1. What does P0845 mean?
For a 2022–2023 Hyundai Kona in the US, DTC P0845 is referenced in Hyundai TSB 23-AT-010H under a pressure-sensor replacement procedure for the IVT. The bulletin directs use of Hyundai GDS-M to enter a pressure-sensor characteristic value and perform TCU adaptive-values learning after the repair.
2. Technical explanation
Verified evidence identifies P0845 in Hyundai TSB 23-AT-010H as one of the DTCs associated with the bulletin’s “Pressure Sensor Replacement (DTC P0845/P0846/P0867)” procedure. The supplied bulletin excerpt specifies that, during this procedure, a technician uses GDS-M, inputs “76” for the pressure-sensor characteristic value, and follows GDS-M instructions for TCU adaptive-values learning. The provided evidence does not establish the standard text definition of P0845, diagnostic thresholds, or the exact failure mode that sets it.
3. What system is affected?
IVT pressure-sensor / transmission control adaptive-learning procedure. The diagnostic record does not provide a separately verified system name.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
Not yet established by verified evidence.
6. Possible causes
- The verified Hyundai bulletin associates P0845 with a pressure-sensor replacement procedure on the IVT. It does not establish a complete list of causes for P0845.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Arrange diagnosis by a Hyundai-qualified service facility or technician with access to GDS-M.
- Provide the technician with DTC P0845 and reference Hyundai TSB 23-AT-010H.
- Do not attempt IVT pressure-sensor replacement or TCU adaptive programming without the specified diagnostic equipment and service procedure.
10. Step-by-step troubleshooting
- Confirm the vehicle is a US-market 2022–2023 Hyundai Kona, as supported by the supplied applicability evidence.
- Have a qualified technician evaluate P0845 using Hyundai GDS-M.
- If pressure-sensor replacement is performed under the applicable bulletin procedure, the verified excerpt directs entry of “76” as the pressure-sensor characteristic value, followed by the GDS-M-guided TCU adaptive-values learning procedure.
11. When to contact service
Service involvement is prudent because the verified procedure requires Hyundai GDS-M and TCU adaptive-values learning. Whether service is strictly required is not explicitly established by the supplied diagnostic record.
12. What the service center may check
- Verify the stored DTC and vehicle applicability.
- Follow Hyundai TSB 23-AT-010H where applicable.
- Use GDS-M for the pressure-sensor characteristic input and TCU adaptive-values learning specified in the bulletin excerpt.
13. Possible repair or resolution
- The verified bulletin describes a pressure-sensor replacement procedure followed by GDS-M configuration and TCU adaptive-values learning. It does not establish that this repair resolves every occurrence of P0845.
