Example of the typical electrical signal of a sensor (1) This area represents the normal operating range of the engine parameter. (2) In these areas, the engine is operating in an unsafe operating range of the monitored parameter. A diagnostic code that indicates an engine event will be generated for the monitored parameter. The sensor circuit does not have an electronic problem. Refer to Systems Operation, "Engine Monitoring System" for additional information that is related to engine events. (3) In these areas, the signal from the sensor is outside of the operating range of the sensor. The sensor circuit has an electronic problem. A diagnostic trouble code that indicates that a problem with the circuit has been detected will be generated.When you troubleshoot a diagnostic trouble code, be sure to evaluate the problem from the viewpoint of an interpretation of the electrical signal. Refer to the above illustration for an evaluation of the sensor signal.Cross-Reference Information for Diagnostic Codes
Table 1 is a list of the diagnostic codes for this engine. The diagnostic codes are cross-referenced with the appropriate procedure that can be used to troubleshoot the code.
