boyfriend has replaced 2 of the tcs sensors and it

Are there any lights lit up on the instrument cluster, like a check engine light? If so, did you scan for the codes? What we're they? ex. P0171

When my car cuts off it has the TCS, and check engine light on. It's crazy because it's still power it just cuts off.

i just went through this same thing. it's the camshaft sensors, replace both of them. courtesy nissan is where i got them. they are oem, don't buy aftermarket ones. it will cost 72 dollars and your boyfriend should be able to replace them. go to autozone or somewhere they can run a diagnostic check, if the codes are P0340 or P0345 this will fix your car


i had same/similar problems and it was a throttle position sensor, problem went away after replacement, also possible that the mass air flow sensor is bad, have the codes read to see where it leads and replace those sensors with OEM parts is a good start.
