M.I.L. "ON" DTC P0346
Component
ENGINE ELECTRICAL
Models
'04 Camry, Highlander & Solara (V6), and
'05 Camry & Solara (V6)
REVISION NOTICE:
July 04, 2005: Calibration Information Chart has been updated.
Previous versions of this TSB should be discarded.
Under certain driving conditions, some 2004 model year Camry, Highlander and Solara vehicles and 2005 model year Camry and Solara vehicles equipped with V6 engines, may exhibit a M.I.L. "ON" with the following DTC:
- P0346 (Camshaft Position Sensor "A" Circuit Range/Performance [Bank 2])
The Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified to change this condition.
NOTE:
- Version 12.01a or later Diagnostic Tester software is required to perform this procedure.
- Before proceeding, verify the ECM (PCM) calibration has NOT been updated by checking for the Authorized Modifications Label (shown in Step 1 of the Repair Procedure).
APPLICABLE VEHICLES:
- 2004 model year Camry, Highlander and Solara vehicles equipped with V6 engines.
- 2005 model year Camry and Solara vehicles equipped with V6 engines, and produced BEFORE the Production Change Effective VINs shown below.

CALIBRATION INFORMATION:
NOTE:
- Although the calibration description in the Calibration Update Wizard and on the Diagnostic Tester reads "04 (and applicable model), these calibrations apply to 2004 and 2005 model year vehicles produced before the Production Change Effective VINs shown in this TSB.
- 2004 model year vehicles, which have been flash reprogrammed using the procedures in this TSB, will contain upgraded 2005 model year OBD II logic. Refer to the 2005 model year Repair Manual information on ETAS when checking Powertrain Diagnostic Trouble Codes (DTCs) on 2004 model year vehicles that have been reprogrammed.
REPAIR PROCEDURE:
1. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if ECM (PCM) calibration has been updated. If not latest ECM (PCM) calibration - go to step 2.
2. Connect the Diagnostic Tester to the vehicle and select CURRENT ECU CAL from the ECU REPROGRAM MAIN MENU. Determine the vehicle's current ECU calibration.
- The sample screen prints seen are the 12.01a software version, and may differ from subsequent software versions.
NOTE:
- If Calibration ID matches "Previous Calibration ID" as shown in Calibration Identification Chart, proceed with flash reprogramming.
- If Calibration ID matches "New Calibration ID" as shown in Calibration Identification Chart, this vehicle has already been programmed.
Refer to ETAS for diagnostic procedures applicable to any stored DTCs.
3. If ECU calibration ID is not the same as the "New Calibration ID" listed previously, proceed to Flash Reprogram ECM (PCM).
FLASH REPROGRAM PROCEDURE:
Camry and Solara:
Flash Reprogram ECM (PCM)
1. Remove the 10A ECU-IG fuse from the Instrument Panel Junction Block assembly. This action prevents possible activation of the ABS relay, resulting in ECM Reprogramming failure.
NOTE:
ECU damage may occur if 10A fuse is NOT removed.
2. Follow the procedures outlined in TSB No. 0941, "ECU Flash Reprogramming Process," and flash the ECM (PCM) with new calibration file update.
3. Reinstall the 10A ECU-IG fuse in the Instrument Panel Junction Block assembly.
4. Follow the procedures outlined in TSB No. 2133, "Entering VIN During ECM (PCM) Replacement and/or DTC P0630," and write the VIN to the ECM (PCM).
5. Enter the required information on the Authorized Modifications Label and affix it to the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the PDC, P/N 00451-00001-25.
6. The repair is complete. Test drive vehicle to confirm normal operation.
Highlander:
Flash Reprogram ECM (PCM)
1. Follow the procedures outlined in TSB No. 0941, "ECU Flash Reprogramming Process," and flash the ECM (PCM) with new calibration file update.
2. Follow the procedures outlined in TSB No. 2133, "Entering VIN During ECM (PCM) Replacement and/or DTC P0630," and write the VIN to the ECM (PCM).
3. Enter the required information on the Authorized Modifications Label and affix it to the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the PDC, P/N 00451-00001-25.
4. The repair is complete. Test drive vehicle to confirm normal operation.
NOTE:
Issue of this Technical Service Bulletin is to ensure that proper repair information is available. IT DOES NOT CONSTITUTE AN AUTHORIZATION FOR REPAIR. Normal provisions of the formal warranty policy, as applicable, will apply.
