    thanks very much......i will check all this and let you know what i find...your time and input are GREATLY appreciated....

    Thank you very much for your input on the shift lock problem on the 2005 honda accord. Your suggestion on checking the tps was the trick. The voltage showing on the scan tool was .5 volts to start. Once i lowered it to .3 the vehicle began to shift normally. After performing the idle relearn procedure, the vehicle went back to not shifting out of park. I ended up lowering the tps voltage to 0.2 volts, and so far it seems to be ok..(its my ex-wifes car, so if it screws up again, im sure i will here about it)...but so far, so good.. your site was a tremendous help, and i REALLY appreciate it..Thanks,,,,Tony Revelle.....GMAX AUTO....MT.

    here you go hope it helps!!!!! tps???

    1. Verify the Engine Control Module (ECM) sees the brake switch input and knows the vehicle is in park.

    2. Check the Red/Black wire at the throttle position sensor, if the voltage is higher than 0.49 volts the Engine Control Module (ECM) will not allow the shift interlock to operate. If the voltage is high, verify the throttle cable adjustment and clean the throttle body then if the voltage is correct do a relearn procedure.
    Take off the battery cables and touch them together for 10 in, then hook up the battery and start the vehicle with all electrical loads turned off and let it idle for 10 minutes. If the cooling fans turn on, add that time to the relearn procedure and then verify that the shift interlock will operate correctly.

    3. If the Throttle Position Sensor (TPS) is not low enough and the ground is good. Then either the throttle body will need to be replaced or cut slots in the mounting screws and adjust the TPS sensor. In some cases the TPS voltage had to be adjusted to 0.32 volts for it to operate correctly.

Will not come out of park. Button stuck

Automatic Transmission Shift Lock Control Description and Operation.
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:
• The automatic transmission shift lock solenoid (serviced as the automatic transmission shift lock actuator), as well as the body control module (BCM) and the engine control module (ECM). The shift lock solenoid is located within the floor shift control assembly with vehicles equipped with floor shift.
• The BCM controls the voltage supply circuit of the shift lock control solenoid. The following conditions must be met before the BCM will supply voltage to the shift lock control solenoid.
The BCM controls the voltage to the shift lock control solenoid through the shift lock control solenoid controlled voltage circuit. The following conditions must be met before the BCM will supply voltage to the shift lock solenoid:
• The ignition is in the ON position.
• The ECM sends an input via GMLAN serial data to the BCM indicating the transmission is in the PARK position.
• The BCM determines the brake pedal is applied according the brake pedal position.
Since the shift lock control solenoid is permanently grounded, the BCM supplies voltage to the automatic transmission shift lock control solenoid, mechanically unlocking the shift lever allowing the driver to move the shift lever out of the PARK position as the solenoid energizes. When the brake pedal is not applied, the BCM turns the control voltage output of the shift lock control solenoid OFF, de-energizing the shift lock control solenoid. The de-energized solenoid mechanically locks the shift lever in the PARK position.
During remote start operation, the BCM will de-energize the shift lock control circuit, locking the shift lever in the PARK position.
Circuit/System Description
The body control module (BCM) controls the shift lock solenoid by providing battery voltage to the shift lock control solenoid. The BCM utilizes a smart driver to control the voltage supplied to the shift lock solenoid. The smart driver monitors the voltage and current flow of the control circuit.
Diagnostic Aids
• Use a scan tool to verify there are no brake pedal position sensor and/or transmission internal mode switch (IMS) DTCs set that could cause the BCM not to provide battery voltage to the A/T shift lock solenoid.
• If the automatic transmission shift lock control circuit is shorted to battery positive voltage, the A/T shift lock solenoid will be inoperative. The vehicle will shift out of PARK without depressing the brake pedal.
Your best bet is have it towed to a repair shop !

99 honda accord won't shift out of park

Check your brake light function. If that is at fault then your brake light switch may be faulty. If your brake lights are fine then you may have a faulty shift lock solenoid. Some Japanese models of that era have a button or key slot near to the shift lever. If you depress that then it should manually release the lock and allow you to move through the gears, until you move back to 'P' position at which point it will lock again.

Not shift park

Your gearshift lever (floor or column) has a safety feature that will not allow you to shift out of Park unless the brake pedal is depressed. There is a solenoid on the shifter that is tied to a switch on the brake pedal, which activates a relay that activates the solenoid. Problem could be the brake pedal switch , brake relay, or brake relay fuse (do your brake lights work when you step on the pedal?), or it could be the shifter solenoid or the wiring in between.

How to trouble shoot shifter not coming out of park with the foot on the brake? 1996 Toyota Avalon.

Could be the brake switch or the park lock solenoid.
The brake pedal sends a signal to the soleniod, or interrupts power to the solenoid when depressed.
Something could also be binding in the shift linkage.

Gears won't change. Can anybody provide some useful advice. ?

Automatics have a gear shift safety solenoid that locks the gearshift/transmission in park unless the brake pedal is depressed. This is to prevent people from dropping into a gear from park and rolling into traffic or backing up over someone unexpectedly. When you press the brake pedal you should be able to hear a clicking sound coming from under the gear shift lever. If you dont hear the sound then the solenoid may need to be replaced. The other possibility is needing to replace the brake pedal position switch (usually attached to the pedal assembly or behind the brake pedal assembly) which tells the shifter solenoid to activate when the pedal is depressed.

Shifter is stuck in park. had to remove little cover over hole, by the shifter, to insert key into hole, to get shifter to remove shifter from park. what causes this and is it something i can fix on my...

I believe this vehicle is equipped with a shift lock that necessitates depressing the brake pedal before it can be shifted out of "Park". This is a safety feature designed into almost every car made nowadays to prevent unintended movement of the vehicle when shifting out of "Park". The Shift Lock solenoid is triggered by the brake light switch located near the top of the brake pedal arm. Starting with the "basics", check to see if the brake lights are working (they should illuminate when the brake pedal is pressed. If the brakes lights do not come on. then proceed to check the brake/stop light fuse. Replace if needed. Once the brake lights are functioning, the shift lock should "disengage" and allow you to shift out of "Park" when the brake pedal is pressed. If the fuses are okay, but still no brake lights, then the Brake Light Switch may need to be replaced.

Brake lights working but won't shift out of "Park"? Check for a separate fuse for the Shift Lock Solenoid. Replace if needed. Otherwise the Shift Lock Solenoid may need to be replaced. This will require disassembly of the console to access the part.

When I start engine then depress brake pedal and try to depress shift lever button I can't get it ou of park. This happens 6 times out of 10.

In the area of the shifter (in the center console), there is a shift lock solenoid that is activated by the brake switch. This solenoid prevents shifting out of the Park position unless the brake pedal is depressed. Your problem could be either the brake switch or the solenoid. I would try replacing the switch first.

If you press the Break pedal and the shift button does not engage, Your Solenoid did not activate to release it out of park. either the: solenoid is out - Bent levers - Solenoid harness disconnected - Break activation wire may be damaged. this piece is easy to replace as it sits on the right side (passanger side) of the shift lever. remove center console cover to access the soleniod which is held on by two 10mm nuts. and a C- clamp
