Hi all, I have a 1999 s type 4.0 v8, the last to night I have had a flashing engine light appear on my way home from work about 5 to 10 minutes into the journey. It also turned over a little longer than usual before starting. My elm dongle show no fault codes (pobablly due to the flashing engine light stopping after a minute or 2) but does have a sensor out of range, tid$10 cid$11 shows as 64 and say max 51, I thought this was due to the previous owner installing a aftermarket cone style air filter which I removed and returned to the OEM air filter and box, but this had the opposite effect as it showed 54 when I first got the car before changed it. This is the only sensor I can find that isn't green or within specs but I don't know what it relates to as I'm only using torque and a dongle. The car seems to drive fine while its flashing just concerned that this could be a precursor to something, and ideas?

 

Do not operate the vehicle under conditions that cause the MIL to flash as catalyst damage is occurring. Find and correct any misfire(s) to avoid catalyst damage.

Failing coil units don't always set a DTC, but it may be wise to inspect all eight coil units for oil fouling or having water in the spark plug wells. If there is oil in the spark plug wells, the cam cover gaskets and spark plug boss seals must be replaced. Depending on the number of kilometres/miles on the vehicle, the spark plugs should be replaced as well.

 

I thought I remember you stating no drive with flashing engine light NB..I was just doing a search to verify when your reply posted....good job my friend

 

Thanks for the info, think I might just replace the coils and plugs anyway as the previous owner didn't know when they were last done, still concerned about the high sensor value could it be one of the o2 sensors?

 

It could be the misfire monitor, but until you know what the value 64 relates to it is just a guessing game....wish I could be more help...you might also have a pending code that has not set as a hard code
