Does anyone know where this sensor is (pictures discription)how can i check mine. I am getting the code of 0101. Any help is greatly welcome.

 

First remove the engine from the car.......Sorry just a little humor.

The camshaft position sensor is located on the front timing chain cover. Facing the passenger side of the engine it's the sensor located a couple inches to the right of the side engine mount and a couple inches directly above the adjuster for the pulley to the AC and alternator belt. There is nothing else in that area.

Per the Haynes manual use an ohmmeter and measure the resistance across the two camshaft sensor terminals. Resistance should be 1,440 to 1,760 ohms at 68 degrees F for a hitachi made sensor. For a mitsubishi made sensor the ohmmeter should read 2,090 to 2,550. The make of the sensor should be imprinted on it. As to the temperature requirement room/air temperature is fine. Don't take a reading after pulling the sensor off a hot motor.

If the sensor values are correct check the wiring for a short, bad ground, or damaged harness.

 

Hahahaha funny thank you for your help.

 

There's some confusion over the DTC 0101 code, as the Haynes Manual suggests two possibilities based on the Diagnostic Scan Tool codes that a dealer uses (i.e. Pxxxx):

DTC 0101 = P0155 = Upstream oxygen sensor heater or circuit fault (left bank)

In addition,

DTC 0101 = P0340 = Camshaft Position Sensor (Phase) or circuit fault

Regarding the Camshaft Sensor, a search yielded more confusion than answers, so here goes my best Daniel B. impersonation:

DTC 0101 (P0340)

Diagnostic Trouble Code 0101 points to a problem with the Camshaft Position Sensor, should the scan code correlate to P0340.

The camshaft position sensor is located on the timing chain cover at the front of the engine. The sensor uses a permanent magnet, core and coil to detect a gap in the camshaft sprocket. The changing gap causes the magnetic field near the sensor to change, this in turn varies the voltage signal to the PCM. The camshaft position sensor provides information on cylinder TDC position to the PCM.

To remove, disconnect the electrical connector from the sensor. Using an ohmmeter, measure the resistance across the two camshaft sensor terminals. Resistance values should be:

For Hitach branded CPS:

1,440 to 1,760 ohms @ 68 degrees F

For Mitsubishi branded CPS:

2,090 to 2,550 ohms @ 68 degrees F

If the resistance values are incorrect, replace the sensor. Should the resistance values be correct, refer to the wiring diagrams and check the wiring harness for an open circuit to the PCM or a damaged harness. Check for continuity to ground on the black wire of the harness connector. If the sensor and the wiring harness are both good, have the PCM diagnosed by a dealer service department or other qualified repair shop.

Also, it should be noted that if this code arises along with DTC 0802 indicating a Crankshaft Position Sensor (POS) or circuit fault, another possibility is the vehicle’s battery is at fault.


I can't believe a DTC code can mean two different things.
