Cutting out at 90 degrees

147 2.0 litre twin spark 2002.

I've read a lot of posts there is a lot of talk about the crankshaft sensor but nothing much about coolant temp sensor.

Fault = car will cut out at 90 degrees then restart when cold.

Plugged into to diagnostic:
P0335 Crankshaft sensor - defective
P0336 Crankshaft sensor - outside specified range.
P0115 Coolant Temp Sensor - defective
P0130 O2 sensor (bank1 sensor1) - defective
P1135 O2 sensor heater resistance (bank1 sensor1) - incorrect value

Do you think the 1 sensor will be throwing the other sensors out? or all the sensors are faulty?

cheers for any advice.

I would replace the crankshaft sensor, reset the errors and see if that also solves the other problems .....

Replace crankshaft sensor and coolant temp sensor (check wiring to temp sensor first so they are ok), clear the faults and reset adaptive values, drive the car and see if O2 sensor faults do return they may be caused by a
faulty coolant temp sensor.
