A
cam sensor is a device that helps a car's engine control system determine the position and speed of the camshaft. It plays a crucial role in synchronizing the opening and closing of the engine's intake and exhaust valves, making sure the engine runs smoothly and efficiently.

Other hardware improvements will supposedly include a jump from 2 to 3 GB RAM, as well as rear and
front cam sensor bumps to 20 and 8 megapixels respectively.
I
changed cam sensor and crank sensor but did not use OEM parts and was told by a mechanic this could be the problem.
We have had the fuel pump replaced as well as the crank and
cam sensors.
Could be stretched timing chains or a problem with the vvt gear, stretched chains will give an incorrect reading between
the cam sensor and the crank sensor (essentially engine is out of time) and will usually fail to start once stretched to far, if the correlation between cps and crank sensor if different for I think 5 seconds car will not start
Yep, check engine light as well as stalling, usually at slow speeds, or when shifting from drive to reverse, or vice versa if
the cam sensor is bad.
While the crankshaft position and
cam sensors are vital for ignition timing, when they fail, it usually prevents starting.
Second, if you replaced
the cam sensor...
If you find you do not have spark, I would check on the ignition coil, crank sensor, and
cam sensor.
It is not uncommon for ignition coils and
cam sensor to fail on these vehicles, especially as they hit higher mileage numbers.
The cam sensor code (actually P0344), is known problem, and there is a Technical Service Bulletin (232460) that addresses this fault and repair.
These codes both indicate a problem with
the cam sensor for bank 1, or A, on the passenger's side of the engine.
In your case, however, you have a no start condition, so assuming the timing chain has not slipped (you should still check that carefully, especially if gear teeth have broken), I would suspect one of these possibilities: tone ring on crankshaft slipped / broken; tone ring on camshaft slipped / broken; bad crank sensor; bad
cam sensor; and / or damaged wiring to crank / cam sensor.
Many water pump kits included new chains, guides and sprockets but
the cam sensor notch was in the wrong place and the engine would not start after repairs.
Here's a list of repairs done through out my 10 yr ownership: all PWR windows, climate control, blower motor resistor, instrument panel, steering system, A / C compressor, cracked ac vents, wheel bearings, coil packs, crank sensor,
cam sensor, oil seals, engine, transmission (2x), lower control arms, valve cover seals, EGR sensor, coolant reservoir, starter (x2)!
Here are the bits and pieces replaced: Transmission, Tie rods, steering system, A / C compressor, All pwr windows,
Cam sensor, Alternator, Crank sensor, control arms, Stereo and speakers, pwr window switches (x3), coolant reservoir, idler pulleys (x2), climate control, valve cover seals, blower motor and blower motor resistor (rusted), air vent covers (cheap plastic), door panels, starter.This vehicle has cost me more in repairs than any vehicle I owned!
The LAP is a 2.2 L — 2,198 cc (134.1 cu in)-- version of the Ecotec, based on the Gen II block with cylinder head improvements, new camshaft design, E37 engine control module, 58X crankshaft reluctor ring, dual variable valve timing, digital crank and
cam sensors, individual coil - on - plug ignition, vented starter solenoid, new MAP sensor, new intake manifold seals, new oil filter element, a 32 - bit computer, and improved emissions performance.
It was also switched to an E37 engine controller with new crank and
cam sensors (replacing timing sensor previously found in ignition cassette).
