Explanation:
http://www.dsmtuners.com/threads/1g-code-reader-cel-code-reader.319844/
I found this thread and I actually performed the buzzer method, instead of the led. Spot on advice.
I counted 13,15,21 and 25 as codes on my car and from that thread I have this:
Query:
1.) Motor position sensor: Is this the throttle position sensor, located on the intake manifold?
2.) I checked my Haynes manual: No idea where the Baro and Intake air temp sensor is located. ( Is/are these integrated with the MAF? ) I half expect the IAC to be on the intake.
Methodology check:
3.) If the result of question 2 is MAF, then what is the probability that a vacuum leak could cause incorrect readings on multiple instruments? Do these instruments typically falter when in the presence of a vacuum leak, or is the ECU capable of deriving a status of a sensor, or a simple logical check against an expected value? In other words, does the ECU recognize the status of a sensor, and an out of specification reading on a sensor? Can the ECU signal a fault condition, without assuming the sensor is at fault?
Thanks for your time.
