    '88 CS CEL when reversing warm

    Hey, My '88 Country Squire has the Engine light coming on (Just the red "ENGINE" box). Only in reverse. Only when the car is fully warmed up.

    Any ideas on what it could be?

    I was going to get it into the mechanic's to get it checked out, but I bought the '94 CV off my bro and it's in the shop to have its laundry list taken care of.

    Thanks for your help, everyone!

    It's grounding somewhere. That's assuming you have oil pressure, and that it's not overheating. Check the wiring for the oil pressure switch, and the coolant temp switch to make sure that the wires aren't grounding somewhere. If it's just happening in reverse, I'm wondering if the wire isn't caught in a motor mount or, if the mount is bad, the engine is moving more than it should, and is rubbing against the wire and grounding it.

      that would make sense to me. The red light of death is for overheating or no oil pressure. It doesn't make sense that either would happen only in reverse. Pinched or damaged wire sounds a lot more probable.

        Results: KOEO test: 34 O & 34 C or R (ran a couple of times.

        EGR Valve not opening properly, Insufficient EGR flow or EVP voltage high (SONIC), or PFE sensor voltage high or out of specification.

        Results: KOER test: 94, 44, 34, & 74

        I'm not sure if the 94 was O or R. O= Converter Clutch Control (CCC) circuit failure. R=Air Diverter solenoid circuit fault.

        44 is Thermactor air system fault

        34 is EGR again of course

        and 74 was probably my dumb ass doing something wrong on the testing as it means "Brake On/Off switch fault; not actuated."


        So should I just unplug the EGR hose and ignore it, or what? Plus I don't know if any of that other shit is important or not.

        Any advice would be much appreciated. I'm leaving my dash torn apart on the '94 until the LEDs I ordered get here (next week I hope) and driving the waggin' everywhere.

          44 and 94 are smog pump related. if your pump is gone, thats why. ignore this. If the pump and all that is present, the heads are carboned shut. Continue to ignore this.
          74 is operator error, ignore this
          34 is usually the egr sensor or the egr valve has a nugget of crap under the pintle. This the only one that might be a problem. If it was 33, it won't affect things but you need to make sure the egr valve is completely closed otherwise it will run funny.

          none of those codes are remotely related to the red light of death, unless you're talking about the amber light of annoyance. If its the amber lamp of annoyance, the code 34 is what causes that. Almost nothing trips that on except egr shit.

            Thanks.

            I'm driving the car sparingly (just 2 miles to work & 2 miles back) for the most part in case it's the oil pump or whatever.

            I don't know if the '88 Country Squire even has an Amber CEL. I've never seen it come on.

            Should I just take off the EGR and try to scrape/clean it out? Would removing the vaccuum line and plugging it with a screw do anything?

              Yeah, red light of death is almost certainly the oil pump. Now @ stoplights it flickers or comes on. I can make it go out by putting the car in Neutral for now... so that's what I'm gonna have to do.

              I'm not paying $450 labor when I can likely save up and do a HO swap (myself) or something more radical eventually if my mechanic says the car is in good enough shape to keep.

                put 20w50 in it and keep driving. Fords dont need oil pressure, they need oil flow. Its also almost definitely not the pump. Its usually the bearings in the motor are wiped out, so a pump is not likely to fix anything but cure you of a heavy wallet.

                  Thanks for the suggestion, I'm dropping it off at the mechanic's today!

                    And you're going to have him do what? A crank kit? For all that effort, you may as well put an explorer motor in there.

                      yeah. The only fix is a bottom end rebuild, and thats just too pricey to be worth it. Motor swap time, or time for electrical tape and thick oil. Thick oil in the motor, tape over the light. Turn the radio up and ignore the noises.

                        He's gonna put an oil pressure gauge on it to test and then change it to "racing oil" (the 20w50 or w/e).

                        I'm thinking about what to do with the car in the future it's got some minor-to-medium body rust, but afaik the frame is good and I've had the fuel lines replaced where they needed it.

                        There's currently a 5.0 HO + AOD Lincoln LSC that was flipped on CL here for $450. http://akroncanton.craigslist.org/pts/1917446356.html

                        Or there's always 460s + C6es.

                        This is my backup/toy car now, so how wild I get with it depends on how much money I can save up. Running it until it dies, and then we'll see!

                        The funny thing is, first it starts smelling like waffles, then you start to smell burning oil once the car is fully warmed up.

                          Finally heard back from my mang, after 2 1/2 weeks.

                          Oil pressure cold 45 psi, warm 7.

                          New oil pressure warm 15 psi, enough not to trip the Red Engine light of death for now.
