The stubborn 02 Heater monitor set the very next cycle! Finally we gave up and replaced the sensor. All data indicated that the 02 sensor was working normally. With that said, I vividly remember spending countless hours trying to set an 02 Heater monitor on a BMW. I’m sure the high cost of gas has played a role in motorist’s willingness to pay us to either fast track the drive cycle or determine what is causing the monitor(s) from not setting. I’ve noticed an increased demand for our drive cycle/diagnosis service recently. A knowledgeable technician can determine this by analysing data from the vehicle using a scan tool. There can also be an issue with the way the vehicle is being driven and/or environmental conditions. There could be an issue with the existing sensor. Now to answer your question, will a new 02 sensor solve your problem? (Note: monitor may still run with tank fill between 15% and 85%).ġ) Cold soak vehicle, start and idle vehicle for 4 minutes.Ģ) Drive in-town (stop and go) for 5 minutes, using smooth accelerations and decelerations.Ģ) Drive with a steady vehicle speed above 25 mph for 2 minutes.Ĥ) Smoothly accelerate to a speed between 30 and 40 mph.Ģ) Shut engine off and leave vehicle off for ten minutes.Īssuming that all systems and sensors in your vehicle are working correctly, your mechanic is correct, with normal driving, the 02 sensor motor should become ready. Note: This monitor evaluates EGR flow based on a change of engine roughness (idle stability).Ĭonditions causing un-stable idle will prevent this monitor from running. – A/C clutch, PS Switch and Cooling fans do not change state (turn off).ġ) Idle vehicle for five (5) minutes (to reach closed loop operation).Ģ) Drive with a steady vehicle speed between 40 & 60 mph for 2 minutes. – No misfire temporary (pending) or matured fault present. – Engine must have run at least 90 secondsġ) Idle vehicle for five minutes (to reach closed loop operation).Ģ) Drive with a steady vehicle speed between 30 and 45 mph for 2 minutes.ĮGR System Monitor Drive Trace – Vacuum controlledĢ) Drive with a steady vehicle speed between 40 & 60 mph for 8 minutes.ĮGR System Monitor Drive Trace – Electronic
– Fuel level is between 15% and 85% full.
Specific drive traces for Chrysler vehicles. Note: Due to the limited preconditions provided with this drive trace, NCVECS recommends using the monitor Then I think you need three cycles with car off for an hour, maybe getting through the O2 drive requirements.– Cold start (Note: cold start temperature is undefined)ġ) Warm engine up for five minutes (must reach closed loop)Ģ) Drive (with steady throttle) at a speed between 40 and 60 mph for 8 minutes.Ĥ) Drive (with steady throttle) at a speed above 20 mph for 2 minutes.ĥ) Turn key off, leave off for ten minutes (to run O2 sensor heater monitor). I would go to autoparts place at night, clear codes, and select the EVAP monitor.
