Record by record
44 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

- says it did not fix it19
- result not stated13
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

3CorrectionNot repaired
What the documents say to do
Unwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)Confirm
- The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.
Repair
- Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
- The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.
Caution
- Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.

- Fault
- THE CONTACT STATED THAT WHILE THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE JUMPED AND HESITATED WITHOUT WARNING.
- Remedy
- THE VEHICLE WAS NOT REPAIRED.

Normal Transmission Shift and Throttle Response Delay
1Fault
- A sag or hesitation may be noticed when coasting at low speeds of less than 24 km/h (15 mph) with a closed throttle and then aggressively applying the throttle.
- With an automatic transmission, after a hard complete stop with a closed throttle immediately followed by an aggressive throttle opening, the downshifts may not be completed by the time the throttle is opened.
- A sag or hesitation may also be noticed while cruising at highway speeds and then aggressively increasing the throttle, forcing a down-shift.
2Finding the cause
Possible causes
- In this maneuver the throttle blade is opened slowly for up to 0.7 seconds, even though the accelerator is applied aggressively, to help minimize driveline lash and clunking.
- As a result, approximately 0.5 seconds of zero torque may be commanded to allow the shift to first gear to occur.
3Correction
Caution
- All of these conditions are a result of Torque Management and should be considered normal; no repairs should be attempted.

- Remedy
- This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use. Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement. This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days.
