Default Can my car detect when its in gear??

Well a few months ago my crx ran plowed down a fence thanks to my brother leaving it in gear and my remote start. My question, is there anyway the car can detect when its in gear so I can tap into it and make it inhibit the remote start module? TIA

The only gear I can think of would be reverse. Why-because the backup light switch can be tapped.

Yeah I thought about that one but it would only work in reverse. I'm thinking there has to be something because on the VTEC engines how do they detect the car is in neutral so as not to engage vtec....

Are you sure that it detects that the car is in neutral or just that the car isn't traveling at least 20 MPH for the VTEC to cross??? Anyone??? I'm not sure either.

VTEC doesn't know what gear its in. For VTEC to work you have to be moving something like 15-20mph so obviously the car would be in gear. Lets say you are letting the car roll at a speed of 20mph you obviously have to be in neutral or at least have the clutch pedal pressed down to roll at which point your rpms would only be 800 and VTEC won't engauge at that rpm anyway. So no VTEC does not know what gear your in.

'89 and later Hondas have a neutral safety switch to alleviate this problem. Your '88 does not. Perhaps there is some way to install a neutral safety switch on an '88 model? Dunno, never heard of anyone doing this.

Other than reverse there is no way for the tranny to know if it's in gear. I have a pretty simple design to make it so you have to do a few things before you can remote start it that make it as close to imposible to start it in gear as possible. If you want i can draw it out and email it to you.

Remote starts for manual transmission cars have a few features others don't.

For it to work, a few extra steps must be used.

First, when you pull up to your parking space, you engage the remote start so the engine keeps running after you remove the key.

So you remove the key, get out of the car, and close the door with the engine still running.


Safety #1 (Key removed - door closed - engine still running)

After you leave the car and close all the doors, you hit the button again to stop the engine , got it so far?

Safety #2 (Engine was running - doors are closed when engine was stopped via remote)

Safety #3 If any door should open between the time the engine was shut off remotely and the time you press the button for a remote start, the remote start will not function. (It figures that since a door was opened, someone could have possibly put the car in gear)

If a window/sunroof is left open, that could be a problem......


To make it short, in your case.

Get out of the car with the engine running and lock the doors before turning off the engine. (A very good practice to do with a remote start vehicle)
Hook up a relay to break the remotes' power circuit and not reset if the dome light comes on/off.
Don't ever give anyone else the remote, ever. If you let others drive your car, give them just a key, NO REMOTE
Lock your cars doors everytime you leave the car.

Maybe getting the correct remote start unit would help

I have a Clifford G4 on both of my cars (both are manual trans.) with the Intellistart 4 module. It does exactly what the other guy said,

Safety #1 (Key removed - door closed - engine still running)

After you leave the car and close all the doors, you hit the button again to stop the engine , got it so far?

Safety #2 (Engine was running - doors are closed when engine was stopped via remote)

Safety #3 If any door should open between the time the engine was shut off remotely and the time you press the button for a remote start, the remote start will not function. (It figures that since a door was opened, someone could have possibly put the car in gear)

And as for the other guy that said "why not just walk to your car and start it" there are a couple advantages of being able to start the car remotely.

On my cars the HVAC controls run while the remote start is active, therefore during the winter I leave the car with the defroster on so I can start the car from inside the house ahead of time and come out to fog free windows and comfortable cabin tempature. Vice versa during the summer time, leave the car with the A/C on and start the car a couple of minutes before you leave the house and you've got yourself an ice cold car to come out to instead of a fire pit to get into.

There is also an additional advantage to the Intellistart 4, there is a "quick stop" feature that allows you to leave the car running take out the keys and remotely lock the door. "say you were just gonna run into the store and grab a quick something, you can leave the car running lock the doors and take the keys with you, run in and grab your stuff, come back out unlock remotely put the keys in and drive away.

THere is also a "vacation" feature, that automatically monitors the level of your battery, so say you're on vacation or haven't started the car in a while and the charge the battery is carrying drops below a certain level, the alarm will start the car and let it run for a pre-determined amount of time to prevent the battery from completely dying.

And it can also function as a turbo timer for all you forced induction guys.

I highly recomend it.

well if you have any electronics skills it would be relatively trivial to build a simple circuit that would shut off the car under certain circumstances if it detected signals from the VSS (vehicle speed sensor). that way the worst thing that would happen is it would probably move about a foot or two at the most. not ideal for a garage, but it would be better than nothing if it were parked in the driveway or street. just an idea that popped into my head...other than that, there is no gear sensor that you could tap off of. i suppose you could also wrig up some kind of switch on the shift linkage itself...but it would require a lot of work in my opinion to have it accurate and reliable.

How about the emergency brake. Everyone doesn't live where its perfectly flat. Car will not start and drive off in gear if the emergency brake is set.

I can hook it into the handbrake so the car will not start unless its pulled but I've tested cranking the car while in gear with the handbrake to its maximum and it still got up and went
