Довыделывался. Загорелся Сер.Энж.Соон.Ехал на газу по трассе на круизе.
Скрепка говорит 44 и 45. Может не так понимаю, но это вроде взаимоисключающие ошибки?
44 Lean exhaust
45 Rich exhaust
CODE 44
Trouble Code 44 indicates that the O2 sensor is showing a persistently high exhaust oxygen content (lean), despite the efforts of the ECM to increase injector on-time (thus increasing fuel delivered). Integrator and BLM numbers may indicate > 128 by a substantial margin.
The conditions for setting this code are:
•no Code 33 or Code 34 (MAF Error) present, and
•the O2 sensor voltage remains below 250 mVolts, and
•the ECM is in Closed Loop control, and
•the above conditions exist for more than 50 seconds.
Typical causes for this code include:
1) O2 sensor defective or lead shorted
2) Lean injectors (dirty or blocked)
3) Water in fuel
4) Exhaust leaks upstream of O2 sensor
5) Fuel pressure or volume too low
6) MAF sensor reading lower airflow than is actually present
7) Vacuum leaks
Incorrect or poorly calibrated PROM

CODE 45
Trouble Code 45 indicates that the O2 sensor is showing a persistently low exhaust oxygen content (rich), despite the efforts of the ECM to decrease injector on-time (thus decreasing fuel delivered). Integrator and BLM numbers may indicate < 128 by a substantial margin.
The conditions for setting this code are:
•no Code 34 or Code 35 (MAF error) present, and
•the O2 sensor voltage remains above 752 mV, and
•the ECM is in Closed Loop control, and
•throttle position is < 2 percent or > 20 percent, and
•the above conditions exist for more than 20 seconds.
Typical causes for this code include:
1) O2 sensor defective or contaminated (if incorrect RTV sealant or too much RTV is used, this may happen)
2) Leaking fuel injectors
3) Fuel pressure too high
4) EMI interference from poor plug wires
5) Evaporative Emission system defect
6) TPS and/or EGR problem
7) MAF sensor reading higher airflow than is actually present
