Engine Mechanical problem
2000 Plymouth Neon 4 cyl Front Wheel Drive Automatic 180000 miles

It says Camshaft Pos. Sensor A-Bank 1 Circuit Malfunction? I can not get car to start now and it seems to be leaking engine coolant(antifreeze)near bottom of Water pump. Does this code mean I broke a timing belt or is the Camshaft sensor broke and allowing coolant to leak out of the block? Thanks for your help! Mike.

Do you
have the same problem?

Hello .. thanks for the donation .. much appreciated

You will need to check the timing belt and check why the pump is leaking ? the leak should have no affect on the CMP sensor.... do these simple test's and let me know your result's .. also the reason's for the leak ..the CMP will not produce a signal to the PCM if the timing belt has broken so you need to check this !

Cam signal is monitored during engine cranking after 32 Crankshaft Position Sensor (CKP) signals have been detected. DTC may be stored in Powertrain Control Module (PCM) when no signal is received from Camshaft Position (CMP) sensor when CKP sensor signal exists. Possible causes are: defective camshaft position sensor or target magnet, defective PCM, or defective connectors or wiring.

Turn ignition on. Using scan tool in INPUTS/OUTPUTS, read CURRENT CMP STATE while cranking engine. If scan tool displays PRESENT while cranking engine, go to step 16 .
Turn ignition off. Disconnect connector at CMP sensor. CMP sensor is located on rear of cylinder head, just below valve cover. See Fig. 31 . Turn ignition on. Using voltmeter, check voltage at CMP sensor connector terminal No. 1 (Orange wire). If voltage is less than 7.5 volts, go to next step. If voltage is 7.5-8.5 volts, go to step 9 . If voltage is more than 8.5 volts, repair short to voltage on Orange wire. Perform TEST VER-5A .
