Why is my engine light on?

For the past few weeks my engine light has been coming on intermittently, but the last 2 days has been on all the time. Wonder what has gone wrong now?.ImageUploadedByJeepGarage1453278984.522764.jpg

Re: Why is my engine light on?

Fuel cap? Our old WH threw the CEL (assuming it's hard on, not blinking) when the rubber seal gave way. Emission issue of course after it did that. A quick fix ensued.

Put it on a scanner to read the stored fault code.

Is it blinking or on solid?

Solid usually goes away in a few days of driving and may be due to missing TSBs, bad ground, leaks.

Blinking is when you head for the dealer.

Borrow a scanner or buy one and pull faults when it is on.

Re: Why is my engine light on?

Solid. Yes, I read the owners manual and it says if it is blinking straight to the dealer.

It just seems odd that it has been occurring reasonably often over the last few weeks.

I hope it is not a similar intermittent fault to my air bag light problem that took yonks to resolve.

I'm booked for a service next week so I'll see what they can find that might be causing the problem.

Nothing a "new" Jeep can't fix

Re: Why is my engine light on?

Ha ha ha. I remain conflicted on what to do. I've just paid the rego but only for 6 months - trying to force myself to make a decision....,

Re: Why is my engine light on?

I had an intermittent engine light problem - happened on the Kalumburu road in the Kimberly. Seemed to be triggered when I hit bumps. After a sat phone call to a service agent in Broome, I lived with it til I got there. Turned out to be a dirty O2 sensor. About the same time, we intermittently lost 4wd - which turned out to be a dirty wheel speed sensor. It's a worry, all these electronics....

Re: Why is my engine light on?

I have had the same situation a few times of late. I purchased a code reader late last year to try to understand the problem. 3.6l Laredo from late 2011.

For my error - It seems that the O2 sensor in front of the cat converter will have readings that vary based upon throttle etc but the O2 sensor at the rear of the cat should be fairly constant and if it in not, the error is recorded and the light comes on. After a number of engine starts the light will go off though the error record is maintained. I have chosen to ignore that error at this point and definitely not rush to a dealer.

I had been through near 2 years of problems from just before the first service, that had the light flashing on multiple occasions and ended up with the heads, the cat and multiple O2 sensors replaced and was still getting the light flashing and the vehicle vibrating due to cylinder misfires, then finally the transmission controller was replaced and things settled down until the recent situation above. It has 94K kilometres on the odo now.

The lease has ended so if I have another problem it is off the bone yard for the Jeep. As it stands I will never purchase another. Bad experiences are hard to forget (including the dealers attitude to the issues).

Regards
Bernard

Why is my engine light on?

Hear you loud and clear bjp. I've kept my current car too long beyond warranty - it was never my intention and I always planned to be rid of it at the 2.5 yr mark... But I waited for the MY16 which for us here in Aus seems not likely to materialise. Hindsight.....

I have dived in the deep end again and have another Jeep siting at a dealer waiting to be picked up, but my wife is on strict instruction to kick me in the unmentionables if I go past the 2.5yr period again.
