Operation



Specific to:

Suzuki Forenza 2007-2008

Suzuki Reno 2007-2008

The Camshaft Position (CMP) sensor sends a CMP sensor signal to the Engine Control Module (ECM). The ECM uses this signal as a -sync pulse- to trigger the injectors in the proper sequence. The ECM uses the CMP sensor signal to indicate the position of the #1 piston during its power stroke. This allows the ECM to calculate true sequential fuel injection mode of operation. If the ECM detects an incorrect CMP sensor signal while the engine is running, DTC P0341 will set. If the CMP sensor signal is lost while the engine is running, the fuel injection system will shift to a calculated sequential fuel injection mode based on the last fuel injection pulse, and the engine will continue to run. As long as the fault is present, the engine can be restarted. It will run in the calculated sequential mode with a 1-in-6 chance of the injector sequence being correct.

Testing



Specific to:

Suzuki Forenza 2007-2008

Suzuki Reno 2007-2008


NOTE
An intermittent problem may be caused by a poor connection, rubbed-through wire insulation or a wire that is broken inside the insulation.


NOTE
Any circuitry that is suspected as causing the complaint should be thoroughly checked for the following conditions:



Backed-out terminals
 
Improper mating
 
Broken locks
 
Improperly formed
 
Damaged terminals
 
Poor terminal-to-wire connection
 
Physical damage to the wiring harness
 

  1. To test with a scan tool.
  2.  
  3. Turn the ignition OFF.
  4.  
  5. Install a scan tool to the Data Link Connector (DLC).
  6.  
  7. Idle the engine.
  8.  
  9. The Camshaft Position (CMP) Active Counter should be incrementally counting as the vehicle runs.
