Yes I would agree the trans selector switch has failed, provided the wiring is good.
The license plate lights would be on a different circuit tied into the regular tail lights.

    even with the rear light failure warning light always on?

    That could be for the license plate lights being out.

    The way that system usually works is a computer chip measures the amount of amperage being used in a light circuit. If the amount is low, you get a lamp out warning on the dash. And the license plate lights are on the same circuit as the tail and side marker lamps.

SOURCE: engine service light / 4 codes read description below

P1744 is probably the TC going on the way out. :(

P 340 is probably the sensor itself. Don't get the Dorman one if it is the OHV motor.

P 401 is probably a bad DPF EGR sensor.

SOURCE: Shifting Out of Park Position

Look under the hood where the linkage meets the transmission. If your mechanic just replaced the linkage, he may have not replaced the pivot that hooks the linkage to the shifter lever that sticks out of the trans. Try lubing this pivot up. Also, there may be a bit of adjustment here to line up your shifter. Best idea: disconnect the link at the trans shift lever (at the trans), and work the shifter. If the shifter feels fine, then the link or the trans lever bushing may need attention. Lube it with WD-40.If the problems does not improve, look to see if there is any contamination on the pivots for the shifter assembly in the console. Coffee & soda spills will seize this up and make it hard to shift. Lube this with silicone spray. Hope this helps.

SOURCE: 2000 toyota camry check engine

wires are pinched and shorting together near the left (drivers side) trunk hinge. brake light power is feeding back through the reverse light wiring. this will also turn on the check engine light with a neutral safety switch malfunction code as the computer also sees this voltage in the reverse light circuit. Find and repair the wiring, pull the EFI fuse in the panel under the hood to clear the code. Hope this helps

SOURCE: No Brake Lights, unable to switch from park to drive

It is not the multifunction switch. The power feed goes thru the brake switch before the multi function. You have no power the the brake switch because your shift interlock is not allowing you to shift it. I'll look up the wiring diagram and repost with a solution.

SOURCE: Daytime Running Lights Inoperative 2002 Toyota Camry

[Information] For a 2002 Toyota Camry, the Daytime Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."


2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not burned out. If one burns out, there is a fair chance that the other would have burned out at the same time. Replace as necessary. In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]


My problem was that the test configuration did not have the engine running and parking brake off - Step 1. Problem solved with much thought, repetitive tests on the vehicle and going back to the basics -- what does the Owner's Manual say and where are the applicable fuses and relays located?

PRE-DIAGNOSTIC INSPECTIONBefore diagnosing ABS/TCS, perform a comprehensive visual inspection of system as follows.Check ABS/TCS wiring harness connectors for looseness. Check harness routing; pay particular attention to wheel speed sensor wiring harness routing. Check fuses No. 1D, 5B and 6B in instrument panel fuse block. Check fuses No. 1 and 2 in underhood fuse block. Check brake fluid level in master cylinder reservoir. Check brake fluid level in Pressure Modulator Valve (PMV) assembly reservoir. Ensure parking brake is fully released. Ensure parking brake switch is functioning properly. Always perform ABS/TCS system functional check before using DIAGNOSTIC CODE CHARTSThe EBCM/EBTCM has self-diagnostic capability, which can detect system failures. Fault codes stored by EBCM/EBTCM can be displayed using Tech 1 scan tester. There are no provisions for flash code diagnostics.Begin ABS/TCS diagnosis with PRE-DIAGNOSTIC INSPECTION procedure. If failures are found during pre-diagnostic inspection, perform necessary repairs, and proceed with ABS/TCS FUNCTIONAL CHECK. See Fig. 5 .If no failures are found during pre-diagnostic inspection, go to ABS/TCS FUNCTIONAL CHECK. See Fig. 5 . The ABS/TCS FUNCTIONAL CHECK will either indicate ABS/TCS is functioning properly or direct technician to various diagnostic procedures such as diagnostic charts, symptom diagnosis or BRAKE warning light diagnosis.CHART D - TRACTION OFF WARNING LIGHT ON CONTINUOUSLY & NO DTC SET (BUICK WITH UH8 OR U2A INSTRUMENT CLUSTER)Circuit DescriptionWhen ignition switch is first turned to RUN position, EBTCM goes through a self-test, which lasts 2-4 seconds.

Camry code 1780


This is a problem in the Park/Neutral position switch or wiring.

Apparently Camrys of your vintage often suffer chafing and breakage of the wiring around the rear trunk lid hinge, driver's side. The backup light conductor there chafes and breaks, which the ECU sees as a fault P1780.

The warning light that looks like a car with lights coming from the rear indicates what? This light is just below the check engine light on the dash.


This warning light should indicate that there is a rear light failure. Running lights, brake lights, signal lights, reverse lights. You should check all the bulbs to see if any are burnt out.

1780 code


P1780 Park/Neutral Position Switch Malfunction (Only For A/T)
This code is related to a malfunction with the park neutral position switch, it's located on the transmission.
It maybe easier to get a Chilton manual from the autoparts store to locate the sensor/switch. The book runs about $20.
Replacing the switch/sensor may resolve the reverse light problem also.
