What does a camshaft sensor do?
The camshaft position sensor gathers information about the vehicle's camshaft speed and sends it to the vehicle's engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires.Where is the camshaft position sensor located on a 2002 GMC Envoy?
FAQs for GMC Envoy Camshaft Position Sensor Products located right on TOP of engine (passenger side) right by the coolant hose. There is a separate one located on the BOTTOM (drivers side) of the engine.How do you start a car with a bad crank sensor?
How to start a car with a bad crankshaft sensor: turn on the ignition if and only if you have the check engine light on and minimal symptoms beyond that.

What a P1345 code means. The powertrain control module (PCM) compares the crankshaft position (CKP) sensor data to the camshaft position (CMP) sensor information to ensure the two shafts are where the PCM expects them to be. This is especially important on vehicles with variable valve timing (VVT).What is the code p1345?
Error Code P1345 is defined as Crankshaft Position-Camshaft Position Correlation. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Audi, GM (Chevrolet/GMC), Isuzu, Lexus, Mazda, Toyota, and Volkswagen.Can you test a crankshaft position sensor?
A multimeter can measure voltage, current, and resistance. You can remove the sensor, and then test the resistance. Attach one end of the multimeter to each wiring lead of the sensor. Another way to test the crankshaft sensor with a multimeter is by checking the output voltage with the engine cranking.Can a car run without a crankshaft position sensor?
The crankshaft position sensor is the most important of all engine management sensors, and the engine will absolutely not run without it. Many systems are smart enough to try guessing should this sensor fail and allow the engine to run without it. In your case, a magnetic crankshaft positioning sensor is used.What is the difference between a camshaft sensor and a crankshaft sensor?
On many engines with distributorless ignition systems and sequential fuel injection, a camshaft position sensor is used to keep the engine's control module informed about the position of the camshaft relative to the crankshaft. Operation and diagnosis is essentially the same as that for a crankshaft position sensor.How much does it cost to replace a crankshaft sensor?
The average cost for a crankshaft position sensor replacement is between $190 and $251. Labor costs are estimated between $102 and $130 while parts are priced between $88 and $121. Estimate does not include taxes and fees.Can I clean a crankshaft position sensor?
Clean the crank position sensor very good. Remove it and clean the actual sensor and also clean the area of the engine that the crank position sensor mounts to. The reason is that some crank position sensors are very sensitive, in particular the grounding.Can you clean a camshaft sensor?
Cleaning the Camshaft Position Sensor Sometimes, cleaning the camshaft sensor can do the trick and bring back your ride's optimum performance. After that, take the sensor out and place it on a clean rag. Step 4: Next, spray some aerosol solvent on the camshaft position sensor and then use a new rag to wipe it dry.Does crankshaft sensor affect fuel pump?
Lowered Fuel Efficiency: Since a bad sensor affects fuel injection, the engine will not receive the proper amount of fuel at the right time, resulting in lower fuel efficiency. Engine Stall: Crankshaft sensor problems can also make your engine stall at low speeds and the car will have difficulty while starting.
