hi everyone. First of all thanks for taking your time to read my current issue.
I have a 2001 C240 elegance. With recent tune up done (oil, spars, etc. Issue was still intermittent before tune up)
1st issue. Motor would start on the couple of tries, usually on the 3rd attempt the engine would crank with no problems.
I had initially thought it was the crankshaft sensor issue and purchased the sensor.
Before doing any changes or installing the sensor. I was able to get my hands on a OBD2 reader and scan the engine. By now the engine continues to start intermittently and when it does, it goes off and stalls.
The OBD2 result is:
P0110 Intake air temp sensor (I had the covers off, reason why this may have come up)
P0100 Mass or Volume air flow sensor
So nothing came on, regarding the Crank shaft position sensor (Which I didn't change and count tell how to, the space is so limited and I was not able to see nor tell. Most videos of similar model appear to have a more space to reach and change it)
So I took out and cleaned the MAF, I sprayed it with some circuit cleaner (Since I didn't think the MAF would cause issues like this, and make the motor stall)
I put everything back together now and the MAF cleaned, Cleared the codes on the OBD2 and checked for another scan.
This brings me to my second issue.
Now Im scanning for new error codes, and nothing comes on, there are no errors on the OBD2 (tried different apps) all with no results.
Car continues to crank the stall. I was able to capture this message though on one of the apps: ¨Open Loop due to insufficient temperatures¨aparently on the fuel system.
Does any one have any input that can guide or help me get this sorted out?
Again, I really appraise everyone time and efforts.
