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.

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.

My alarm kills my battery on 2005 camry

Throttle-by-wire systems like yours probably has means there is no physical linkage (cable or rod) interconnecting the accelerator pedal to the throttle body. Instead both talk to the computer via wires. The gas pedal is like a volume control on a radio and can never be felt "moving" when cruise control is engaged and making throttle adjustments such as going up or down a hill like older system did. A bad "sender" on the throttle pedal, bad or loose wiring to the computer, bad computer, bad wiring from computer to throttle body or intermittently bad electric actuator motor on/in the throttle body can all give the symptoms of "no throttle control" you describe. As for the battery being discharged, a bad trunk light switch could keep the trunk light on at all times but you cannot see this when the lid is closed. Immediately touching the trunk light bulb quickly after opening the trunk will tell you if it's staying on, it will be hot as heck. The same goes for the glove compartment light. A keyless entry system always uses power so it can listen for the signal from your keyfob to unlock the door, as does the time clock in dash or radio.

HELP! Problems on my 1997 Grand Caravan P1698, P0138, P0140

you need to go over your entire wiring harness, under the hood and inside the dash. Start with the ground wire on the battery and work your way inside. It sounds like there is a loose ground wire somewhere

92 toyota camry e electrical question

I had the SAME problem with my 1992 Camry LE...except without the water..First, check the back up lamp fuse (there is more than one circuit on that fuse, not sure which). The water would have likely shorted out the circuit. First check for power at the reverse bulb while the car is in reverse (You can do this with the car off) If there is power, check the ground wire, if it is bad...if you splice the ground wire before the connector and run a new wire to a ground in the trunk, then it should work..thats what was wrong with mine..hope this helps
