P1211 & P1280

Hello everyone.

My truck has been feeling liek the power was falling off the last week or so. Wrote it off to hot weather, and actually working it (hualing firewood, etc...)

Sunday after a day at the lake , got off the freeway and everything fell apart. Got a cam sensor code when I came off the throttle (replaced the sensor, no change).

Now I am getting P1211's & (1) P1280 (uncontrollable icp, & icp low). Will not hardly run/start when warm, starts cold and has some power, but is still not right. Fuel pressure hold at 60 psi under throttle, but bounces from 60-100+ when fighting to idle (surge & sputter when warm). I do not have a guage to monitor ICP pressure.

Went back to stock programming, no effect.

Oil has 2400 miles +/-, and is full.

Exhaust "smells" good, not rich or anything. Still can get Low sulfur here & run cetane boost always.

99.5, 4x4, auto, 4" exhuast, (dreaded) K&N intake, Superchips 1705 usually in Tow safe mode.

Please help, do not have money to throw at it!!!!!

check the wiring going itno the icp conetor make sure its not frayed , very possible icp sensor bad internally , would give that 1280 code , p1211 can be caused by 1280 code, address 1280 first

Thanks Scuffy.

I did pull the plug from the sensor last night. No change (at least in the driveway) in running, but the check engine light stayed on.

The check light does not come on until I just drop my foot into things, which is currently required to get it rolling 70 once warm.

I will make a more thorugh visual of the connector.

The P1280 code has only come up once, while the 1211 is pretty consistent.

Checking the O-ring...

Any good advice on how to check this? I have a Chilton's but it is rather lacking... Have not looked for this in that manual yet, need to get home first, but maybe someone has some good techniques/tips that are not always listed.

Thanks any/everyone!!!

Checked all the sensor connections, visually everything is fine.

Checked IP O-ring areas, all clean.

Unhooked ICP sensor, and took the truck for a drive. Except for a bit of smoke around idle and a definate rich smell, it performed (or lack of) exactly the same, getting worse as it came up to temperature.

Constant check engine with sensor unhooked, coded the same codes, 1211 & 1280 as i get with it hooked up. I cleared the codes before running it, so those were fresh to the no sensor run.

Is this a good indicator the sensor fried? And is just within spec enough to not pull a constant check engine when hooked up?

I am running Delo 400 for oil, it is several hundred ahead of change. Oil does not smell and looks pretty clean.

All input appreciated.

Ok, and Nope.

Anyone got a good link on location?

Sorry guys, I have only had the truck for a little over a year, still learning to deeper parts......

The crappy chilton's manual only tells you to remove it if replacing the whole pump unit. Is this going to require removing the pump, lines, etc?

Thanks Scuffy

do not have to take pup off, disconect two wire connector, use 19mm wrench or 3/4 and take the nut off the back, slide the solenoid off the end , then with a 1 1/16 socket take the ipr out of the pump inspect o-rings , if look ok reinstall, if there is a problem its usually fairly obvious with the o-ring
