Default Oil pressure drop and loss of power steering

Hi all,

I've been lurking and learning a lot on this forum for the past few months. I purchased an 06 Ram hemi back in July. This week I've had a couple of issues creep up and I'd like the Ramforumz hive mind to help me diagnose them before I take it into the shop.

First I've had the ABS and brake lights come on twice this week while driving. Both times they stayed on until I cycled the key. The first time was after taking off on an uphill slope, the second occurred when taking off on a downhill slope.

I've not had a chance to check yet, but I'm thinking it might be the brake fluid level. The other likely culprit I've read about is a faulty ABS sensor or wiring. Any other ideas?

Secondly, this morning after filling up the gas tank I was stopped at an intersection and the oil pressure gage dropped to zero, the check gages light came on and I lost power steering. After restarting the truck, everything returned back to normal.

From what I've gathered so far from others, it seems the likely issues and fixes may be the oil pressure switch and sending unit, and/or dropping the pan and cleaning the intake screen of any possible debris. What is throwing me off is the loss of power steering when this occurred. Has anyone else had this happen to them at all?

Thanks,

Matt

Let's start with the ABS. While a low fluid level will cause the red brake lamp to come on, it shouldn't cause the ABS light to illuminate. You need to have the ABS module scanned and find out what the codes are.

Is the loss of oil pressure a problem easily duplicated or was it an isolated incident?You should start with the obvious and verify the oil level is correct. If it's ok, I would want to verify pressure with a mechanical gauge.

Thanks guys, from the sound of it I need to check my fluid levels and get it into a shop to see if they can pull any codes and find a solution.

If the engine stalls, you'll lose oil pressure and power steering. You mentioned restarting the engine, so I'm guessing that's what happened. I'm troubleshooting a stalling when driving issue on my RAM, and when it occurs I have similar symptoms (i.e. Check Gauges light, oil pressure drops, etc.).

That does seem like the likely cause. So far it has only happened that once.

Regarding the ABS/Brake Light issue, it took my shop three days (can anyone recommend a new shop in South St Louis or South County?)to pull a code, c1008, which references low brake fluid. Brake fluid is fine and the mechanics said the likely cause is a malfunctioning sensor in the master cylinder or controller, but can't tell me more without taking a closer look.

Doesn't seem like a serious problem, so I'll be waiting until after the holidays to get it fixed.

Matt
