P1259 and P1262 Fault Codes on Toyota Land Cruiser with 1VD Engine After Replacement

Model: Land Cruiser Fault Code: P1259 Posted: 2019-03-19 02:53

Hi everyone, After replacing the 1VD engine in my Toyota Land Cruiser, I'm now seeing fault codes P1259 and P1262. Both the Check Engine light and the 4LO gear indicator light are illuminated. The issue appears to be related to the transmission control system after the engine swap. I'm looking for advice on how to diagnose and resolve these specific OBD-II codes in a Land Cruiser with a 1VD engine. Any insights or solutions from experienced users would be greatly appreciated.

Hi, I'm experiencing the same issue after replacing two complete turbos. The P1259 and P1262 codes are appearing, along with the 4LO light on. Any suggestions on how to fix this? Thanks.
