1997 Isuzu Trooper Problems
RepairPal has identified the most common problems with the 1997 Isuzu Trooper based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wiring may be of help it this case.
A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.
A rattling type noise may develop from the front of the engine. This is commonly caused by a faulty timing chain tensioner. Replacement of the failed tensioner should correct this concern.
