Trying to find the bank 1 sensor at the top. Need to know how to access the sensor.
A new issue came up. The van now takes random times not to start. The mechanic, the girls, took the van to told them it was having the same symptoms as a "Neutral Safety Switch." I placed an order on Amazon.com. The part arrived on the morning of Thursday, May 28, 2020.
On that same morning, I replaced the above-listed switch. Upon completion of the job, the van started without any issues. I tried numerous times to start the Sedona van. I had no problems at that time.
On the evening of Thursday, May 28, 2020, Sylvia drove the Kia Sedona to Wal-Mart. When Sylvia went to leave that same evening the Sedona didn't want to start. According to her, it took more than one try to start the engine.
After receiving this information, I began researching different possibilities. I have narrowed it down(in theory) to two possible culprits:
1. Worn out Key: Sylvia's ignition key is wearing down and not making full contact with all tumblers.
2. The Ignition Switch: The ignition switch is altogether wearing out and is not making the proper contacts every time.
To test each theory:
1: Worn out Key:
Test: Compare Sylvia's and Amanda's keys. Try Amanda's key in the ignition.
Repair: If the key is the problem, then take the good key to Wal-mart and have two new ones made.
2. The Ignition Switch:
Repair: If the key is NOT the problem. Connect the OBD!! Scanner to the Sedona. See if there is a failure code.
