    Replacing a dmax right now because I thought it was the sender or cluster. So dont assume and let it go like I did. Turns out all those crankcases full of diesel due to bad injectors took its toll on the bearings.

    generally dmax's with oil pressure reading issues turn out to be clusters, the sender on a dmax is a isuzu part, hardly ever go bad

    It was the sender. I had to do the whole job by feel as the sender is hard to get at. Deep well socket, swivel, and a couple extensions and the job is done. I can now see my oil pressure again. Thanks for the help!!

    Mr. C
    If it's not the sender and is the cluster F@#* harness. double check with your dealer. My wifes 03 yukon went out (even though it was out of warranty) we had less than 100k miles on it and they replaced-no charge.

    Good Luck

    not really, kinda booger to get at but if you can borrow a oil pressure sender socket its a breeze. you may be able to get some channel locks on the base and pop it loose, once its broke loose it'll jus finger on out, they have alil compression washer that seals em up.

    My 05 Suburban was showing no oil pressure. Had it towed to the dealer in Claremont and it ended up being a bad sender. I think it was around $400 to change it.

    You're the man! There isn't really a rodent problem here so I'm going to shoot for the sender being the issue. Any quick / easy ways to get at it?

    Engine Oil Pressure Gauge
    The instrument panel cluster (IPC) displays the engine oil pressure as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gauge defaults to 0 kPa (0 psi) or below if:

    • The PCM detects a malfunction in the engine oil pressure sensor circuit.

    • The IPC detects a loss of class 2 communications with the PCM.

    with it chime'n like that i wouldnt think it was the cluster itself. the sender sends its signal to the pcm and the pcm sends it along to the ipc(cluster). the chime means what the ipc is getting from the pcm is showing to be too low a pressure. try a sender, bet itll fix ya up. could also be rats ate wires behind the intake near the sender, see'n that alot this time of yr

    Chevy Oil pressure electrical problem

    I know some of you know this truck like the back of your hand so hopefully someone can take the guess work out of what's going on here.

    2004 Chevy 1500 4x4 Silverado

    Originally the oil pressure gauge was pegged but now it goes from being pegged to 0 and back again at randon intervals. It also likes to "ding ding" and tell me the oil pressure is low. The oil pressure is not low (checked it) so this is an electrical issue.

    Is this typically a sender problem? chafed wire? gauge cluster?

    Thanks for any help!
