Prius (2004-09) :: Hybrid Vehicle Immobilizer / Theft Deterrent Indicator Light Came On
My 2005 prius with 81k on it just had the Hybrid vehicle immobilizer / Theft deterrent system indicator light spontaneously come on during a road trip where she was heavily loaded for the very first time since I have owned her for over 10 years. I stopped at a rest area and when I got back in it was on...immediately my batteries started draining. They are in 50wh mode which has never happened before, and charge will driving, but if I shut down for even a few minutes they are drained again. The dealer told me this was nothing to worry about and that as soon as they fully charged this would stop.

We have a 2004 Toyota Prius, with the smart entry and start system. A few days ago the (factory) theft deterrent alarm started going off at random, when there are no obvious causes. Last night it went off 3 times in the middle of the night. I won't have time to get it to a dealer in the next few days.
Is there a way to defeat the theft deterrent system and still have the car be drivable and lockable? Somebody suggested I could lubricate the door lock switches which may not be making good contact. Or, the fob battery may be low. (Can't check either till my wife gets home with the car.)
Prius C :: Theft Deterrent Indicator Started Blinking
I have a 2012 Pruis C II which has a smart key and I just noticed that the Theft Deterrent indicator, page 110 in the owner's manual, has started to blink whenever the power is off. I have not noticed this in the past 5 months. Could it be that I never noticed it before or it has just started to work or?

When you start the car the theft system light comes on and then the car stalls. This has been a continuous problem for about two years. I can't find any pattern to when it does and does not start. Sometimes it will start again the next try, sometimes 30 minutes, sometimes I have it towed to the pontiac dealer after a week of not starting. Recently I have had the cluster sent out twice to check for problems, a new lock cylinder, and the bmc replaced. (about $1,150 total) This was done by a certified pontiac garage and the problem is still not fixed so I dropped it off again last night. Any suggestions? Also is there a point where I should get reimbursed for having parts replaced that were not broken? I have to believe that if the problem is still happening then there was nothing wrong with the lock cylinder or the bcm.

Just found out I have a problem with my evap system (97 Grand Prix GTP). My SES light comes on intermittently. Not sure what the number of the code is, but my mechanic said it was because the vacuum was too strong (not a leak). He said could be from a kink or clogged hose. What this could be? Are the hoses and canister easily accessible for me to check?

About a month ago I had my SES light go on and I took it to the auto parts store and they said it was a small emissions leak. I am not sure of the code though. I took my car to the shop and they said that a sensor that had something to do with the exhaust was bad or unplugged.
My SES light came back on about about a week ago and I had it tested and it said the same thing. "Small emissions leak" This time I got the code and its P0442. The shop is closed today and tomarrow so what and where the sensor is located? Or if its the same thing?
Grand Prix :: 2002 GT Started Then Died - Security Light Flashing
Having an issue with my 2002 GP GT. I started it, but then it died after a couple of seconds while the "Security" light was flashing.
I actually had both original keys with and tried each to no avail (same thing: starts, but engine kills after a few seconds). I checked the PassKey III fuse and even replaced it - still no luck.
Called two different dealer service departments and they suggested turning the key to the "ON" position and leaving it for 15 minutes. I tried this 3 times and still the same issue.
I understand this can be a VERY expensive repair as I've read it requires replacing the ignition module and perhaps the Theft Deterrent Module. How to at least temporarily by-pass or reset the system so I don't have to get it towed (of course it's no where near my place).
Grand Prix :: 2002 Pontiac - Gauges Flipping / Air Bag Light Flashing Now It Won't Start
2002 Grand Prix, 3.8L na motor, 187K miles. It was running perfectly until 4 days ago. initially, odd gauge stuff and flashing air bag light, then very, very slight engine skip with the tach gauge flipping around. 2 days ago, harder than usual starts ( a couple of seconds cranking instead of instant starts ), 1 day go, longer cranking in the morning, worse stuttering at highway speed. Afternoon, very hard start, stuttering right away, and then it would hardly start and quit after seconds. Gauges flipping and relays buzzing under the dash.
I had it towed home. Moving the key to run I didn't hear the fuel pump running. Checked the pressure at the rail, zero pressure. I removed the relay and jumped it to run the pump at high pressure. Fuel pump ran, pressure was 50-60lbs. Reinserted the relay, tried to start it and no change. I couldn't hear the pump running. Removed the relay and jumped the pump again, left it running and tried starting the car. Also no start.
I'm thinking it may have something to do with the ignition switch, PK3 system, BCM or PCM although I'm not sure which way to go with testing. I'm going to re-check the fuel pump and then start taking ignition switch out.
Grand AM :: 2003 Service Vehicle Light Stayed On After Oil Change
I have a 2003 pontiac grand am gt 3.4. About 5 days ago my change oil light came on and did not have time to do it at that point. Then 1 day later my service vehicle soon light came on, I thought it was due to the change oil light being on. Then next day, I changed my oil and pushed the reset button in, let the light flash then held it in until the change oil light went out. But my service vehicle light stayed on, took it to AutoZone and they put the scanner on it and the scanner did not show one thing wrong. So I had him clear the code and the light stayed of for about 10 seconds then came right back on! Is it a faulty issue or what?

I had the service vehicle soon light come on the other day and it took out the gauge back lights, fog lights, and tail lights. Also, when I used to lock and unlock the car with the remote the exterior lights would flash, now they don't. I check all headlights and tail lights and none of them are burnt out.

95 Grand Prix Ignition Cylinder - Cannot Turn Key

View 1 RepliesGrand Prix :: 99 GTP - How To Lift / Hoist Engine Out
I'm pulling the engine to overhaul. I've borrowed a hoist and think I'm ready to lift the engine out, but I don't know how to strap the engine to the hoist. I first thought of using the brackets with the eyelets bolted to each head and bought chain and hooks. But I had to remove the rear bracket so I could remove the rear exhaust manifold so I could remove that darn rear engine-transaxle bolt. (That really bites because I want to have the exhaust manifolds on when dropping it back in.)
Are those brackets intended for lifting the engine? If so, I could reinstall the back bracket and give it a go.
Searched the internet for info but didn't find much. Did find a 3800 being lifted with two straps completely under the engine.
Also, the engine-transaxle joint hasn't cracked open yet. I'm guessing it's because they're stuck after 198k miles and will eventually separate. But I did not find one of the engine-transaxle bolts mentioned in the 98 FSM: front lower (#1). I don't see how I could have missed it ; maybe the 99 doesn't have it?

I have a 2000 Grand Prix with a 3.8L engine that will not start. When I turn the key to the run position, the headlights and the dash lights come on, but when I turn the key to the start position, the lights go dim and nothing happens. No sound from the starter. I checked the battery and the starter and they are good. I installed a new positive battery cable. Still works the same. Not sure what else to check.
View 13 RepliesGrand Prix :: 2004 - RPM Will Drop All The Way Down And Stall
When you are accelerating anywhere from half to full throttle it may cut out at any given time. The RPM will drop down, it may bounce up and down for a bit and recover, or it will drop all the way down and stall. If you let off the gas it may or may not recover. If it stalls so far from the tests I have done if you never shut the key off it will never restart again. If you shut the key off and wait from 5 to 10 minutes it will all of a sudden restart normally like nothing ever happened. If you try to restart it immediately even if you shut the key off and back on it will not start.
When it does not start when I am attempting to start: Fuel pressure according to my gauge is between 55 and 60 psi. Inline spark tester shows that it is getting a spark. Engine sounds normal while cranking so in other words compression sounds normal. I have an LED test light rigged up showing when an injector fires, and it does show electrical activity going to the injector when it opens (flashes). Only clue is that it SEEMS dimmer when it wont start, but I have no clue if thats how it normally is on start up. Its only a slight difference from the brightness of a normal idle brightness. I have a snap on scanner hooked up, nothing that I know of looks abnormal in the data and it will not throw codes when this happens.
Parts I have changed or cleaned so far: Changed the fuel filter, crank sensor, cam sensor, ignition module, and MAF sensor. Cleaned the throttle body. When the car is working normally it runs strong, good power, smooth. Starts great normally.
Grand Prix :: Harsh Shifting From 1st To 2nd And Then From 2nd To 3rd Gear
What may be causing my car to harshly shift fron 1st to 2nd and then from 2nd the 3rd. One solution some one had was to replace the:
"TPS (throttle position sensor). The other reason for hard shift is a worn Boost valve and will need to be replaced, or a faulty transmission fluid EPC (electronic pressures control valve). Both Boost valve and EPC are located in the Valve Body and can be replaced with out dropping the valve body, but have to drop the transmission pan".
I did just recently top off the tranny fluid because it was running a bit low but there is no leak....
