My car just died and wouldn't restart (OR TURN OVER). After doing a scan I found it had a p0335 code - I need to know who to call to fix it which depends on the amount of work involved. Would you please tell me where it's located in the motor and how much work is required to get there and out...

hi the sensor is in with the timing belt. You will have to remove the timing belt cover and belt to put a new one in. You will also see a small gold metal rotor that spins on this sensor also replace that or it will trash the new sensor.

Knock Sensor Description addthis_pub = 'car-suff'; A quality Knock Sensor is more important than ever thanks to today’s increasing gas prices. Your Engine Knock Sensor enables your vehicle to obtain the optimum combination of timing and fuel/air mixture to generate power and efficiency and that means less wasted gas. Our guaranteed low prices make us your one-stop Knock Sensor Location. Regardless of the brand, make or model car, truck, van or SUV you drive, we make it easy to locate the application specific Knock Sensor that’s perfect for your vehicle. Our state of the art parts locating system puts you just a few mouse clicks away from the Knock Sensor you need and at a price you cannot beat anywhere. Click. Click. Click. And you are there. In addition to robbing you of fuel economy and performance a faulty Knock Sensor can cause expensive damage to your engine. Remember, the Knock Sensor keeps fuel from detonating in the cylinder … exploding rather than quickly burning as it should. If not replaced a faulty Knock Sensor can quite literally cause hundreds if not thousands of dollars in damage. There is really no need to look any further to find the Knock Sensor that’s application specific for your car, truck, van or SUV – high performance or family vehicle. We’ve got guaranteed low prices and shipping that other suppliers envy. Give us a try, we think you’ll be happy … in fact we guarantee it.

crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
The crank sensor can be used in combination with a similar camshaft position sensor to monitor the relationship between the pistons and valves in the engine, which is particularly important in engines with variable valve timing. It is also commonly the primary source for the measurement of engine speed in revolutions per minute.
Crank sensors in engines are usually comprised of magnets and an inductive coil. They are principally based on the Hall effect. Common mounting locations include the main crank pulley, the flywheel, or occasionally on the crankshaft itself.
Some engines, such as GM's Premium V family utilise crank position sensors which read a reluctor ring integral to the Harmonic Balancer. This is a much more accurate method of determining the position of the crankshaft, and allows the computer to determine within a few degrees the exact position of the crankshaft (and thereby all connected components) at any given time.

Hi
On the 2.7 engine it is located beside the starter. You will have to remove the starters heat shield to gain excess to the crank sensor.

P0157 - O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.
NOTE: If the crank sensor is used only for misfire detection and NOT spark timing (this varies with the vehicle), the vehicle should start and run with MIL (Malfunction indicator lamp) illumination. Also, some vehicles require several key cycles to illuminate the MIL. If this is the case, there may be no MIL illumination until the problem often enough over time. If the crank sensor is used for BOTH misfire detection and spark timing, the vehicle may or may not start.
Symptoms may include:
* Vehicle may not start (see above)
* Vehicle may run rough or misfire
* MIL illumination
Causes: A P0335 "check engine light" code could be caused by:
* Damaged CKP sensor connector
* Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
* Sensor output open
* Sensor output shorted to ground
* Sensor output shorted to voltage
* Failed crank sensor
* Broken timing belt
* Failed PCM
Possible Solutions:
1. Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
2. If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
3. If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
4. If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.
This code is basically identical to P0385. This code P0335 refers to Crankshaft Posistion Sensor "A", whereas P0385 refers to Crankshaft Position Sensor "B". Other crank sensor codes include P0016, P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.
P1372 - Segment Time Incorrect
This engine is very sensitive to overheating and will easily warp the
cylinder head. On the other hand, all the performance symptoms as well
as the misfire code can be caused by a faulty crank sensor.
This leaves you at a crossroads as to how to diagnose. You could
replace the crank sensor and see what happens. Or you could do a
compression test to get an idea of the general health of the engine.
As for the lack of heat, you may have an air pocket in the cooling
system or it may not be completely repaired. If, for example, the
thermostat were stuck shut causing the pressure to build and crack your
radiator, you'd still have the problem that you have no coolant flow,
resulting in no heat.
Unfortunately, considering the overheating, my inclination is that
you're more likely to need a cylinder head than any of the minor repairs
I've suggested. But the only way to find out is to check the cooling
system, compression, and crank sensor.
Hope helps.
