Question about 2003 Jeep Liberty

Open Question

Multiple Sensor Failure

In the last month we've had multiple sensor failures on our 2003 Jeep LIberty. So far they have replaced or performed the following services:

Throttle Position Sensor
Cam Shaft Sensor
Crank Sensor
Multi Function Sensor
Fuel Injection Cleaning
Throttle Bottle Service

What is happening to our Jeep? Will it contiue? How many more sensors are there? Is it time to get a new car? Our 11 year old Saturn is currently more reliable than the Jeep.

SOURCE: I was just told I need crank and cam sensor ,

Hello there, Sounds a bit pricey to me. As far as the fuel injection and throttle body services these are done for maintenance reasons, I am sure it is something you can do when it fits your budget.

Now as far as the cam and crank sensor if there is a problem with one of these sensors you will have a drivablity problem such as hard starting and a lot of times shutting down after the car warms up.

If your not experiencing any driveability problems with your vehicle I would suggest having the computer resset and see if your light comes back on or if they were false codes.

Good luck and I hope this helps you, Allen

My 2003 jeep liberty wont start without keeping foot on gas. Had to drive 2 miles home without taking foot off gas luckily made all the lights


Sounds like it's flooding itself. Maybe the choke is sticking on.
Check the air filter and make sure its not plugged.

I don't think the fuel pump. Sounds like the crank position sensor. That, or the camshaft position sensor. The computer uses the cam position sensor to know when to pulse the injectors. The crank position sensor provides the information for spark timing. If the sensor fails, the computer won't signal the ignition module to create spark from the coils. Crank sensor failure is pretty common on earlier jeeps.

Jeep Liberty 2004 sport gas cap not sealing


You can get the silicone grease at automotive and hardware stores. Apply to rubber seal on cap about every 2 to 3 months. This will ensure a seal so that the engine light doesn't come on. Worked great on My 2008 Liberty.

My 2003 jeep liberty is showing a P0300 code. In the past we have replaced the computer and multiple vacuum hoses. I think it is prolly another vacuum problem but I dont know where to start. My...


it is multiple misfires on cylinders(random). this can be due to your vacuum leak over somehere on intake manifold. you can diagnose leaks by spraying brake pad cleaner on engine block when it is running. one location at a time. if idle speed or sound changes you will understand that there is a vacuum leak and it is sucking excess air from there. if it is only a misfire, this can be a micro crack on intake manifold.

Did they give you the error codes, or just tell you that it was the multiple engine misfire, evap and TPS? If they didn't give you the codes then I would take it to an autoparts store and have them read the exact codes. Replacing the heads because the valves are sticky is questionable in my opinion. Dealerships sometimes are quite unreasonable when it comes to replacement parts. Plus they seem more apt to take advantage of a KNG (Know Nothing Girl) than most shops.

I would like more information about the engine combustion cleaning that they performed!

You might also want to go to the http://www.jeepforum.com/ and post it there. They have multiple Jeep specialists that might be able to steer you in the right direction.

Hey there, 2005 Hyudai Santa Fe, with multiple codes. p0320, p0300, p0301, p0302 thru p0306. any ideas please? Thnaks' Greg


Each one of the codes indicate misfire, except p0320.

1. Check IG failure sensor (1) Connect IG failure sensor and PCM connector (2) Engine "ON" (3) Check that RPM meter on instrument panel is operating correctly and the signal waveform of IG failure sensor at terminal 4.

m0320-8.gif (4) Is the IG failure sensor normal? YES ??¶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure. NO ??¶ Substitute with a known - good IG failure sensor and check for proper operation. If the problem
