My check engine light came on today and while driving, the idle (RPM's) were very high. At about 80KMs, it was about 3500 and when I accelerated, the engine would race along with the RPMs. While stopped, idling seems fine. I couldn't get over 80KMs/Hr without the idle going too high.
What it could be? Haven't had time to check codes as it is long weekend and garages are now closed till tuesday.
I was able to quickly diagnose the problem with our 99 T&C LXi w/3.8L.
Problem: No speedometer, wouldn't shift, check engine light came on.
Many posts suggested speed sensor. There are actually 2 of them. An input and an output. Both cost approx $20 each.
By removing the aircleaner box assembly, I had the best (relative word) access to the sensors. A 1" socket w/3" extension did the trick. I understand the access for 2000+ models is different.
I have an 02 Dodge Caravan 3.3 L Flex . It had initially stalled and wouldn't start. Check engine light was on. Had it towed to a Cert Mech. He said it needed a "Major" tune-up. I let him do this. It included: New Coilpak, plugs, plug wires, cam-sensor, crank sensor. That's what was on 1st invoice.
It started, but was still running very rough. He then recommend a new PCM. After choking on his estimate, and paying the initial invoice, I decided to let someone else have at it. Mech # 2 installed a "Rebuilt" PCM, New Battery, and a PCV Valve.
It runs good now BUT, ...It has this weird idle Misfire. The only time it happens is at a stop light when at idle. And it doesnt do it all the time. This check engine light is not on... At this point, all I want to do is sell it.I have over 1K in repair costs and still can't get rid of this misfire.
I have a 96 Grand Voyager that had had sat for a year undriven or started due to being out of state. It ran like a champ when I parked it. Now I charged the battery and went for a drive on the freeway and my check engine light came on and started blinking. I had the code read it came back with 2 codes a P0306 and a P0300. I noticed that the cylinder 6 spark plug wire was arcing on the core support. So I replaced all the plug wires and spark plugs with Champion platinum spark plugs. I cleared the codes and took it on a test drive and the P0300 code came back. Is there anyway the old gas is causing the random misfire? or what else could it be?
View 1 RepliesI have an engine noise on my 2000 Dodge Caravan with the 3.3 engine. It sounds a lot like the grinding of a rotating part. It occurs at start up, momentarily, then goes away. If I drop it in gear and start doing low speed maneuvering in the driveway, it comes back. If I turn on the AC it comes back. In all cases, the noise goes away at around 1200 rpm.
The noise occurs again, when I shut the engine down.The engine performs and runs smooth and normal otherwise. No stalling, stumbling, or bad gas mileage to report.
I can "feel" the noise with my hand, when I put my hand on the ac compressor bracket, or the intake manifold, or the valve cover. I've tried the listening through the stick method, and it seems to be coming from the front area of the engine. But I can't be sure. It is something internal. Let me describe:
I thought it was my AC compressor or clutch going bad. The fact that my AC had stopped working well, and was making jet engine noises at high rpm supported me decide this. I replaced the compressor. The AC works great now, and the jet engine noises went away. But the grinding noise is still there. As described.
I wishfully thought it was the belt tensioner or idler pulley. I replaced both of those. Noise still was there. I pulled off the serpentine belt, and started the engine. It made the noise, very briefly as it started, then went away completely. It made the noise again briefly as I shut the motor off. So it's still there without any of the accessories turning.
The noise is loud and obnoxious at idle when under load. It just can't be good. I've read theories about similar sounding problems, saying they could be loose timing chain, bad oil pump, slapping pistons, crank journals, flexplate/flywheels cracked.
I'm going to try doing an oil system flush, and then I'll change it out with a little thicker oil. See if that makes any difference in the noise. Currently I'm running 5w-30 Mobile 1. I think. I'll let you know if it changes anything. I'm also thinking I want to make a short video of the car idling and making the noise for my video camera. I'll post that on youtube and link it here.
1st problem is shifting from 1st to 2nd and sometimes from 2nd to 3rd though, 2nd to 3rd is not as bad as from 1st to 2nd. It stumbles and gets really bad if I don't let up on the gas. After the initial shudder it will go into 2nd just fine. I also have to gun the gas a little bit when I first start the car, or it will just sit there and idle and never go into gear.
2nd and more annoying is that it stalls after driving around a bit. It happens on freeway or city. It doesn't stutter or anything the rpm's drop to 0 and it just stalls and won't start up for a 5 - 10 minutes or so.
Codes pulled are P0731, & P0736. The transmission was replaced about 2 years ago with a refurbished one. Could it be going out again already? The guy at Autozone suggested replacing the TSS (Transmission Speed Sensor?) to see if that was the problem. I have not done this yet, but plan to.
My wife has a 2000 t&c with 150k on it its a fwd with 3.8 and about a month ago while driving we noticed the rpms will jump up 400 and go back, with cruise control on or off being held at a consistent speed. and about for days ago it started shifting late. Still has all gears fluid looks o.k. and is full no check engine light .
I am hearing transmission solenoid, tps sensor, input sensor, output sensor, tcm, iac, map, or egr are all possibilities or a rebuild . Or simple as a flush.. tonight i went out n started it it idles around 800 tried to hold it at 1200 and it would for a second and drop back to 800 with accelerator being slightly held. Not sure if related. Just observed it..
I had to replace the water pump on my dodge Grand Caravan, which was challenging, but I got it done. But now the engine light is on.... why would that happen? I did take off the filter hose, and unplugged the cord to move the air filter housing, but I plugged it back in when i re-hooked everything up. So now I am nervous that i did something wrong. Why the engine light would come on and stay on? water pump works, put coolant in etc.... no leaks.... so now i just need to figure out the engine light.
View 9 RepliesService Engine light came on couple days later turned off, came back on today & vehicle stopped shifting into 3rd. Later this evening was driving it and power steering went out, ABS light came on, temp gauge jumping from hot then cold. When Service Engine light came on originally took to autozone. these are the codes given:
P0700
P1776
P0420
I have read problem could be input or output sensor which are $17 bucks each. Going to try those...
Mileage is 145,000
Went to the dealer because my idle was running both too low and/or too high, check engine light came on.
1) Replace air intake manifold because air flow flap is faulty.
2) Oil leak out of upper and lower timing belt covers - need to replace gaskets.
3) Missing!!! the high note horn
I've just done an engine swap to my 2000 GTS Celica. The new engine seems to run nice and tight and smooth and everything but I can't seem to bring the idle down. It stays revving at about 2000 RPM and the check engine light is on. The engine is from Japan and only has 35,000 kms. on it.
View 14 RepliesI took the van on a road trip and the engine seems like it wants to stall at lights. the idle stays at 500 rpm or so most of the time while at stops. there appears to be no way to adjust the idle and there is no Czech injun light on.. what could the problem be? the engine is a 3.8l
View 4 Replies2007 Grand Caravan 3.8L 100K mi. New noise chirp-chirp-chirp Sometimes an intermittent rumble at idle seems to be in synch with the serpentine belt especially when the A/C is engaged. I changed the serpentine belt which did not look bad and did not emit the noise. Noise seems strongest at the alternator when I use a stethescope. I noticed the pulley seems a little loose with the belt removed, but the bolt is tight. This alternator has an overrunning alternator decoupler (OAD) pulley so maybe the loosness is normal. The bearings seem smooth when I spin it with the belt off, and it charges fine. Just the noise is bothersome. Do I need to change out the alternator or just the OAD pulley?
View 2 RepliesMy 2007 Dodge Caravan has only one working headlight, the passenger side does not work on high or low beams.
At this time I'm wondering if the problem is in the headlight plug itself, because there are no other complications other than the passenger side not working.
The light did work at first on high beams but now not at all. replacing bulbs makes no difference. There is some brown discoloring on the white strip on the plug face, nothing like this on the driver side.
Also hoping that the problem is not the relay or front control module.
P0032 Oxygen Sensor Heater Circuit High Voltage (Bank 1, Sensor 1)
I have read that in 2005 chrysler changed the ohms levels for the oxygen sensors and may need to have bcm reflashed to get a new oxygen sensor to work wheither its dealer item or not, is this true if i were to buy a mopar oxygen sensor? aftermarket is out of the question being the ohm readings would require me to spend some time at the dealer. is this code a defective sensor? or could it be related to the thermostat being faulty? am not low on antifreeze and temp gauge reads normal.
On my 2005 3.3L Grand Caravan the ABS light keeping coming on. I inspected the sensors for the front and used my compressor to give them a quick puff of air to get rid of dust. The light went off for about 5 days. Now it is back on.
How does one read ABS codes? If I knew for sure that the problem is a speed sensor and which one I could clean or replace the faulty sensor.
If I clean to sensor are there any special precautions I need to take? As far as I could see they didn't look very dirty.
Intermittently the ABS Light is coming on. 84,000 miles.
Brakes have been changed once, 10,000 miles ago.
Minor clunk sound when light is on.
Light goes off after van has set, brakes work fine at that point.
ABS light is on and the auto trac is off and will not turn back on. What this could be?
View 2 RepliesChanged oil on the 2014 grand caravan, replaced the filter. afterwards the oil light comes on at low rpm goes out when u accelerate, and the engine light is on. Took it to autozone, it is saying, that the oil sensor switch is stuck.
View 5 RepliesI start my van and open the hood to check Coolant and I notice gas spilling out engine and running down the side close to my power steering pump. So I stop the vehicle and notice gas sprayed on different parts by the back spark plugs and a little area by sensor.
View 3 RepliesHad a first-time issue with my car today. Background, 2010 II bought in June, just short of 15K miles, never had any kind of mechanical issue.
While en route to work this morning, I was about halfway into my 15 minute drive to work, when I noticed my engine was idling very high, I would guess 2500 rpms. It started doing it while I was driving around 35 MPH, then continued doing it while I stopped at a traffic light, and continued when I continued driving to a speed around 50 MPH. The high idle while stopped was not transferred to the wheels, so it was not a safety issue as it would be in other cars.
When I got back up to 50, curious to try something, I hit the ECO mode button and the car returned to normal. I took ECO back off and the car was still fine. I had no further problems.
I would point out that this morning was about the coldest temp that the car has experienced. Outside temp ranged from 7 to 10 degrees.
