Bad cam sensor opel astra

Opel Zafira 1.6B gen2 Petrol not CNG fuel ,right? A.K.A, FAMILY 1 ENGINE.
SINGLE OR TWIN CAM?

a total lack of power , full power(engine) weak. (stick shifted)
400RPM means the PCM can not control idle. AT ALL.
check fuses first.!
scan it next using a real scan tool not some $20 code reader.
there are in fact many causes for this, and newer the IAT intake air temp sensor) EGR stuck open sure. but not now egr is new(main valve)

1. a bad engine, even cam belt slipped. never allow this.
2. bad spark, 1 or more coils , spark plug bad.
3. bad fueling too rich or too lean or bad fuel

so did you drive the car over 100km and not replace the cam belt
if yes oops. that can wreck the engine or bend valves.


sold here and with many 1.6L engine variants
Europe (except for United Kingdom), Japan, China, Hong Kong, Singapore, Taiwan & South Africa

The service light comes on when a service is due and turned off by the service mechanic after the service , could that be the fault?.

Could be a fuel problem/Blockage.
Good Luck

Idle air control valve, leak in intake hose after MAF, bad tune up parts, clogged exhaust, weak coil, etc.

Guessing just wastes money . have the fault codes read first and find exactly which sensor/s are causing you a problem
not all faults energize the engine light and remember the engine light also refers to problems in the transmission

motormounts may b worn or car needs tuneup-change plug wires--coil--distributer cap........causing misfiring---cud hav an injector issue tu doing the same thing---------

check that you have the timing right for no 1 piston as you may be 180 degrees out.

locate the crank sensor there should be two screws and a electric plug pretty simple if u can locate the sensor

There are sensors that detect if the engine is running after it starts. Oil pressure sensor is a major one. I don't know exactly since I don't have an electrical diagram to see all the possible sensors.

check your throttle position sensor and your maf sensor.
