The onboard computer senses the position of the crankshaft by monitoring the output from the crankshaft position sensor. With that information, and the input from other sensors, the computer can determine appropriate injector duration, ignition timing, EGR valve operation and transmission shift points.
I cant remember if a 1994 had a distributer or not. If it has a distributer, there is no crankshaft position sensor. That information is a calculated value using the input from the distributer stator(pickup coil). If there is no distributer, then there will be a crank sensor on the front of the engine down by the crank pulley.
Trouble code P0347 means: Crankshaft position sensor "A" low input (Bank 2)
Trouble code P0327 means: Knock sensor #1 circuit low input (Bank 1 or single sensor) Trouble code P0332 means: Knock sensor #2 circuit low input (Bank 2) Trouble code P0336 means: Crankshaft position sensor "A" range or performance problem
You cant. Timing is controlled my crankshaft position sensor and other sensors that monitor air flow and engine load. The PCM is ultimatley responsible for timing control by reading sensor input values.
Trouble code P0300 means: Random/multiple cylinder misfire detected Trouble code P0337 means: Crankshaft position sensor "A" low input
P0320 Ignition/Distributor Engine Speed Input Circuit Malfunction. Crankshaft position sensor, wiring, or pcm problem. Check the sensor and tone wheel on the crankshaft, and wiring to the sensor. There is a 2 pin connector down near the CPS, it gets corroded down there, remove the CPS and unplug, clean and pack with a dielectric grease ( seals water out).
The engine speed sensor provides the ECM with a crankshaft position signal. The ECM uses the signal to determine a crankshaft reference point (Top Dead Center) and calculate engine speed (RPM.) The signal is also used by the On-Board Diagnostic system for misfire detection. The ignition system will not operate if the ECM does not receive an engine speed sensor input.
How do i fix the TPS pedal position sensor in a grand prix pontiac 2004.
TPS sensor, low input (throttle position)
Here's the technical description of the p0340-344 diagnostic trouble codes: P0340 Camshaft Position Sensor Circuit Malfunction P0341 Camshaft Position Sensor Circuit Performance P0342 Camshaft Position Sensor Circuit Low Input P0343 Camshaft Position Sensor Circuit High Input P0344 Camshaft Position Sensor Circuit Intermittent Obviously, the camshaft position sensor (CPS) is the probable source of the problem. See "Related Questions" below for more about the CPS
P0320 Ignition/Distributor Engine Speed Input Circuit Malfunction NO CRANK REFERENCE SIGNAL AT PCM No signal from the Crankshaft Position Sensor is present during engine crankingBad crank sensor is most likely cause.
