Lotus Service Notes Section GJ
When removing or replacing a tyre, be aware that the tyre valve includes a pressure transducer and should
not be discarded. Take care not to damage the sensor with the tyre bead or tools. If a fault is indicated after
wheel or tyre replacement, it is likely that a sensor has been incorrectly fitted or damaged. If a tyre valve/sensor
is renewed, or is moved to a different wheel position, the TPMS will automatically identify the new configuration
by interpreting signal strength as distance from sensor to receiver.
Note that the pressure sensors are powered by integral batteries, with an average service life of 10 years.
It is recommended to renew all pressure sensors at this time interval.
TPMS fault codes
On detection of a fault, the TPMS integrated diagnostics will set an appropriate code which may be read
using the Lotus Techcentre:
C0550 TPMS ECU Failure
C0551 TPMS Module not programmed with Vehicle Configuration
C0558 TPMS Vehicle Sensor ID's not programmed
C075A TPMS Pressure Sensor LF Malfunction / Battery Low / Broken Shock Sensor
C075B TPMS Pressure Sensor RF Malfunction / Battery Low / Broken Shock Sensor
C075C TPMS Pressure Sensor LR Malfunction / Battery Low / Broken Shock Sensor
C075D TPMS Pressure Sensor RR Malfunction / Battery Low / Broken Shock Sensor
C0777 TPMS Sensor Autolocation Failed
C0800 TPMS Module Supply Voltage Below 9V / Above 18V
U2103 TPMS Communications Malfunction
In the first instance, the car should be driven gently at 40 mph in order to optimise conditions for sensor
recognition. If the fault persists, the following action should be considered:
550/551/558 – most likely a TPMS module problem; renew
75A/B/C/D – most likely a pressure sensor; renew
777 – Most likely the module but could be a rogue sensor
800 – Check supply voltage and ground connection
U2103 – Could be module, CAN cable connection or engine T4e controller
GJ.3 - WHEELS
Standard wheels on the Lotus Evora are Lotus styled, cast alloy, 10-spoke arranged in pairs, silver or grey
painted, in sizes of 8.0J x 18 front, and 9.5J x19 rear. Optional forged alloy wheels are Lotus styled with 10
equally spaced radial spokes, but are otherwise similar. Each wheel is located by a central spigot and secured
by five bolts, four of which have a spline socket head, and one with a security coded head. A splined extension
tool and a coded adaptor are supplied with the vehicle and require a 17mm hex. socket, square drive extension
and a torque wrench.
