Hi! Need advice , when vehicle is cold , its starts normally , but when its getting to the normal operation tempature if i turn the cehicle off its not gonna start again till its cool down.
No errors. Thank you in advance!!!!

 

Worth scanning for errors. Typically Maseratis do this when the CPS is failing. This may not be helpful information

Hello ​​​​​​@Felix Smolensky,
As CatmanV2 stated, failing CPS, as a failing CPS = crank position sensor will give you exactly what you describe, with no fault code / check engine light, or if you scan engine ECU'S 1 and 2 you may find an Intermittent CPS fault, but you must scan with the proper tool, like Ross-Tech VCDS.

The CPS with part number 070 907 601A is located on the transmission at the 6 O'clock position.

The last picture above, is the CPS with it's connector broken off...

 

Thx for replies guys! Gonna check tonight.

 

​​​Hi @Felix Smolensky ,
Just to be specific, I as many call it a crank position sensor/CPS, but it's technical name I guess is that it is a engine speed sensor / ESS aka G28.

I just didn't want you looking for the wrong item.
