I bought this civic recently and it’s giving me a headache. It cranks and has difficulty starting cold, and will also stall quite a few times before running steady. Every time it starts, the battery light appears regardless of if it’s warm or cold until I hit the gas a few times and then it goes away.
It’s throwing three codes at me: p0113, p0118, and p0123. I changed all three sensors that relates with each code, however none of them seem to be working. Whenever I hook up the scanner to get a reading on the engine coolant temperature or the intake air temperature, it just reads 0. (Also I checked my other civic with the scanner and got readings of each sensor) I’ve also checked the ground by the thermostat and that seems like it’s in good shape. Whenever I reset the ecu with the scanner, the Check Engine Light immediately comes back on.
Before I came inside tonight it threw one more code at me: p1108. If anybody has any insight on where I should go from here I’d appreciate it.
Also!! The guy I bought it from has an aftermarket radio system installed with a subwoofer in the trunk. They wired it directly to the battery, but it is disconnected at the moment and my problems haven’t changed.
