Hi, I have a 2001 Chevy Astro with 85000, and I have two problems. First, I have had a recent issue with the turn signals not blinking when braking. That happened to me this morning. Second, I had an error code which came up when my Service Engine Soon light came on. The code is P0341, and it says, 'Camshaft Position Sensor A - Bank 1, CKT Range/Perf'

Anyone know what to make of either of these issues?

Thanks, J

Are you saying the turn signals work fine when you don't step on the brakes?

The brake lites and turn signals use the same voltage circuit, just not at the same time. That circuit is controlled by the turn/hazzard switch. When you engage the turn indicator switch, it kills the brake lite on that side only.

Yes, I am saying that the turn signals just stay in the 'on' position when hitting the brakes.

Thanks,

Jeremy

In the rear, the brake lites and turn signal use the same bulb fillament, they can't work at the same time.

When you use the turn signal lever for a left turn, you won't have a brakelite on the left side, you should have turn signal, though. You will still have brake lites at the high-mount brake lite and brake lites on the right side.

Maybe I misunderstood your question, somehow?

I think I didn't communicate it well.

My signals don't blink, but just light up when applying the brake pedal. Otherwise, when I am coasting or hitting the gas pedal, they blink like they normally should. This problem happened just yesterday on the way into work. Any thoughts? Could it possibly be that one of the bulbs is going (or is already shot?)?

Are you saying none of your turn signals work, front or back, when step on the brake?

You may have to check the turn/ hazzard switch.

Yes, the arrow stays lit up, but it doesn't blink when I brake.

Otherwise, it seems to blink just fine.

Thanks!

Any thoughts on the error code P0341?
Do I just have to replace the camshaft position sensor?

Thanks.

Looks to me like your going to have to check the circuits at the turn/hazzard switch.

As far as the cam sensor, that's a hall switch, three wires, ref voltage, ground, signal. I'd check those before I did anything else.

I have a 2001 Chevy Astro 2wd 4.3L 177,000 miles.
The brake lights do not work. The center brake light works, hazard lights do not work, turn signals do work. The harzard fuse is good, all bulbs are good. And I have changed the brake light switch on the brake pedal. I think the hazard light switch is bad. Is there a way to check this without buying a new and place it? The hazard switch cost $301.00. Thank for your help.

Have you tried scaning for codes.

I believe your right the hazard switch may be bad. ? Does the brake lites ever work when the high beams are on.

Also you can find the switch at a much cheaper rate I'm sure check around at your local automotive stores.

SOme will even let you buy the part and if it dose not work return it for refund of course that is as long as it works.

I hope these suggestions help

let me no what happens

Hi I have a 1998 Chevy Astro Van with a 6.1 engine and Automatic, It has 200,050 Miles and I had a trailer hooked to it with maybe some bad wires but im not sure, so any way the brake lights quite. The over head brake light comes on and the turn signles do work however the hazared seem to require a wiggling of the red swith in the up position to work but wont stay on. I have chaned the two bulbs and checked all the fuses, can you head me in the right direction. Thanks

My brake lights are not working. I have replaced the fuse & the bulbs but no go. I read that it might be the brake light switch. Does that sound right? If so, how do I replace it?

Before you replace it-check for power at the orange wire on the brake switch-No power check stop/hazard fuse 20amp. Power there-jump connector with a small wire then check the brake lights -is it On? If so-replace switch and adjust it. Brake lights don't come on when jumpered -you have a problem with the turn/hazard switch power has to come from there to get to the brake lights.

The high mount brake light has a different circuit. If this light is coming On and not the others were right back to the turn/hazard switch-Now if this light is not coming On -its the brake switch-
