Can you extend sensor wires?
From my understand… Since the O2 sensor is voltage based, extending the wires either on the sensor or on the actual harness between the sensor and ECU will increase the resistance of the circuit. So it doesn’t matter if you extend the O2 wires or the engine harness wires, Ohm’s Law prevails.
How can I test my crank sensor for spark?
A spark click and injector pulse should be seen. 3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground, and signal wires. Identify the signal wire using volt meter or diagram. 4) Take the test light and connect to battery ground. With key on, disconnect crank sensor, and repeatedly tap on the signal wire.
How to test the crankshaft position sensor circuit?
Next, Test the sensor circuit by setting your multimeter to “DC volts.” Have your helper turn the ignition key on, but don’t start the engine. Touch the black probe on your meter to ground and the other probe to the power wire. Compare your reading to the specification in your manual.
What do you hear when you disconnect crank sensor?
With key on, disconnect crank sensor, and repeatedly tap on the signal wire. You should hear a spark click and injector noid pulse. These are to test the ECM crank sensor circuit response. On both tests, you should see a spark click and injector pulse.
Can a bad crankshaft sensor cause the engine to stall?
If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall. This is usually a symptom of a wiring problem, however a bad crankshaft position sensor can also produce this symptom.
Is there a safety recall on the S89 crankshaft?
Safety Recall S89 — Crankshaft Camshaft Sensor Wire HarnessPage 8 NOTE: On front wheel drive vehicles only, steps 14 through 16 may be performed from above or below the vehicle per technician preference. 14. Remove and save the one nut and two bolts retaining the heat shield (Figure 10).
What causes a no start condition on a crankshaft?
Improperly manufactured crankshaft or camshaft sensor electrical connector terminal(s) could result in an intermittent electrical connection. An intermittent electrical connection could cause a “no start” condition, the engine to stall while driving, and/or the illumination of the Malfunction Indicator Lamp (MIL).
